- Plugin & Theme hooks/helpers API
- Tips
Concepts
Themes are exactly the same as plugins, except that:
- Their name starts with
peertube-theme-
instead ofpeertube-plugin-
- They cannot declare server code (so they cannot register server hooks or settings)
- CSS files are loaded by client only if the theme is chosen by the administrator or the user
Hooks
A plugin registers functions in JavaScript to execute when PeerTube (server and client) fires events. There are 3 types of hooks:
filter
: used to filter functions parameters or return values. For example to replace words in video comments, or change the videos list behaviouraction
: used to do something after a certain trigger. For example to send a hook every time a video is publishedstatic
: same thanaction
but PeerTube waits their execution
On server side, these hooks are registered by the library
file defined in package.json
.
{
...,
"library": "./main.js",
...,
}
And main.js
defines a register
function:
Example:
async function register ({
registerHook,
registerSetting,
settingsManager,
storageManager,
videoCategoryManager,
videoLicenceManager,
videoLanguageManager,
peertubeHelpers,
getRouter,
registerExternalAuth,
unregisterExternalAuth,
registerIdAndPassAuth,
unregisterIdAndPassAuth
}) {
registerHook({
target: 'action:application.listening',
handler: () => displayHelloWorld()
})
}
Hooks prefixed by action:api
also give access the original express Request and Response:
async function register ({
registerHook,
peertubeHelpers: { logger }
}) {
registerHook({
target: 'action:api.video.updated',
handler: ({ req, res }) => logger.debug('original request parameters', { params: req.params })
})
}
On client side, these hooks are registered by the clientScripts
files defined in package.json
.
All client scripts have scopes so PeerTube client only loads scripts it needs:
{
...,
"clientScripts": [
{
"script": "client/common-client-plugin.js",
"scopes": [ "common" ]
},
{
"script": "client/video-watch-client-plugin.js",
"scopes": [ "video-watch" ]
}
],
...
}
And these scripts also define a register
function:
function register ({ registerHook, peertubeHelpers }) {
registerHook({
target: 'action:application.init',
handler: () => onApplicationInit(peertubeHelpers)
})
}
Static files
Plugins can declare static directories that PeerTube will serve (images for example)
from /plugins/{plugin-name}/{plugin-version}/static/
or /themes/{theme-name}/{theme-version}/static/
routes.
CSS
Plugins can declare CSS files that PeerTube will automatically inject in the client.
If you need to override existing style, you can use the #custom-css
selector:
body#custom-css {
color: red;
}
#custom-css .header {
background-color: red;
}
Server API (only for plugins)
Settings
Plugins can register settings, that PeerTube will inject in the administration interface.
The following fields will be automatically translated using the plugin translation files: label
, html
, descriptionHTML
, options.label
.
These fields are injected in the plugin settings page as HTML, so pay attention to your translation files.
Example:
function register (...) {
registerSetting({
name: 'admin-name',
label: 'Admin name',
type: 'input',
// type: 'input' | 'input-checkbox' | 'input-password' | 'input-textarea' | 'markdown-text' | 'markdown-enhanced' | 'select' | 'html'
// If type: 'select', give the select available options
options: [
{ label: 'Label 1', value: 'value1' },
{ label: 'Label 2', value: 'value2' }
],
// If type: 'html', set the HTML that will be injected in the page
html: '<strong class="...">Hello</strong><br /><br />'
// Optional
descriptionHTML: 'The purpose of this field is...',
default: 'my super name',
// If the setting is not private, anyone can view its value (client code included)
// If the setting is private, only server-side hooks can access it
private: false
})
const adminName = await settingsManager.getSetting('admin-name')
const result = await settingsManager.getSettings([ 'admin-name', 'admin-password' ])
result['admin-name]
settingsManager.onSettingsChange(settings => {
settings['admin-name']
})
}
Storage
Plugins can store/load JSON data, that PeerTube will store in its database (so don't put files in there).
Example:
function register ({
storageManager
}) {
const value = await storageManager.getData('mykey')
await storageManager.storeData('mykey', { subkey: 'value' })
}
You can also store files in the plugin data directory (/{plugins-directory}/data/{npm-plugin-name}
) in PeerTube >= 3.2.
