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* scrappes through GTranslate and retrieves the translation without using any Google-related service, preventing them from tracking.

For this purpose, *Lingva* is built, among others, with the following Open Source resources:

+ [TypeScript](https://www.typescriptlang.org/), the JavaScript superset, as the language.
+ [React](https://reactjs.org/) as the main front-end framework.
+ [NextJS](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 [NextJS](https://nextjs.org/) project you can deploy your own instance anywhere Next is supported.

The only requerement 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.

The easiest way is to use their 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

+ `/api/v1/:source/:target/:query`
```typescript
{
    translation?: string,
    errorMsg?: string
}
```

+ `/api/v1/audio/:lang/:query`
```typescript
{
    audio?: number[],
    errorMsg?: string
}
```

### GraphQL API

+ `/api/graphql`
```graphql
query {
    translation(source: String target: String query: String!) {
        source: {
            lang: String!
            text: String
            audio: [Int]
        }
        target: {
            lang: String!
            text: String
            audio: [Int]
        }
    }
    audio(lang: String query: String!) {
        lang: String!
        text: String
        audio: [Int]
    }
}
```
