A **free** and **unlimited** API for Google Translate for Node.js.
**In version 9+ library was fully rewritten. For legacy documentation please see [legacy branch](https://github.com/vitalets/google-translate-api/tree/legacy).**
> DISCLAIMER!
To be 100% legal please use official [Google Translate API](https://cloud.google.com/translate). This project is mainly for pet projects and prototyping.

## Features
* auto language detection
* all [Google Translate languages](https://cloud.google.com/translate/docs/languages) supported
* react-native supported
* transliteration
## Installation
```
npm install @vitalets/google-translate-api
```
## Usage
### Node.js
```ts
import { translate } from '@vitalets/google-translate-api';
const { text } = await translate('Привет, мир! Как дела?', { to: 'en' });
console.log(text) // => 'Hello World! How are you?'
```
### React-native
Since react-native has [full support of fetch API](https://reactnative.dev/docs/network) translation works the same way as in Node.js.
### Web pages
This library **does not work inside web pages** because `translate.google.com` does not provide [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) headers allowing access from other domains.
### Browser extensions
Although library does not work in regular web pages it can be used in browser extensions.
Extensions background and popup pages are [not limited](https://developer.chrome.com/docs/extensions/mv3/xhr/) with same origin policy. To use translation API you should do the following:
1. Add host permissions to `manifest.json`:
```diff
+ "host_permissions": [
+ "https://translate.google.com/"
+ ]
```
2. Import `translate` as usual in background or popup script:
```js
// background.js
import { translate } from '@vitalets/google-translate-api';
const { text } = await translate('Привет мир');
console.log(text);
```
3. Bundle code (for example with `webpack`):
```js
// webpack.config.js
module.exports = {
mode: 'development',
entry: './background.js',
output: {
filename: 'bundle.js',
},
};
```
## Limits
Google Translate has request limits. If too many requests are made from the same IP address, you will get a **TooManyRequestsError** (code 429). You can use **proxy** to bypass it:
```ts
import { translate } from '@vitalets/google-translate-api';
import { HttpProxyAgent } from 'http-proxy-agent';
const agent = new HttpProxyAgent('http://103.152.112.162:80');
const { text } = await translate('Привет, мир!', {
to: 'en',
fetchOptions: { agent },
});
```
See [examples/with-proxy.ts] for more details.
> Available proxy list you can find [here](https://free-proxy-list.net/) (with `anonymous` in **Anonymity* and `yes` in *Google* columns).
Common pattern for selecting proxy is following:
```ts
try {
const { text } = await translate('Привет, мир!', {
to: 'en',
fetchOptions: { agent },
});
} catch (e) {
if (e.name === 'TooManyRequestsError') {
// retry with another proxy agent
}
}
```
See [#107](https://github.com/vitalets/google-translate-api/issues/107) for discussion.
