|
|
Alternative front-end for Google Translate, serving as a Free and Open Source translator with over a hundred languages available
|
|
|
|
|
|
## How does it work?
|
|
|
|
Inspired by projects like [NewPipe](https://github.com/TeamNewPipe/NewPipe), [Nitter](https://github.com/zedeus/nitter), [Invidious](https://github.com/iv-org/invidious) or [Bibliogram](https://git.sr.ht/~cadence/bibliogram), *Lingva* scrapes through Google Translate and retrieves the translation without directly accessing any Google-related service, preventing them from tracking.
|
|
|
|
For this purpose, *Lingva* is built, among others, with the following Open Source resources:
|
|
|
|
+ [Lingva Scraper](https://github.com/thedaviddelta/lingva-scraper), a Google Translate scraper built and maintained specifically for this project, which obtains all kind of information from this platform.
|
|
+ [TypeScript](https://www.typescriptlang.org/), the JavaScript superset, as the language.
|
|
+ [React](https://reactjs.org/) as the main front-end framework.
|
|
+ [Next.js](https://nextjs.org/) as the complementary React framework, that provides Server-Side Rendering, Static Site Generation or serverless API endpoints.
|
|
+ [ChakraUI](https://chakra-ui.com/) for the in-component styling.
|
|
+ [Jest](https://jestjs.io/), [Testing Library](https://testing-library.com/) & [Cypress](https://www.cypress.io/) for unit, integration & E2E testing.
|
|
+ [Apollo Server](https://www.apollographql.com/docs/apollo-server/) for handling the GraphQL endpoint.
|
|
+ [Inkscape](https://inkscape.org/) for designing both the logo and the banner.
|
|
|
|
|
|
## Deployment
|
|
|
|
As *Lingva* is a [Next.js](https://nextjs.org/) project you can deploy your own instance anywhere Next is supported.
|
|
|
|
The only requirement is to set an environment variable called `NEXT_PUBLIC_SITE_DOMAIN` with the domain you're deploying the instance under. This is used for the canonical URL and the meta tags.
|
|
|
|
Optionally, there are other environment variables available:
|
|
+ `NEXT_PUBLIC_FORCE_DEFAULT_THEME`: Force a certain theme over the system preference set by the user. The accepted values are `light` and `dark`.
|
|
+ `NEXT_PUBLIC_DEFAULT_SOURCE_LANG`: Set an initial *source* language instead of the default `auto`.
|
|
+ `NEXT_PUBLIC_DEFAULT_TARGET_LANG`: Set an initial *target* language instead of the default `en`.
|
|
|
|
### Docker
|
|
|
|
An [official Docker image](https://hub.docker.com/r/thedaviddelta/lingva-translate) is available to ease the deployment using Compose, Kubernetes or similar technologies. Remember to also include the environment variables (simplified to `site_domain`, `force_default_theme`, `default_source_lang` and `default_target_lang`) when running the container.
|
|
|
|
#### Docker Compose:
|
|
|
|
```
|
|
version: '3'
|
|
|
|
services:
|
|
|
|
lingva:
|
|
container_name: lingva
|
|
image: thedaviddelta/lingva-translate:latest
|
|
restart: unless-stopped
|
|
environment:
|
|
- site_domain=lingva.ml
|
|
- force_default_theme=light
|
|
- default_source_lang=auto
|
|
- default_target_lang=en
|
|
ports:
|
|
- 3000:3000
|
|
```
|
|
|
|
#### Docker Run
|
|
|
|
```bash
|
|
docker run -p 3000:3000 -e site_domain=lingva.ml -e force_default_theme=light -e default_source_lang=auto -e default_target_lang=en thedaviddelta/lingva-translate:latest
|
|
```
|
|
|
|
### Vercel
|
|
|
|
Another easy way is to use the Next.js creators' own platform, [Vercel](https://vercel.com/), where you can deploy it for free with the following button.

|
## Public APIs
|
|
|
|
Nearly all the *Lingva* instances should supply a pair of public developer APIs: a RESTful one and a GraphQL one.
|
|
|
|
*Note: both APIs return the translation audio as a `Uint8Array` (served as `number[]` in JSON and `[Int]` in GraphQL) with the contents of the audio buffer.*
|
|
|
|
### REST API v1
|
|
|
|
+ GET `/api/v1/:source/:target/:query`
|
|
```typescript
|
|
{
|
|
translation: string
|
|
info?: TranslationInfo
|
|
}
|
|
```
|
|
|
|
+ GET `/api/v1/audio/:lang/:query`
|
|
```typescript
|
|
{
|
|
audio: number[]
|
|
}
|
|
```
|
|
|
|
+ GET `/api/v1/languages/?:(source|target)`
|
|
```typescript
|
|
{
|
|
languages: [
|
|
{
|
|
code: string,
|
|
name: string
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
In addition, every endpoint can return an error message with the following structure instead.
|
|
```typescript
|
|
{
|
|
error: string
|
|
}
|
|
```
|
|
|
|
### GraphQL API
|
|
|
|
+ `/api/graphql`
|
|
```graphql
|
|
query {
|
|
translation(source: String target: String query: String!) {
