Introduction

Typed Chrome Webstore API to upload/publish extensions and downloading crx file

Installation

npm install typed-chrome-webstore-api

How to use

See https://developer.chrome.com/webstore/using_webstore_api to understand methods meaning and know how to get client_id, client_secret and refresh_token strings needed for authentication.

To work with Webstore API you need to get token first:

const fetchToken = require('typed-chrome-webstore-api').fetchToken;
const token = fetchToken('clientId', 'clientSecret', 'refreshToken');

Then create WebstoreApi instance initialized with token:

const WebstoreApi = require('typed-chrome-webstore-api').WebstoreApi;
const api = new WebstoreApi(token);

Upload new extension

// Any Readable stream or Buffer
const zip = fs.createReadStream('./mypackage.zip');
// Result format is defined as IWebstoreResource in d.ts file 
const result = await api.upload(zip);

Upload existed extension

appId is the ID of the existing Web Store item (could be found in admin panel)

// Any Readable stream or Buffer
const zip = fs.createReadStream('./mypackage.zip');
// Result format is defined as IWebstoreResource in .d.ts file 
const result = await api.upload(zip, appId);

Check uploaded app/extension status

// Result format is defined as IWebstoreResource in .d.ts file 
const result = await api.get(appId);

Publish item

// 'default' or 'trustedTesters', defined in PublishTarget enum in .d.ts file
const target = 'default';
// Result format is defined as IPublishResponse in .d.ts file 
const result = await api.publish(appId, target);

Be aware of API's undocumented behaviour. For example, extension had a version = '1.10.0' Then we successfully published a new one with version = '1.20.0' (status = 'OK') 'get upload' request returns version '1.20.0' after it. But this version is still in publishing progress Now we are publishing '1.30.0' but 'publish' and request fails with 500 error, but (!) actually Our version have been accepted, and after some time out extension increases it's version to '1.30.0'!

Get Licenses

const result = await api.getLicenses(appId, userId);

Get User Licenses

const result = await api.getUserLicenses(appId);

Get Payments

const result = await api.getPayments(itemId);

Download extension crx

This feature is experimental because of API is not documented

// A bit ugly, looks better if you use TypeScript :)
const downloadCrx = require('typed-chrome-webstore-api').DownloadCrx.downloadCrx;
const fs = require('fs');

const fstream = fs.createWriteStream('file.crx');
const readStream = await downloadCrx('extensionId');
readStream.pipe(fstream);

downloadCrx() also accepts additional options, look at downloadCrx.d.ts file for details
