express-use-request

#express-use-request

This is a small library for the nodejs express server, based on the async-hooks mechanism. It allows you to receive the current processed request from anywhere.

Installation

npm i express-use-request

API

middleware

First you need to connect middleware. It is recommended to connect it one of the first.

// index.js

let { middleware } = require('express-use-request');
let anyLib = require('./any-lib.js');

...

const app = express();

app.use(middleware);
app.get('/', (req, res) => {

    /**
     * There is no need passing req to anyMetod and to any nested deeper.
     */
    let result = anyLib.anyMetod({foo: 'bar'});
    
    res.status(200).send(result);
});

app.listen(3000);

useRequest

With the useRequest function, you can get the request to be processed anywhere. It may contain supporting information related to a specific request, which now does not need to be passed through the entire callstack.

// ./any-lib.js

const { useRequest } = require('express-use-request);

module.exports = {
    anyMethod: (params) => {
        // With the useRequest function, you can access a request from anywhere.
        let request = useRequest();
        
        ...
        
    }
};
