# Userfront Core JS library

The Userfront Core JavaScript library is intended for use in frontend applications.

The Core library can be used for the following:

- **Tokens**: read the user's access token to send to your backend
- **User info**: information about the currently logged in user
- **Authentication**: signup, login, logout, and password reset tasks; these are useful for building custom forms and auth flows.

## Docs

Full docs can be found in the Userfront guide:

https://userfront.com/docs/js.html

## Setup

Install by npm (or yarn):

```sh
npm install @userfront/core --save
```

Import and initialize the library:

```js
import Userfront from "@userfront/core";

Userfront.init("demo1234");
```

## Examples

```js
// Import and initialize Userfront core JS
import Userfront from "@userfront/core";
Userfront.init("demo1234");

// Send a login link
Userfront.sendLoginLink("[email protected]");

// Read the access token
Userfront.tokens.accessToken;

## Development

### Building

- `npm build`: build all library files

The build commands are split into two parts. `build` and `build:beta` both run these commands, which do not need to be run separately:

- `npm build:standard`: build the standard library files:
- ESM module `build/userfront-core.module.js`
- CJS module `build/userfront-core.js`
- UMD module `build/userfront-core.umd.js`
- Module with bundled dependencies, for import from CDN: `build/userfront-core.modern.mjs`
