How to use Boba.js

Boba.js is a lightweight JavaScript library that helps developers build web applications by providing dependency injection and inversion of control. Here are the steps to use Boba.js for your next project.

1. Installation: You can install Boba.js using npm, yarn or download the latest version from GitHub.

   npm install boba.js
   

2. Configuration: Once installed, you need to configure Boba.js in your application. You can do this by importing it into your main JavaScript file and creating a new instance of the

   Container
   class. The container is where you register your dependencies and specify their configurations, including their lifetime scopes.

   import { Container } from 'boba.js';
   
   const container = new Container();
   

3. Registering Dependencies: After configuring the container, you can now start registering your application dependencies. You can use the

   register
   method of the container instance to add new services.

   container.register('logger', () => new Logger());
   

4. Resolving Dependencies: To use the registered services, you can call them directly from the container using the

   resolve
   method.

   const logger = container.resolve('logger');
   logger.log('Hello World!');
   

5. Dependency Injection: Boba.js also supports dependency injection, which allows you to pass dependencies to classes or functions automatically. For example, if you have a class that depends on a logger service, you can inject the logger service into the constructor of the class.

   class MyClass {
     constructor(logger) {
       this.logger = logger;
     }
   
     doSomething() {
       this.logger.log('Doing something...');
     }
   }
   
   const myClassInstance = container.resolve('myClass');
   myClassInstance.doSomething();
   

6. Lifetime Scopes: Boba.js provides different lifetime scopes for registered services. You can choose between Transient, Singleton and Scoped lifetimes. Transient services are created every time they are resolved, Singleton services are created once per application instance and Scoped services are created once per scope.

   container.register('logger', () => new Logger(), { lifetime: 'singleton' });
   

7. Cleaning Up: Finally, when your application is shutting down, you should clean up the container by calling its

   dispose
   method.

   container.dispose();
   

That's it! These are the basic steps to use Boba.js in your web application. With Boba.js, you can easily manage and organize your dependencies and focus on building great features for your users.
