Define and implement core constructs such as Application and Component
npm install @loopback/coreLoopBack makes it easy to build modern applications that require complex
integrations.
- Fast, small, powerful, extensible core
- Generate real APIs with a single command
- Define your data and endpoints with OpenAPI
- No maintenance of generated code
``shell`
$ npm install --save @loopback/core
@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.
Since @loopback/core is decoupled from the listening server implementation,
LoopBack applications are now able to work with any component that provides this
functionality.
`ts
// 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
const grpc = await app.getServer
// 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')});GRPC server running on port: ${grpc.getSync('grpc.port')}
console.log();`
},
)();
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.
Run npm test` from the root folder.
