Appearance

@zept/http ​

Inspired by koa, only middleware is supported by default, but the handler of this framework is inspired by express, not koa. The concept of middleware is similar to express.

ts
const { ZeptServer } = require('@zept/http');
const server = new ZeptServer();

server.use((req, res, next) => {
  next();
});

server.listen(3000);
const { ZeptServer } = require('@zept/http');
const server = new ZeptServer();

server.use((req, res, next) => {
  next();
});

server.listen(3000);

Installation ​

Install using npm:

npm install @zept/http
npm install @zept/http

async/await ​

zept supports async/await by default.

ts
app.use(async (req, res, next) => {
  await next();
  console.log('2');
});

app.use(async (req, res) => {
  await new Promise((resolve) => {
    setTimeout(() => {
      resolve();
    }, 1000);
  });

  console.log('1');

  res.body = 'Hello World!';
});
app.use(async (req, res, next) => {
  await next();
  console.log('2');
});

app.use(async (req, res) => {
  await new Promise((resolve) => {
    setTimeout(() => {
      resolve();
    }, 1000);
  });

  console.log('1');

  res.body = 'Hello World!';
});

result:

$ node index.js
1
2
$ node index.js
1
2

Processor ​

processor is middleware that runs after all existing middleware has been executed.

ts
const { ZeptServer } = require('@zept/http');
const server = new ZeptServer();

server.useProcessor((req, res, next) => {
  console.log('processor called');
  next();
});
server.use((req, res, next) => {
  console.log('middleware called');
  next();
});

server.listen(3000);
const { ZeptServer } = require('@zept/http');
const server = new ZeptServer();

server.useProcessor((req, res, next) => {
  console.log('processor called');
  next();
});
server.use((req, res, next) => {
  console.log('middleware called');
  next();
});

server.listen(3000);