This directory and its content won't be deleted when your plugin is uninstalled/upgraded.
function register ({
storageManager,
peertubeHelpers
}) {
const basePath = peertubeHelpers.plugin.getDataDirectoryPath()
fs.writeFile(path.join(basePath, 'filename.txt'), 'content of my file', function (err) {
...
})
}
Update video constants
You can add/delete video categories, licences or languages using the appropriate constant managers:
function register ({
videoLanguageManager,
videoCategoryManager,
videoLicenceManager,
videoPrivacyManager,
playlistPrivacyManager
}) {
videoLanguageManager.addConstant('al_bhed', 'Al Bhed')
videoLanguageManager.deleteConstant('fr')
videoCategoryManager.addConstant(42, 'Best category')
videoCategoryManager.deleteConstant(1) // Music
videoCategoryManager.resetConstants() // Reset to initial categories
videoCategoryManager.getConstants() // Retrieve all category constants
videoLicenceManager.addConstant(42, 'Best licence')
videoLicenceManager.deleteConstant(7) // Public domain
videoPrivacyManager.deleteConstant(2) // Remove Unlisted video privacy
playlistPrivacyManager.deleteConstant(3) // Remove Private video playlist privacy
}
Add custom routes
You can create custom routes using an express Router for your plugin:
function register ({
router
}) {
const router = getRouter()
router.get('/ping', (req, res) => res.json({ message: 'pong' }))
// Users are automatically authenticated
router.get('/auth', async (res, res) => {
const user = await peertubeHelpers.user.getAuthUser(res)
const isAdmin = user.role === 0
const isModerator = user.role === 1
const isUser = user.role === 2
res.json({
username: user.username,
isAdmin,
isModerator,
isUser
})
})
}
The ping
route can be accessed using:
/plugins/:pluginName/:pluginVersion/router/ping
- Or
/plugins/:pluginName/router/ping
Add external auth methods
If you want to add a classic username/email and password auth method (like LDAP for example):
function register (...) {
registerIdAndPassAuth({
authName: 'my-auth-method',
// PeerTube will try all id and pass plugins in the weight DESC order
// Exposing this value in the plugin settings could be interesting
getWeight: () => 60,
// Optional function called by PeerTube when the user clicked on the logout button
onLogout: user => {
console.log('User %s logged out.', user.username')
},
// Optional function called by PeerTube when the access token or refresh token are generated/refreshed
hookTokenValidity: ({ token, type }) => {
if (type === 'access') return { valid: true }
if (type === 'refresh') return { valid: false }
},
// Used by PeerTube when the user tries to authenticate
login: ({ id, password }) => {
if (id === 'user' && password === 'super password') {
return {
username: 'user'
email: 'user@example.com'
role: 2
displayName: 'User display name'
}
}
// Auth failed
return null
}
})
// Unregister this auth method
unregisterIdAndPassAuth('my-auth-method')
}
You can also add an external auth method (like OpenID, SAML2 etc):
function register (...) {
// result contains the userAuthenticated auth method you can call to authenticate a user
const result = registerExternalAuth({
authName: 'my-auth-method',
// Will be displayed in a button next to the login form
authDisplayName: () => 'Auth method'
// If the user click on the auth button, PeerTube will forward the request in this function
onAuthRequest: (req, res) => {
res.redirect('https://external-auth.example.com/auth')
},
// Same than registerIdAndPassAuth option
// onLogout: ...
// Same than registerIdAndPassAuth option
// hookTokenValidity: ...
})
router.use('/external-auth-callback', (req, res) => {
// Forward the request to PeerTube
result.userAuthenticated({
req,
res,
username: 'user'
email: 'user@example.com'
role: 2
displayName: 'User display name'
})
})
// Unregister this external auth method
unregisterExternalAuth('my-auth-method)
}
Add new transcoding profiles
Adding transcoding profiles allow admins to change ffmpeg encoding parameters and/or encoders. A transcoding profile has to be chosen by the admin of the instance using the admin configuration.
