This is an npm package designed to mock curl requests in an Express.js application and write the corresponding response to a file.
This package can be useful for debugging or logging HTTP requests and responses in an Express.js application, and also helping you to mock received calls whenever you want.
You can install the package via npm:
npm install express-curl-mock-loggerconst fs = require("fs");
const express = require("express");
const bodyParser = require("body-parser");
const httpLoggerCreator = require("./index.js");
const app = express();
app.use(express.json());
app.use(express.urlencoded());
app.use(bodyParser.raw());
const skippUrlPattens = [/^\/a/, /^\/b/];
app.use(httpLoggerCreator(skippUrlPattens));
app.get("/", (req, res, next) => {
req.context = { a: 1, b: 2, c: 3 };
next();
});
app.get("/", (req, res) => {
res.status(200).json({ message: "Hello, world!" });
});
app.listen(3000, () => {
console.log("Server is running on port 3000");
});2. With the middleware in place, all incoming requests and corresponding responses will be logged to a file in the specified format.
The output logger file will be created in the following format:
Curl command: [Linux curl command]
[HTTP Response Headers]
[HTTP Response Body]The file will be located in the ./http-logs directory with a timestamp in the filename.
