Entry Point

Plumier application is the entry point of all Plumier based API. Creating Plumier application simply by creating instance of Plumier class. The simplest Plumier application at least must have WebApiFacility installed like below.

import Plumier from "plumier"
new Plumier()
.set(new WebApiFacility())

By default Plumier will search for controllers using this glob pattern ./**/*controller.+(ts|js) or ./**/*entity.+(ts|js), its mean it will search for all TypeScript/JavaScript files ends with controller or entity (for first class entity). It also automatically detected exported controller in the same file with the entry point file, this is useful for single file project.

Above configuration does noting because no controller specified. We can start above code using ts-node or ts-node-dev, by specify it on the package.json script like below.

"name": "my-cool-api",
"version": "1.0.0",
"scripts": {
"debug": "ts-node-dev --inspect -- src/index",
"build": "tsc",
"start": "node src/index"
"dependencies": {
"plumier": "^1.0.0-rc.7",
"devDependencies": {
"ts-node-dev": "^1.1.1",
"typescript": "^4.1.3",


Plumier application is configurable using facility, facility is a framework component consist of configurations, ordered middlewares and some micro process before the framework started.

There are list of built-in facility that ready to be used.

Application For Testing#

When Plumier listen method called immediately its make Plumier lost its ability for testing purpose. To do that you can use initialize method to get a testable server like below.

import Plumier, { Configuration, WebApiFacility } from "plumier"
function createApp(config?: Partial<Configuration>) {
return new Plumier()
// specify the rootDir since it will be executed in different directory (test dir)
.set({ ...config, rootDir: __dirname })
.set(new WebApiFacility())
export default createApp

By using code above, you can test your API using supertest like below.

import createApp from "../src/app"
import supertest from "supertest"
it("Should serve API properly", async () => {
const app = await createApp({ mode: "production" })
await supertest(app.callback())