async function register ({
transcodingManager
}) {
// Adapt bitrate when using libx264 encoder
{
const builder = (options) => {
const { input, resolution, fps, streamNum } = options
const streamString = streamNum ? ':' + streamNum : ''
// You can also return a promise
// All these options are optional
return {
scaleFilter: {
// Used to define an alternative scale filter, needed by some encoders
// Default to 'scale'
name: 'scale_vaapi'
},
// Default to []
inputOptions: [],
// Default to []
outputOptions: [
// Use a custom bitrate
'-b' + streamString + ' 10K'
]
}
}
const encoder = 'libx264'
const profileName = 'low-quality'
// Support this profile for VOD transcoding
transcodingManager.addVODProfile(encoder, profileName, builder)
// And/Or support this profile for live transcoding
transcodingManager.addLiveProfile(encoder, profileName, builder)
}
{
const builder = (options) => {
const { streamNum } = options
const streamString = streamNum ? ':' + streamNum : ''
// Always copy stream when PeerTube use libfdk_aac or aac encoders
return {
copy: true
}
}
const profileName = 'copy-audio'
for (const encoder of [ 'libfdk_aac', 'aac' ]) {
transcodingManager.addVODProfile(encoder, profileName, builder)
}
}
PeerTube will try different encoders depending on their priority. If the encoder is not available in the current transcoding profile or in ffmpeg, it tries the next one. Plugins can change the order of these encoders and add their custom encoders:
async function register ({
transcodingManager
}) {
// Adapt bitrate when using libx264 encoder
{
const builder = () => {
return {
inputOptions: [],
outputOptions: []
}
}
// Support libopus and libvpx-vp9 encoders (these codecs could be incompatible with the player)
transcodingManager.addVODProfile('libopus', 'test-vod-profile', builder)
// Default priorities are ~100
// Lowest priority = 1
transcodingManager.addVODEncoderPriority('audio', 'libopus', 1000)
transcodingManager.addVODProfile('libvpx-vp9', 'test-vod-profile', builder)
transcodingManager.addVODEncoderPriority('video', 'libvpx-vp9', 1000)
transcodingManager.addLiveProfile('libopus', 'test-live-profile', builder)
transcodingManager.addLiveEncoderPriority('audio', 'libopus', 1000)
}
During live transcode input options are applied once for each target resolution. Plugins are responsible for detecting such situation and applying input options only once if necessary.
Server helpers
PeerTube provides your plugin some helpers. For example:
async function register ({
peertubeHelpers
}) {
// Block a server
{
const serverActor = await peertubeHelpers.server.getServerActor()
await peertubeHelpers.moderation.blockServer({ byAccountId: serverActor.Account.id, hostToBlock: '...' })
}
// Load a video
{
const video = await peertubeHelpers.videos.loadByUrl('...')
}
}
See the plugin API reference to see the complete helpers list.
Client API (themes & plugins)
Get plugin static and router routes
To get your plugin static route:
function register (...) {
const baseStaticUrl = peertubeHelpers.getBaseStaticRoute()
const imageUrl = baseStaticUrl + '/images/chocobo.png'
}
And to get your plugin router route, use peertubeHelpers.getBaseRouterRoute()
:
function register (...) {
registerHook({
target: 'action:video-watch.video.loaded',
handler: ({ video }) => {
fetch(peertubeHelpers.getBaseRouterRoute() + '/my/plugin/api', {
method: 'GET',
headers: peertubeHelpers.getAuthHeader()
}).then(res => res.json())
.then(data => console.log('Hi %s.', data))
}
})
}
Notifier
To notify the user with the PeerTube ToastModule:
function register (...) {
const { notifier } = peertubeHelpers
notifier.success('Success message content.')
notifier.error('Error message content.')
