        # Shotstack NodeJS SDK 

Node SDK for [Shotstack](http://shotstack.io), the cloud video editing API.

Shotstack is a cloud based video editing platform that enables the editing of videos using code.

The platform uses an API and a JSON format for specifying how videos should be edited and what assets and titles should be used.

A server based render farm takes care of rendering the videos allowing multiple videos to be created simultaneously.

For examples of how to use the SDK to create videos using code checkout the Node demo repo: https://github.com/shotstack/node-demos

# Using the Node SDK

### Installation

```bash

npm install shotstack-sdk

```

## Video Editing

The Shotstack SDK enables programmatic video editing via the Edit API `render` endpoint. Prepare JSON edits using the

provided schema classes and `POST` to the API for rendering.

### Video Editing Example

The example below trims the start of a video clip and plays it for 8 seconds. The edit is prepared using the SDK models

and then sent to the API for rendering.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.EditApi();

let videoAsset = new Shotstack.VideoAsset;

videoAsset

    .setSrc('https://s3-ap-southeast-2.amazonaws.com/shotstack-assets/footage/skater.hd.mp4')

    .setTrim(3)

let videoClip = new Shotstack.Clip;

videoClip

    .setAsset(videoAsset)

    .setStart(0)

    .setLength(8);

let track = new Shotstack.Track;

track.setClips([videoClip]);

let timeline = new Shotstack.Timeline;

timeline.setTracks([track]);

let output = new Shotstack.Output;

output

    .setFormat('mp4')

    .setResolution('sd');

let edit = new Shotstack.Edit;

edit

    .setTimeline(timeline)

    .setOutput(output);

api.postRender(edit).then((data) => {

    console.log(data.response.id);

});

```

### Status Check Example

The example request below can be called a few seconds after the render above is posted. It will return the status of 

the render, which can take several seconds to process.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.EditApi();

const id = '75143ec6-4b72-46f8-a67a-fd7284546935'; // use the render id from previous example

api.getRender(id, { data: false, merged: true }).then((data) => {

    if (data.response.status === 'done') {

        console.log(data.response.url);

    }

});

```

### Save a Template Example

The example below uses the Edit we create in the [Video Editing Example](#video-editing-example) and saves it as a

template. The template can be rendered at a later date and can include placeholders. Placeholders can be replaced 

when rendered using [merge fields](#mergefield).

This example uses a placeholder for the video src (URL), trim (TRIM), and length (LENGTH) to allow you to trim any video

using a template.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.EditApi();

let videoAsset = new Shotstack.VideoAsset;

videoAsset

    .setSrc('{{ URL }}')

    .setTrim('{{ TRIM }}');

let videoClip = new Shotstack.Clip;

videoClip

    .setAsset(videoAsset)

    .setStart(0)

    .setLength('{{ LENGTH }}');

let track = new Shotstack.Track;

track.setClips([videoClip]);

let timeline = new Shotstack.Timeline;

timeline.setTracks([track]);

let output = new Shotstack.Output;

output

    .setFormat('mp4')

    .setResolution('sd');

let edit = new Shotstack.Edit;

edit

    .setTimeline(timeline)

    .setOutput(output);

const template = new Shotstack.Template;

template

    .setName('Trim Template')

    .setTemplate(edit);

api.postTemplate(template).then((data) => {

    console.log(data.response.id);

});

```

### Render a Template Example

The example below renders the template we created in the previous example and includes merge fields that will replace

the placeholders. Once submitted use the returned render ID and call the [Status Check Example](#status-check-example)

to get the render progress.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.EditApi();

const id = '8aeabb0e-b5eb-8c5e-847d-82297dd4802a'; // use the template id from previous example

const mergeFieldUrl = new Shotstack.MergeField;

mergeFieldUrl

    .setFind('URL')

    .setReplace('https://s3-ap-southeast-2.amazonaws.com/shotstack-assets/footage/skater.hd.mp4');

const mergeFieldTrim = new Shotstack.MergeField;

mergeFieldTrim

    .setFind('TRIM')

    .setReplace(3);

const mergeFieldLength = new Shotstack.MergeField;

mergeFieldLength

    .setFind('LENGTH')

    .setReplace(6);

const template = new Shotstack.TemplateRender;

template

    .setId(id)

    .setMerge([

        mergeFieldUrl,

        mergeFieldTrim,

        mergeFieldLength,

    ]);

api.postTemplateRender(template).then((data) => {

    console.log(data.response.id);

});

```

## Video Editing Schemas

The following schemas are used to prepare a video edit.

### Edit

An **Edit** defines the arrangement of a video on a timeline, an audio edit or an image design and the output format.

#### Example:

```javascript

const Shotstack = require('shotstack-sdk');

const edit = new Shotstack.Edit;

edit

  .setTimeline(timeline)

  .setOutput(output)

  .setMerge(merge)

 The motion effect speed can also be controlled by appending `Fast` or `Slow` to the effect, e.g. `zoomInFast` or `slideRightSlow`.| -

setFilter(string filter) | A filter effect to apply to the Clip. 

`boost` - boost contrast and saturation

`contrast` - increase contrast

`darken` - darken the scene

`greyscale` - remove colour

`lighten` - lighten the scene

  .setThumbnail(thumbnail)

  .setDestinations(destinations);

```

#### Methods:

Method | Description | Required

:--- | :--- | :---: 

setFormat(string format) | The output format and type of media file to generate. 


