@lokalise/node-api

What is @lokalise/node-api?

@lokalise/node-api is an official Node.js client for the Lokalise API, which allows developers to interact with the Lokalise platform programmatically. Lokalise is a translation management system that helps teams manage localization projects. This package provides a way to automate tasks such as managing projects, uploading and downloading files, and handling translations.

What are @lokalise/node-api's main functionalities?

Managing Projects

This feature allows you to create and manage projects on Lokalise. The code sample demonstrates how to create a new project with a specified name, description, and languages.

const LokaliseApi = require('@lokalise/node-api');
const lokaliseApi = new LokaliseApi({ apiKey: 'your_api_key' });

async function createProject() {
  const project = await lokaliseApi.projects.create({
    name: 'New Project',
    description: 'A new project description',
    languages: [{ lang_iso: 'en' }]
  });
  console.log(project);
}

createProject();

Uploading Files

This feature allows you to upload translation files to a specific project. The code sample demonstrates how to upload a file by providing the project ID, base64 encoded file content, filename, and language ISO code.

const LokaliseApi = require('@lokalise/node-api');
const lokaliseApi = new LokaliseApi({ apiKey: 'your_api_key' });

async function uploadFile() {
  const upload = await lokaliseApi.files.upload('project_id', {
    data: 'base64_encoded_file_content',
    filename: 'translations.json',
    lang_iso: 'en'
  });
  console.log(upload);
}

uploadFile();

Downloading Files

This feature allows you to download translation files from a specific project. The code sample demonstrates how to download files by providing the project ID and specifying the format and whether to use original filenames.

const LokaliseApi = require('@lokalise/node-api');
const lokaliseApi = new LokaliseApi({ apiKey: 'your_api_key' });

async function downloadFile() {
  const download = await lokaliseApi.files.download('project_id', {
    format: 'json',
    original_filenames: true
  });
  console.log(download);
}

downloadFile();

Handling Translations

This feature allows you to handle translations within a project. The code sample demonstrates how to add a new translation key with its corresponding translations by providing the project ID, key name, and translations.

const LokaliseApi = require('@lokalise/node-api');
const lokaliseApi = new LokaliseApi({ apiKey: 'your_api_key' });

async function addTranslation() {
  const translation = await lokaliseApi.keys.create('project_id', {
    keys: [{
      key_name: 'welcome_message',
      translations: [{
        language_iso: 'en',
        translation: 'Welcome!'
      }]
    }]
  });
  console.log(translation);
}

addTranslation();

Other packages similar to @lokalise/node-api

i18next

i18next is a popular internationalization framework for JavaScript. It provides a complete solution for localizing applications, including support for translation files, language detection, and interpolation. Compared to @lokalise/node-api, i18next focuses more on the client-side implementation of localization rather than managing translation projects.

gettext-parser

gettext-parser is a library for parsing and compiling gettext files (PO and MO files). It is useful for applications that use gettext for localization. While @lokalise/node-api provides a comprehensive API for managing translation projects on Lokalise, gettext-parser is more focused on handling gettext file formats.

node-polyglot

node-polyglot is a lightweight internationalization library for Node.js. It provides a simple way to manage translations and supports interpolation and pluralization. Compared to @lokalise/node-api, node-polyglot is more suitable for small-scale localization needs and does not offer project management features.

Getting started

Installation

This library has no special requirements. Install it with NPM:

npm install @lokalise/node-api

Initializing Client

In order to perform API requests, you require a special token that can be obtained in your personal profile (API tokens section). Note that the owner of the token must have admin access rights.

After you've obtained the token, initialize the client:

const { LokaliseApi } = require('@lokalise/node-api');

const lokaliseApi = new LokaliseApi({ apiKey: '<apiKey>'});

Now you may perform API requests, for example:

const projects = lokaliseApi.projects.list();
projects[0].name;

All object attributes may be found in the interfaces.

Branching

If you are using project branching feature, simply add branch name separated by semicolon to your project ID in any endpoint to access the branch. For example, in order to access new-feature branch for the project with an id 123abcdef.01:

lokaliseApi.files.list({project_id: '123abcdef.01:new-feature'});

Pagination

Bulk fetches support pagination. There are two common parameters available:

• limit (defaults to 100, maximum is 5000) - number of records to display per page
• page (defaults to 1) - page to fetch

For instance:

lokaliseApi.translationProviders.list({team_id: team_id, page: 2, limit: 10});

Usage

Every request returns a promise with a corresponding object (or array of objects) as the result.

Additional Info

Error handling

Error codes are listed in the API docs.

API Rate Limits

Lokalise does not rate-limit API requests, however retain a right to decline the service in case of excessive use. Only one concurrent request per token is allowed. To ensure data consistency, it is not recommended to access the same project simultaneously using multiple tokens.

Running Tests

This library is tested with Node 8, 9, 10, 11, 12, and 13. To test it locally:

1. Copypaste .env.example file as .env. Put your API token inside. The .env file is excluded from version control so your token is safe. All in all, we use pre-recorded cassettes, so the actual API requests won't be sent. However, providing at least some token is required.
2. Run npm test. Observe test results and coverage.

Building

1. Run npm run-script build
2. Browse dist/ folder