}
Markdown Renderer
To render a formatted markdown text to HTML:
function register (...) {
const { markdownRenderer } = peertubeHelpers
await markdownRenderer.textMarkdownToHTML('**My Bold Text**')
// return <strong>My Bold Text</strong>
await markdownRenderer.enhancedMarkdownToHTML('![alt-img](http://.../my-image.jpg)')
// return <img alt=alt-img src=http://.../my-image.jpg />
}
Auth header
PeerTube >= 3.2
To make your own HTTP requests using the current authenticated user, use an helper to automatically set appropriate headers:
function register (...) {
registerHook({
target: 'action:auth-user.information-loaded',
handler: ({ user }) => {
// Useless because we have the same info in the ({ user }) parameter
// It's just an example
fetch('/api/v1/users/me', {
method: 'GET',
headers: peertubeHelpers.getAuthHeader()
}).then(res => res.json())
.then(data => console.log('Hi %s.', data.username))
}
})
}
Custom Modal
To show a custom modal:
function register (...) {
peertubeHelpers.showModal({
title: 'My custom modal title',
content: '<p>My custom modal content</p>',
// Optionals parameters :
// show close icon
close: true,
// show cancel button and call action() after hiding modal
cancel: { value: 'cancel', action: () => {} },
// show confirm button and call action() after hiding modal
confirm: { value: 'confirm', action: () => {} },
})
}
Translate
You can translate some strings of your plugin (PeerTube will use your translations
object of your package.json
file):
function register (...) {
peertubeHelpers.translate('User name')
.then(translation => console.log('Translated User name by ' + translation))
}
Get public settings
To get your public plugin settings:
function register (...) {
peertubeHelpers.getSettings()
.then(s => {
if (!s || !s['site-id'] || !s['url']) {
console.error('Matomo settings are not set.')
return
}
// ...
})
}
Get server config
function register (...) {
peertubeHelpers.getServerConfig()
.then(config => {
console.log('Fetched server config.', config)
})
}
Add custom fields to video form
To add custom fields in the video form (in Plugin settings tab):
async function register ({ registerVideoField, peertubeHelpers }) {
const descriptionHTML = await peertubeHelpers.translate(descriptionSource)
const commonOptions = {
name: 'my-field-name,
label: 'My added field',
descriptionHTML: 'Optional description',
// type: 'input' | 'input-checkbox' | 'input-password' | 'input-textarea' | 'markdown-text' | 'markdown-enhanced' | 'select' | 'html'
// /!\ 'input-checkbox' could send "false" and "true" strings instead of boolean
type: 'input-textarea',
default: '',
// Optional, to hide a field depending on the current form state
// liveVideo is in the options object when the user is creating/updating a live
// videoToUpdate is in the options object when the user is updating a video
hidden: ({ formValues, videoToUpdate, liveVideo }) => {
return formValues.pluginData['other-field'] === 'toto'
},
// Optional, to display an error depending on the form state
error: ({ formValues, value }) => {
if (formValues['privacy'] !== 1 && formValues['privacy'] !== 2) return { error: false }
if (value === true) return { error: false }
return { error: true, text: 'Should be enabled' }
}
}
const videoFormOptions = {
// Optional, to choose to put your setting in a specific tab in video form
// type: 'main' | 'plugin-settings'
tab: 'main'
}
for (const type of [ 'upload', 'import-url', 'import-torrent', 'update', 'go-live' ]) {
registerVideoField(commonOptions, { type, ...videoFormOptions })
}
}
PeerTube will send this field value in body.pluginData['my-field-name']
and fetch it from video.pluginData['my-field-name']
.
So for example, if you want to store an additional metadata for videos, register the following hooks in server:
async function register ({
registerHook,
storageManager
}) {
const fieldName = 'my-field-name'
// Store data associated to this video
registerHook({
target: 'action:api.video.updated',
handler: ({ video, body }) => {
if (!body.pluginData) return
const value = body.pluginData[fieldName]
if (!value) return
storageManager.storeData(fieldName + '-' + video.id, value)
}
})
// Add your custom value to the video, so the client autofill your field using the previously stored value
registerHook({
target: 'filter:api.video.get.result',
handler: async (video) => {
if (!video) return video
if (!video.pluginData) video.pluginData = {}
const result = await storageManager.getData(fieldName + '-' + video.id)
video.pluginData[fieldName] = result
return video
}
})
}
Register settings script
To hide some fields in your settings plugin page depending on the form state:
async function register ({ registerSettingsScript }) {
registerSettingsScript({
isSettingHidden: options => {
if (options.setting.name === 'my-setting' && options.formValues['field45'] === '2') {
return true
}
return false
}
})
}
Plugin selector on HTML elements
PeerTube provides some selectors (using id
HTML attribute) on important blocks so plugins can easily change their style.
For example #plugin-selector-login-form
could be used to hide the login form.
