    @loopback/core

    LoopBack makes it easy to build modern applications that require complex integrations.

    Overview

    • Fast, small, powerful, extensible core
    • Generate real APIs with a single command
    • Define your data and endpoints with OpenAPI
    • No maintenance of generated code

    Installation

    $ npm install --save @loopback/core

    Basic Use

    @loopback/core provides the foundation for your LoopBack app, but unlike previous versions, it no longer contains the implementation for listening servers.

    For a typical example of how to create a REST server with your application, see the @loopback/rest package.

    Advanced Use

    Since @loopback/core is decoupled from the listening server implementation, LoopBack applications are now able to work with any component that provides this functionality.

    // index.ts
    import {Application} from '@loopback/core';
    import {RestComponent} from '@loopback/rest';
    import {GrpcComponent} from '@loopback/grpc';
    
    const app = new Application({
      rest: {
        port: 3000,
      },
      grpc: {
        port: 3001,
      },
    });
    app.component(RestComponent); // REST Server
    app.component(GrpcComponent)(
      // GRPC Server
    
      async function start() {
        // Let's retrieve the bound instances of our servers.
        const rest = await app.getServer<RestServer>('RestServer');
        const grpc = await app.getServer<GrpcServer>('GrpcServer');
    
        // Define all sorts of bindings here to pass configuration or data
        // between your server instances, define controllers and datasources for them,
        // etc...
        await app.start(); // This automatically spins up all your servers, too!
        console.log(`REST server running on port: ${rest.getSync('rest.port')}`);
        console.log(`GRPC server running on port: ${grpc.getSync('grpc.port')}`);
      },
    )();

    In the above example, having a GRPC server mounted on your Application could enable communication with other GRPC-enabled microservices, allowing things like dynamic configuration updates.
