const express = require('express');
const app = express();
app.use('/', anyroute);
// in anyroute file
router.route('/:id').get(controlFunction)
controlFunction(req, res, res)=> {
// Here we can get the "id" from the variable with req.param.id
}
however, my goal is to utilize the 'id' before entering this controller function. This can be achieved like so
modifyFunction(userId)=> {
// Perform actions using the userId
}
router.route('/:id').get(modifyFunction(id), controlFunction)
Can I retrieve the 'id' from the URL using Express and Javascript and use it in modifyFunction(id) prior to handling the request?
In an Express middleware, the req and res variables are passed from one middleware to another. Nevertheless, I have created a function named function(type, id) which produces a middleware function (req, res, next). In this function(type, id), the type parameter is manually provided while the id is extracted from the URL.
router
.route('/all-contacts/:id')
.get(authController.isLoggedIn, viewController.getAxiosConfig('contactNameEmail', id), viewController.getAllContact);
exports.getAxiosConfig = (type, id) => {
return (req, res, next) => {
const config = axiosConfig(type, id);
const accessToken = req.cookies.access_token;
const tokenArray = config.headers.Authorization.split(' ');
tokenArray.splice(1, 1, accessToken);
const newToken = tokenArray.join(' ');
config.headers.Authorization = newToken;
req.config = config;
next();
};
};
exports.getAllContact = catchAsync(async (req, res, next) => {
// const token = req.cookies.access_token;
// console.log(token);
// const config = axiosConfig('contactNameEmail');
req.config.method = 'GET';
// const tokenArray = config.headers.Authorization.split(' ');
// tokenArray.splice(1, 1, token);
// const newToken = tokenArray.join(' ');
// config.headers.Authorization = newToken;
const contacts = await axios(req.config);
console.log(req.config);
const { data } = contacts;
res.status(200).render('contactList', {
title: 'All contacts',
data
});
});
