Crowdin JavaScript client  

The Crowdin JavaScript client is a lightweight interface to the Crowdin API that works in any JavaScript environment, including web browsers, workers in web browsers, extensions in web browsers or desktop applications, Node.js etc. It provides common services for making API requests.

Our API is a full-featured RESTful API that helps you to integrate localization into your development process. The endpoints that we use allow you to easily make calls to retrieve information and to execute actions needed.

Installation

npm

npm i @crowdin/crowdin-api-client

yarn

yarn add @crowdin/crowdin-api-client

Quick Start

Typescript

import { Client, Credentials, SourceFilesModel } from '@crowdin/crowdin-api-client';

// credentials
const credentials: Credentials = {
  token: 'personalAccessToken',
  organization: 'organizationName' // optional
};

// initialization of crowdin client
const {
  projectsGroupsApi,
  uploadStorageApi,
  sourceFilesApi,
  translationsApi
} = new Client(credentials);

// get project list
projectsGroupsApi.listProjects()
  .then(projects => console.log(projects))
  .catch(error => console.error(error));

// You can also use async/wait. Add `async` keyword to your outer function/method
async function getProjects() {
  try {
    const projects = await projectsGroupsApi.listProjects();
    console.log(projects);
  } catch (error) {
    console.error(error);
  }
}

// Create file with json content to translate
async function createFile() {
  const projectId = 123;
  const fileData = {
    title: 'Example',
    description: 'Some Text'
  };
  const storage = await uploadStorageApi.addStorage('file1.json', fileData);
  const file = await sourceFilesApi.createFile(projectId, {
    name: 'file1.json',
    title: 'Sample file',
    storageId: storage.data.id,
    type: 'json'
  });
  console.log(file);
}

// Download translations
async function downloadTranslations() {
  const projectId = 123;
  const fileId = 456;
  const language = 'de';
  const downloadLink = await translationsApi.buildProjectFileTranslation(
    projectId,
    fileId,
    {
      targetLanguageId: language
    }
  );
  const response = await fetch(downloadLink.data.url);

You can generate Personal Access Token in your Crowdin Account Settings.

List of projects with Fetch API

In addition if you use client in non-Node.js environment you might have a troubles with http calls. This client uses axios which internally uses http and https Node modules. So there is an option to use http client based on Fetch API (keep in mind that fetch should be available in global scope).

import { ProjectsGroups } from '@crowdin/crowdin-api-client';

const projectsGroupsApi = new ProjectsGroups(credentials, {
  httpClientType: 'fetch'
});

Or even pass your own http client as httpClient property which should implement HttpClient interface.

Fetch all records

It is possible to fetch all records from paginatable methods (where we have limit and offset in arguments).

import { ProjectsGroups } from '@crowdin/crowdin-api-client';

// initialization of ProjectsGroups
const projectsGroupsApi = new ProjectsGroups({
  token: 'personalAccessToken',
  organization: 'organizationName' // optional
});

// get all projects
projectsGroupsApi
  .withFetchAll()
  .listProjects()
  .then(projects => console.log(projects))
  .catch(error => console.error(error));

// get projects but not more than 1000
projectsGroupsApi
  .withFetchAll(1000)
  .listProjects()
  .then(projects => console.log(projects))
  .catch(error => console.error(error));

Retry configuration

There is a possibility to configure client invoke http calls with retry mechanism.

import { ProjectsGroups } from '@crowdin/crowdin-api-client';

const projectsGroupsApi = new ProjectsGroups(credentials, {
  retryConfig: {
    retries: 2, // amount of retries (gte 0)
    waitInterval: 100, // wait interval in ms between retries
    conditions: [ // array of conditions which will check if retry should not be applied
      {
        test(error) {
          return error.code === 40
        }
      }
    ]
  }
});

Exception handling

In case of error library will throw an Error based exception. This can either be a generic error with an error message and a code, or a validation error that additionally contains validation error codes.

const crowdin = require('@crowdin/crowdin-api-client');

const token = '';

const { translationsApi } = new crowdin.Client({ token });

async function test() {
  const project = 123;
  const dir = 456;
  try {
    const res = await translationsApi.buildProjectDirectoryTranslation(project, dir);
    console.log(JSON.stringify(res));
  } catch (e) {
    if (e instanceof crowdin.CrowdinValidationError) {
      console.log('Validation error');
    } else if (e instanceof crowdin.CrowdinError) {
      console.log('Generic error');
    }
    console.error(e);
  }
}

test();

Http request timeout

By default request timeout will vary on http client implementation and/or environment (e.g. fetch uses timeout configured by the browser).
But there is an option to set constant value:

const crowdin = require('@crowdin/crowdin-api-client');

const credentials = { token: 'token' };

const httpRequestTimeout = 60 * 1000; // 60 seconds

const client = new crowdin.Client(credentials, { httpRequestTimeout });

Over-The-Air Content Delivery

:dizzy: Recommended for translations delivery to your website or mobile application.

You can also use the Crowdin OTA Client JS library to send the translated content to your web apps via content delivery. Crowdin Content Delivery uses a CDN vault that mirrors your project’s translated content. The updated translations will become available to users much faster.

GraphQL API

This library also provides possibility to use GraphQL API (only for Crowdin Enterprise).

```javascript const crowdin = require('@crowdin/crowdin-api-client');

const client = new crowdin.Client({ token: '{token}', organization: '{organization}' });

const query = ` query { viewer { projec