`mp4` - mp4 video file

`gif` - animated gif

`jpg` - jpg image file

`png` - png image file

`bmp` - bmp image file

`mp3` - mp3 audio file (audio only)

 | Y

setResolution(string resolution) | The output resolution of the video or image.

`hd` - 1280px x 720px @ 25fps

`1080` - 1920px x 1080px @ 25fps

 | -

setAspectRatio(string aspectRatio) | The aspect ratio (shape) of the video or image. Useful for social media output formats. Options are: 

`16:9` - regular landscape/horizontal aspect ratio (default)

`9:16` - vertical/portrait aspect ratio

`1:1` - square aspect ratio

`4:5` - short vertical/portrait aspect ratio

`4:3` - legacy TV aspect ratio

 | -

setSize([Shotstack.Size](#size) size) | Set a custom size for a video or image. When using a custom size omit the `resolution` and `aspectRatio`. Custom sizes must be divisible by 2 based on the encoder specifications. | -

setFps(float fps) | Override the default frames per second. Useful for when the source footage is recorded at 30fps, i.e. on  mobile devices. Lower frame rates can be used to add cinematic quality (24fps) or to create smaller file size/faster render times or animated gifs (12 or 15fps). Default is 25fps. 

`12` - 12fps

`15` - 15fps

`23.976` - 23.976fps

`low` - slightly reduced quality, smaller file size

`medium` - optimized quality, render speeds and file size

`high` - slightly increased quality, larger file size

 | -

setRepeat(bool repeat) | Loop settings for gif files. Set to `true` to loop, `false` to play only once. [default to `true`] | -

## Inspecting Media

The SDK `probe` endpoint can be used to inspect media hosted online. Simply pass the URL of an asset to inspect.

### Probe Example

The example below inspects (probes) a video hosted on GitHub and returns metadata about the file.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.EditApi();

const url = 'https://github.com/shotstack/test-media/raw/main/captioning/scott-ko.mp4';

api.probe(url).then((data) => {

    data.response.metadata.streams.forEach(stream => {

        if (stream.codec_type === 'video') {

            console.log('Example settings for: ' + data.response.metadata.format.filename);

            console.log('Width: ' + stream.width + 'px');

            console.log('Height: ' + stream.height + 'px');

            console.log('Framerate: ' + stream.r_frame_rate + ' fps');

            console.log('Duration: ' + stream.duration + ' secs');

        }

    });

});

```

## Probe Schemas

The following schemas are returned by the probe request.

### ProbeResponse

The **ProbeResponse** is the response returned after a [probe request](https://shotstack.io/docs/api/#inspect-media) is submitted. The probe requests returns data from FFprobe formatted as JSON.

#### Methods:

Method | Description | Required

:--- | :--- | :---: 

getSuccess(): bool | `true` if media successfully read, else `false`. | Y

getMessage(): string | `Created`, `Bad Request` or an error message. | Y

getResponse(): object | The response from FFprobe in JSON format | Y

## Managing Assets

By default, all assets generated by the editing API are hosted by Shotstack and served via our CDN. The SDK provides

access to the Serve API to retrieve information about hosted files. Files can also be deleted.

### Assets by Render ID Example

The example below uses a render ID to look up hosted assets associated with the render. Note that multiple assets can be

created for a render, i.e. video, thumb and poster. Each asset has a unique asset ID different to the render ID.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.ServeApi();

const id = '140924c6-077d-4334-a89f-94befcfc0155'; // Use a valid render ID

api.getAssetByRenderId(id).then((assets) => {

    assets.data.forEach((asset) => {

        if (asset.attributes.status === 'ready') {

            console.log('>> Asset CDN URL: ' + asset.attributes.url);

            console.log('>> Asset ID: ' + asset.attributes.id);

            console.log('>> Render ID: ' + asset.attributes.renderId);

        }

    });

});

```

### Assets by Asset ID Example

Every asset has a unique asset ID, the example below looks up an asset by its asset ID.

```javascript

const Shotstack = require('shotstack-sdk');

const defaultClient = Shotstack.ApiClient.instance;

defaultClient.basePath = 'https://api.shotstack.io/stage';

const DeveloperKey = defaultClient.authentications['DeveloperKey'];

DeveloperKey.apiKey = 'H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD'; // use the correct API key

const api = new Shotstack.ServeApi();

const id = 'ed43eae3-4825-4c03-979d-f7dc47b9997c'; // use a valid asset ID

api.getAsset(id).then((asset) => {

    if (asset.data.attributes.status === 'ready') {

        console.log('>> Asset CDN URL: ' + asset.data.attributes.url);

        console.log('>> Asset ID: ' + asset.data.attributes.id);

        console.log('>> Render ID: ' + asset.data.attributes.renderId);

    }

});

```

## Asset Schemas

The following schemas are returned by requests to the Serve API.

### AssetResponse

The **AssetResponse** is the response returned by the Serve API [get asset](https://shotstack.io/docs/api/#get-asset) request. Includes details of a hosted video, image, audio file, thumbnail or poster image. The response follows  the [json:api](https://jsonapi.org/) specification.

#### Methods:
