— @zhaoworks/context

Isolated contexts to manage resources across a codebase and nothing more.

Installation

λ bun add @zhaoworks/context

Usage

import { Context } from '@zhaoworks/context';

const database = new Database();

const ApplicationContext = Context.create({
  database: database,
  users: new UserService(database)
});

// use: wraps a function so you have typed context from an callback function
const FetchUser = ApplicationContext.use(({ users }) => {
  const user = await users.fetch('123');

  console.log('User 123 is', user.name);
});

// apply: the `use` function can be applied later
ApplicationContext.apply(FetchUser, {
  users: new FakeUserService() // overrides: you can override resources in apply method.
});

// fetch: gets a resource from an context
ApplicationContext.fetch('database').connect();
