React Transcript Editor

A React component to make transcribing audio and video easier and faster.


The project uses this github project boards to organise and the co-ordinate development.

--> Work in progress <--

Development env

Node version is set in node version manager .nvmrc

Setup

Fork this repository + git clone + cd into folder

Usage - development

Git clone this repository and cd into the folder.

To start the storybook run

npm start

Visit http://localhost:6006

Usage - production

Available on npm - @bbc/react-transcript-editor

npm install @bbc/react-transcript-editor

import TranscriptEditor from "@bbc/react-transcript-editor";

Minimal data needed for initialization

<TranscriptEditor
  transcriptData={someJsonFile}
  mediaUrl={"https://download.ted.com/talks/KateDarling_2018S-950k.mp4"}
/>

With more attributes

<TranscriptEditor
  transcriptData={someJsonFile}
  mediaUrl={"https://download.ted.com/talks/KateDarling_2018S-950k.mp4"}
  handleAutoSaveChanges={this.handleAutoSaveChanges}
  autoSaveContentType={'digitalpaperedit'}
  isEditable={true}
  spellCheck={false}
  sttJsonType={"bbckaldi"}
  handleAnalyticsEvents={this.handleAnalyticsEvents}
  fileName={"ted-talk.mp4"}
  title={"Ted Talk"}
  ref={this.transcriptEditorRef}
  mediaType={'video'}
/>
Attributes Description required type
transcriptData Transcript json yes Json
mediaUrl string url to media file - audio or video yes String
handleAutoSaveChanges returns content of transcription after a change no Function
autoSaveContentType specify the file format for data returned by handleAutoSaveChanges,falls back on sttJsonType. or draftjs no string
isEditable set to true if you want to be able to edit the text no Boolean
spellCheck set to true if you want the browser to spell check this transcript no Boolean
handleAnalyticsEvents if you want to collect analytics events. no Function
fileName used for saving and retrieving local storage blob files no String
title defaults to empty string no String
ref if you want to have access to internal functions such as retrieving content from the editor. eg to save to a server/db. no React ref
mediaType can be audio or video, if not provided the component uses the url file type to determine and adjust use of the page layout no String

See ./demo/app.js demo as a more detailed example usage of the component.

Note: fileName it is optional but it's needed if working with user uploaded local media in the browser, to be able to save and retrieve from local storage. For instance if you are passing a blob url to mediaUrl using createObjectURL this url is randomly re-generated on every page refresh so you wouldn't be able to restore a session, as mediaUrl is used as the local storage key. See demo app for more detail example of this./src/index.js

Note: mediaType if not defined, the component uses the url to determine the type and adjust the layout accordingly, however this could result in a slight delay when loading the component as it needs to fetch the media to determine it's file type

Typescript projects

If using in a parent project where typescript is being used you might need to add //@ts-ignore before the import statment like this

//@ts-ignore
import { TranscriptEditor } from "@bbc/react-transcript-editor";

Internal components

You can also import some of the underlying React components directly.

  • TranscriptEditor

  • TimedTextEditor

  • MediaPlayer

  • VideoPlayer

  • Settings

  • KeyboardShortcuts

  • ProgressBar

  • PlaybackRate

  • PlayerControls

  • RollBack

  • Select

To import the components you can do as follows

import TimedTextEditor from "@bbc/react-transcript-editor/TimedTextEditor";
import { TimedTextEditor } from "@bbc/react-transcript-editor";

However if you are not using TranscriptEditor it is recommended to follow the second option and import individual components like: @bbc/react-transcript-editor/TimedTextEditor rather than the entire library. Doing so pulls in only the specific components that you use, which can significantly reduce the amount of code you end up sending to the client. (Similarly to how react-bootstrap works)

See the storybook for each component details on optional and required attributes.

You can also use this node modules as standalone

import exportAdapter from "@bbc/react-transcript-editor/exportAdapter";

Converts from draftJs json format to other formats

import sttJsonAdapter from "@bbc/react-transcript-editor/sttJsonAdapter";

Converts various stt json formats to draftJs

import {
  secondsToTimecode,
  timecodeToSeconds,
  shortTimecode
} from "@bbc/react-transcript-editor/timecodeConverter";

some modules to convert to and from timecodes

System Architecture

Documentation

There's a docs folder in this repository.

docs/notes contains dev notes on various aspects of the project.

docs/adr contains Architecture Decision Record.

An architectural decision record (ADR) is a document that captures an important architectural decision made along with its context and consequences.

We are using this template for ADR

There also QA testing docs to manual test the component before a major release, (QA testing does not require any technical knowledge).

Build

To transpile ./packages and create a build in the ./dist folder, run:

npm run build:component

Demo & storybook

http://localhost:6006

Build - storybook

To build the storybook as a static site

npm run build:storybook

Publish storybook & demo to github pages

This github repository uses github pages to host the storybook and the demo of the component

npm run deploy:ghpages

add to git, and push to origin master to update

Alternatively If you simply want to build the demo locally in the build folder then just

npm run build:storybook

you can then run this command to serve the static site locally

npm run build:storybook:serve

Tests

Test coverage using jest, to run tests

npm run test

During development you can use

npm run test:watch

Travis CI

On commit this repo uses the .travis.yml config tu run the automated test on travis CI.

Deployment

To push to npm - @bbc/react-transcript-editor

npm publish:public

This runs npm run build:component and npm publish --access public under the hood

Note that only README.md and the dist folders are published to npm.