See the complete list on https://docs.joinpeertube.org/api-plugins
HTML placeholder elements
PeerTube provides some HTML id so plugins can easily insert their own element:
async function register (...) {
const elem = document.createElement('div')
elem.className = 'hello-world-h4'
elem.innerHTML = '<h4>Hello everybody! This is an element next to the player</h4>'
document.getElementById('plugin-placeholder-player-next').appendChild(elem)
}
See the complete list on https://docs.joinpeertube.org/api-plugins
Add/remove left menu links
Left menu links can be filtered (add/remove a section or add/remove links) using the filter:left-menu.links.create.result
client hook.
Create client page
To create a client page, register a new client route:
function register ({ registerClientRoute }) {
registerClientRoute({
route: 'my-super/route',
onMount: ({ rootEl }) => {
rootEl.innerHTML = 'hello'
}
})
}
Publishing
PeerTube plugins and themes should be published on NPM so that PeerTube indexes take into account your plugin (after ~ 1 day). An official plugin index is available on packages.joinpeertube.org, with no interface to present packages.
The official plugin index source code is available at https://framagit.org/framasoft/peertube/plugin-index
Write a plugin/theme
Steps:
- Find a name for your plugin or your theme (must not have spaces, it can only contain lowercase letters and
-
) - Add the appropriate prefix:
- If you develop a plugin, add
peertube-plugin-
prefix to your plugin name (for example:peertube-plugin-mysupername
) - If you develop a theme, add
peertube-theme-
prefix to your theme name (for example:peertube-theme-mysupertheme
)
- If you develop a plugin, add
- Clone the quickstart repository
- Configure your repository
- Update
README.md
- Update
package.json
- Register hooks, add CSS and static files
- Test your plugin/theme with a local PeerTube installation
- Publish your plugin/theme on NPM
Clone the quickstart repository
If you develop a plugin, clone the peertube-plugin-quickstart
repository:
$ git clone https://framagit.org/framasoft/peertube/peertube-plugin-quickstart.git peertube-plugin-mysupername
If you develop a theme, clone the peertube-theme-quickstart
repository:
$ git clone https://framagit.org/framasoft/peertube/peertube-theme-quickstart.git peertube-theme-mysupername
Configure your repository
Set your repository URL:
$ cd peertube-plugin-mysupername # or cd peertube-theme-mysupername
$ git remote set-url origin https://your-git-repo
Update README
Update README.md
file:
$ $EDITOR README.md
Update package.json
Update the package.json
fields:
name
(should start withpeertube-plugin-
orpeertube-theme-
)description
homepage
author
bugs
engine.peertube
(the PeerTube version compatibility, must be>=x.y.z
and nothing else)
Caution: Don't update or remove other keys, or PeerTube will not be able to index/install your plugin.
If you don't need static directories, use an empty object
:
{
...,
"staticDirs": {},
...
}
And if you don't need CSS or client script files, use an empty array
:
{
...,
"css": [],
"clientScripts": [],
...
}
Write code
Now you can register hooks or settings, write CSS and add static directories to your plugin or your theme :) It's up to you to check the code you write will be compatible with the PeerTube NodeJS version, and will be supported by web browsers.
JavaScript
If you want to write modern JavaScript, please use a transpiler like Babel.
Typescript
If you want to use Typescript, you can add PeerTube types as dev dependencies:
npm install --save-dev @peertube/peertube-types
This package exposes server definition files by default:
import { RegisterServerOptions } from '@peertube/peertube-types'
export async function register ({ registerHook }: RegisterServerOptions) {
registerHook({
target: 'action:application.listening',
handler: () => displayHelloWorld()
})
}
But it also exposes client types and various models used in PeerTube:
import { Video } from '@peertube/peertube-types';
import { RegisterClientOptions } from '@peertube/peertube-types/client';
function register({ registerHook, peertubeHelpers }: RegisterClientOptions) {
registerHook({
target: 'action:admin-plugin-settings.init',
handler: ({ npmName }: { npmName: string }) => {
if ('peertube-plugin-transcription' !== npmName) {
return;
}
},
});
registerHook({
target: 'action:video-watch.video.loaded',
handler: ({ video }: { video: Video }) => {
fetch(`${peertubeHelpers.getBaseRouterRoute()}/videos/${video.uuid}/captions`, {
method: 'PUT',
headers: peertubeHelpers.getAuthHeader(),
}).then((res) => res.json())
.then((data) => console.log('Hi %s.', data));
},
});
}
export { register };
Add translations
If you want to translate strings of your plugin (like labels of your registered settings), create a file and add it to package.json
:
{
...,
"translations": {
"fr": "./languages/fr.json",
"pt-BR": "./languages/pt-BR.json"
},
...
