@userfront/core v0.6.8

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:

Setup

Install by npm (or yarn):

npm install @userfront/core --save

Import and initialize the library:

import Userfront from "@userfront/core";

Userfront.init("demo1234");

Examples

// Import and initialize Userfront core JS
import Userfront from "@userfront/core";

Development

Building

• npm build: increment patch version & build all library files
• npm build:beta: increment prerelease version & 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
• npm build:ie11: build the IE11-compatible library file: userfront-core.ie11.umd.js
  • This script applies a patch to microbundle to enable Babel transformation of dependencies, so that Promises from axios are polyfilled without needing to touch the global Promise object.
