Advanced tools
Microframework is a minimalistic framework you can use with TypeScript and JavaScript.
Microframework is a simple tool that allows you to execute your modules in a proper order, helping you to organize bootstrap code in your application.
First, install the module:
npm i microframework
Second, create a simple "module" named expressModule
:
import {MicroframeworkBootstrapSettings} from "microframework";
export function expressModule(settings: MicroframeworkBootstrapSettings) {
// create express app
const app = express();
// register all routes, Routes are just routes that should be stored outside of this module
const routes: any = Routes;
Object.keys(routes).forEach(routePath => app.get(routePath, routes[routePath]));
// run application to listen on given port
app.listen(3000);
// your module also can return a promise
}
Create app.ts
and bootstrap a microframework and your express module:
import {bootstrapMicroframework} from "microframework";
import {expressModule} from "./expressModule";
bootstrapMicroframework([
expressModule
])
.then(() => console.log("Application is up and running."))
.catch(error => console.log("Application is crashed: " + error));
That's all. You can do same for other modules. Take a look on sample to understand better how concept of modules and their bootstrapping in microframework.
You can specify additional options to microframework.
logo
- Logo needs to be used before application launches. To use logo ansi-art module should be installed.showBootstrapTime
- If set to true then framework shows how much time was spend to bootstrap all modules.bootstrapTimeout
- Number of milliseconds to wait before framework will bootstrap all modules.Example of using settings:
import {bootstrapMicroframework} from "microframework";
bootstrapMicroframework({
config: {
logo: "MyApp",
showBootstrapTime: true,
bootstrapTimeout: 10
},
modules: [
expressModule,
// ...
]
})
.then(() => console.log("Application is up and running."))
.catch(error => console.log("Application is crashed: " + error));
Sometimes few modules need to communicate between each other and use shared data.
For such purpose you can store the data in settings
object passed to each module
and use stored data across all other modules. For example:
import {MicroframeworkBootstrapSettings} from "microframework";
export function expressModule(settings: MicroframeworkBootstrapSettings) {
// create express app
const app = express();
// register all routes, Routes are just routes that should be stored outside of this module
const routes: any = Routes;
Object.keys(routes).forEach(routePath => app.get(routePath, routes[routePath]));
// run application to listen on given port
app.listen(3000);
settings.setData("express_app", app);
}
And another modules can use data this way:
import {MicroframeworkBootstrapSettings} from "microframework";
export function socketIoModule(settings: MicroframeworkBootstrapSettings) {
const io = io();
io.useExpress(settings.getData("express_app"));
}
In the case if you want to shutdown running application you need to do following:
import {bootstrapMicroframework} from "microframework";
bootstrapMicroframework({
config: {
logo: "MyApp",
showBootstrapTime: true,
bootstrapTimeout: 10
},
modules: [
expressModule,
// ...
]
})
.then(framework => {
// do something before shutdown
// and shutdown everything
return framework.shutdown();
})
.then(() => {
// now everything is turned off
})
.catch(error => console.log("Application is crashed: " + error));
All modules which use resources should release them, for example:
export async function typeormModule(settings: MicroframeworkBootstrapSettings) {
const connection = await createConnection({
driver: {
type: "mysql",
host: "localhost",
username: "test",
password: "test",
database: "test"
}
});
settings.addShutdownHandler(() => connection.close());
}
