Project description

Typescript library to upload videos to api.video using delegated upload token (or usual access token) from the front-end.

It allows you to upload videos in two ways:

  • standard upload: to send a whole video file in one go
  • progressive upload: to send a video file by chunks, without needing to know the final size of the video file

Getting started

Installation

Installation method #1: requirejs

If you use requirejs you can add the library as a dependency to your project with

$ npm install --save @api.video/video-uploader

You can then use the library in your script:

// standard upload:
var { VideoUploader } = require('@api.video/video-uploader');

var uploader = new VideoUploader({
    // ... (see bellow)
}); 

// progressive upload:
var { ProgressiveUploader } = require('@api.video/video-uploader');

var uploader = new ProgressiveUploader({
    // ... (see bellow)
}); 

Installation method #2: typescript

If you use Typescript you can add the library as a dependency to your project with

$ npm install --save @api.video/video-uploader

You can then use the library in your script:

// standard upload:
import { VideoUploader } from '@api.video/video-uploader'

const uploader = new VideoUploader({
    // ... (see bellow)
});

// progressive upload:
import { ProgressiveUploader } from '@api.video/video-uploader'

const uploader = new ProgressiveUploader({
    // ... (see bellow)
});

Simple include in a javascript project

Include the library in your HTML file like so:

<head>
    ...
    <script src="https://unpkg.com/@api.video/video-uploader" defer></script>
</head>

Then, once the window.onload event has been trigered, create your player using new VideoUploader():

...
<form>
    <input type="file" id="input" onchange="uploadFile(this.files)">
</form>
<script type="text/javascript">
    function uploadFile(files) {
        new VideoUploader({
            file: files[0],
            uploadToken: "YOUR_DELEGATED_TOKEN"
        }).upload();
    }
</script>

Instanciation

Options

The upload library is instanciated using an options object. Options to provide depend on the way you want to authenticate to the API: either using a delegated upload token (recommanded), or using a usual access token.

Using a delegated upload token (recommended):

Using delegated upload tokens for authentication is best options when uploading from the client side. To know more about delegated upload token, read the dedicated article on api.video's blog: Delegated Uploads.

Option nameMandatoryTypeDescription
uploadTokenyesstringyour upload token
videoIdnostringid of an existing video
common options (see bellow)

Using an access token (discouraged):

Warning: be aware that exposing your access token client-side can lead to huge security issues. Use this method only if you know what you're doing :).

Option nameMandatoryTypeDescription
accessTokenyesstringyour access token
refreshTokennostringyour refresh token (please not that if you don't provide a refresh token, your upload may fails due to the access token lifetime of 60 minutes)
videoIdyesstringid of an existing video
common options (see bellow)

Using an API key (strongly discouraged):

Warning: be aware that exposing your API key client-side can lead to huge security issues. Use this method only if you know what you're doing :).

Common options

Option nameMandatoryTypeDescription
fileyesFilethe file you want to upload
chunkSizenonumbernumber of bytes of each upload chunk (default: 50MB, min: 5MB, max: 128MB)
apiHostnostringapi.video host (default: ws.api.video)
retriesnonumbernumber of retries when an API call fails (default: 5)

Example

    const uploader = new VideoUploader({
        file: files[0],
        uploadToken: "YOUR_DELEGATED_TOKEN",
        chunkSize: 1024*1024*10, // 10MB
        retries: 10,
    });

Methods

upload()

The upload() method starts the upload. It takes no parameter. It returns a Promise that resolves once the file is uploaded. If an API call fails more than the specified number of retries, then the promise is rejected.
On success, the promise embeds the video object returned by the API.
On fail, the promise embeds the status code & error message returned by the API.

Example

    // ... uploader instanciation

    uploader.upload()
        .then((video) => console.log(video))
        .catch((error) => console.log(error.status, error.message));

onProgress()

The onProgress() method let you defined an upload progress listener. It takes a callback function with one parameter: the onProgress events.
An onProgress event contains the following attributes:

  • uploadedBytes (number): total number of bytes uploaded for this upload
  • totalBytes (number): total size of the file
  • chunksCount (number): number of upload chunks
  • chunksBytes (number): size of a chunk
  • currentChunk (number): index of the chunk being uploaded
  • currentChunkUploadedBytes (number): number of bytes uploaded for the current chunk

Example

    // ... uploader instanciation
    
    uploader.onProgress((event) => {
        console.log(`total number of bytes uploaded for this upload: ${event.uploadedBytes}.`);
        console.log(`total size of the file: ${event.totalBytes}.`);
        console.log(`number of upload chunks: ${event.chunksCount} .`);
        console.log(`size of a chunk: ${event.chunksBytes}.`);
        console.log(`index of the chunk being uploaded: ${event.currentChunk}.`);
        console.log(`number of bytes uploaded for the current chunk: ${event.currentChunkUploadedBytes}.`);
    });

preventEmptyPartsnobooleanif true, the upload will succeed even if an empty Blob is passed to uploadLastPart(). This may alter performances a bit in some cases (default: false)

Example

    const uploader = new ProgressiveUploader({

        retries: 10,
    });

Methods

uploadPart(file: Blob)

The upload() method starts the upload. It takes no parameter. It returns a Promise that resolves once the file is uploaded. If an API call fails more than the specified number of retries, then the promise is rejected.
On success, the promise embeds the video object returned by the API.
On fail, the promise embeds the status code & error message returned by the API.

Example

    // ... uploader instanciation

    uploader.uploadPart(blob)
        .catch((error) => console.log(error.status, error.message));

uploadLastPart(file: Blob)

The upload() method starts the upload. It takes no parameter. It returns a Promise that resolves once the file is uploaded. If an API call fails more than the specified number of retries, then the promise is rejected.
On success, the promise embeds the video object returned by the API.
On fail, the promise embeds the status code & error message returned by the API.

Example

    // ... uploader instanciation

    uploader.uploadLastPart(blob)
        .then((video) => console.log(video))

An onProgress event contains the following attributes:

  • uploadedBytes (number): total number of bytes uploaded for this upload
  • totalBytes (number): total size of the file

Example

    // ... uploader instanciation
    
    uploader.onProgress((event) => {
        console.log(`total number of bytes uploaded for this upload: ${event.uploadedBytes}.`);
        console.log(`total size of the file: ${event.totalBytes}.`);
    });
