Serve the object {"message": "Hello json"} as a response, in JSON format, to GET requests to the /json route. Then point your browser to your-app-url/json, you should see the message on the screen.
Solution
This task seems to be related to web development, specifically using a framework like Express.js in Node.js. Here's a step-by-step guide on how to achieve this:
-
First, you need to set up your server. If you haven't already, you can install Express.js by running
npm install expressin your terminal. -
Once you have Express.js installed, you can create a new file (let's call it
app.js) and set up a basic server:
const express = require('express');
const app = express();
const port = 3000;
app.listen(port, () => {
console.log(`Server running at http://localhost:${port}`);
});
- Now, you can add a route that responds to GET requests at the
/jsonendpoint. You can use theres.json()function to send a JSON response:
app.get('/json', (req, res) => {
res.json({"message": "Hello json"});
});
Your complete app.js file should now look like this:
const express = require('express');
const app = express();
const port = 3000;
app.get('/json', (req, res) => {
res.json({"message": "Hello json"});
});
app.listen(port, () => {
console.log(`Server running at http://localhost:${port}`);
});
-
You can now start your server by running
node app.jsin your terminal. -
Finally, you can test your endpoint by navigating to
http://localhost:3000/jsonin your web browser. You should see{"message":"Hello json"}displayed on the page.

Create a .env file in the root of your project directory, and store the variable MESSAGE_STYLE=uppercase in it.Then, in the /json GET route handler you created in the last challenge access process.env.MESSAGE_STYLE and transform the response object's message to uppercase if the variable equals uppercase. The response object should either be {"message": "Hello json"} or {"message": "HELLO JSON"}, depending on the MESSAGE_STYLE value. Note that you must read the value of process.env.MESSAGE_STYLE inside the route handler, not outside of it, due to the way our tests run.If you are working locally, you will need the dotenv package. It loads environment variables from your .env file into process.env. The dotenv package has already been installed, and is in your project's package.json file. At the top of your myApp.js file, add require('dotenv').config() to load the environment variables.

Build an API endpoint, mounted at GET /name. Respond with a JSON document, taking the structure { name: 'firstname lastname'}. The first and last name parameters should be encoded in a query string e.g. ?first=firstname&last=lastname.Note: In the following exercise you are going to receive data from a POST request, at the same /name route path. If you want, you can use the method app.route(path).get(handler).post(handler). This syntax allows you to chain different verb handlers on the same path route. You can save a bit of typing, and have cleaner code.