}
The key should be one of the locales defined in i18n.ts.
Translation files are just objects, with the english sentence as the key and the translation as the value.
fr.json
could contain for example:
{
"Hello world": "Hello le monde"
}
Build your plugin
If you added client scripts, you'll need to build them using webpack.
Install webpack:
$ npm install
Add/update your files in the clientFiles
array of webpack.config.js
:
$ $EDITOR ./webpack.config.js
Build your client files:
$ npm run build
You built files are in the dist/
directory. Check package.json
to correctly point to them.
Test your plugin/theme
PeerTube dev server (ran with npm run dev
on localhost:3000
) can't inject plugin CSS.
It's the reason why we don't use the dev mode but build PeerTube instead.
You'll need to have a local PeerTube instance:
- Follow the dev prerequisites (to clone the repository, install dependencies and prepare the database)
- Build PeerTube:
$ npm run build
- Build the CLI:
$ npm run setup:cli
- Run PeerTube (you can access to your instance on http://localhost:9000):
$ NODE_ENV=test npm start
- Register the instance via the CLI:
$ node ./dist/server/tools/peertube.js auth add -u 'http://localhost:9000' -U 'root' --password 'test'
Then, you can install or reinstall your local plugin/theme by running:
$ node ./dist/server/tools/peertube.js plugins install --path /your/absolute/plugin-or-theme/path
Publish
Go in your plugin/theme directory, and run:
$ npm publish
Every time you want to publish another version of your plugin/theme, just update the version
key from the package.json
and republish it on NPM. Remember that the PeerTube index will take into account your new plugin/theme version after ~24 hours.
If you need to force your plugin update on a specific PeerTube instance, you may update the latest available version manually:
UPDATE "plugin" SET "latestVersion" = 'X.X.X' WHERE "plugin"."name" = 'plugin-shortname';
You'll then be able to click the Update plugin button on the plugin list.
Unpublish
If for a particular reason you don't want to maintain your plugin/theme anymore you can deprecate it. The plugin index will automatically remove it preventing users to find/install it from the PeerTube admin interface:
$ npm deprecate peertube-plugin-xxx@"> 0.0.0" "explain here why you deprecate your plugin/theme"

Tips
Compatibility with PeerTube
Unfortunately, we don't have enough resources to provide hook compatibility between minor releases of PeerTube (for example between 1.2.x
and 1.3.x
).
So please:
- Don't make assumptions and check every parameter you want to use. For example:
registerHook({
target: 'filter:api.video.get.result',
handler: video => {
// We check the parameter exists and the name field exists too, to avoid exceptions
if (video && video.name) video.name += ' <3'
return video
}
})
- Don't try to require parent PeerTube modules, only use
peertubeHelpers
. If you need another helper or a specific hook, please create an issue - Don't use PeerTube dependencies. Use your own :)
If your plugin is broken with a new PeerTube release, update your code and the peertubeEngine
field of your package.json
field.
This way, older PeerTube versions will still use your old plugin, and new PeerTube versions will use your updated plugin.
Spam/moderation plugin
If you want to create an antispam/moderation plugin, you could use the following hooks:
filter:api.video.upload.accept.result
: to accept or not local uploadsfilter:api.video-thread.create.accept.result
: to accept or not local threadfilter:api.video-comment-reply.create.accept.result
: to accept or not local repliesfilter:api.video-threads.list.result
: to change/hide the text of threadsfilter:api.video-thread-comments.list.result
: to change/hide the text of repliesfilter:video.auto-blacklist.result
: to automatically blacklist local or remote videos
Other plugin examples
You can take a look to "official" PeerTube plugins if you want to take inspiration from them: https://framagit.org/framasoft/peertube/official-plugins
