## You should not use this package directly for usage in the web browser
If you use Tolgee on the web, use [@tolgee/web](https://github.com/tolgee/tolgee-js/tree/main/packages/web) package, which extends this package with web-related functionality.
This package is platform-agnostic, so it contains only the most general functionality.
## Installation
```
npm install @tolgee/core
```
## Usage
First, create a Tolgee instance and run it.
```ts
import { TolgeeCore } from "@tolgee/core";
const tg = TolgeeCore()
.use(...)
.init(...)
tg.run();
```
To learn more, check [the docs](https://tolgee.io/js-sdk/5.0.0-alpha.1/).

## Development
We welcome your PRs.
To develop the package locally:
1. Clone [the repository](https://github.com/tolgee/tolgee-js)
1. Install the packages in the repository root
```
pnpm install
```
1. Run web or any integration development script
```
pnpm develop:react
```
or
```
pnpm develop:web
```
This runs the development suite of this monorepo for the specific integration. The changes in each dependency package are
automatically built and propagated to the test application, which you can open and play within the browser.
### Testing
To run Jest tests of this package, execute
```
npm run test
```
In the `/packages/core` directory.
### End-to-end (e2e) testing
Each integration is end-to-end tested via cypress. The tests are defined in `/e2e/cypress/e2e` directory.
To run the e2e tests, run
```
pnpm run e2e run
```
E.g.
```
pnpm run e2e run web
```
To open and play with e2e tests, run:
```
pnpm run e2e open
```
