Setup Undertaking
Let’s arrange a challenge to study the fundamentals of the categorical. Be sure to have put in the node in your system. You’ll be able to consult with this definitive information for the node set up course of.
- Create a challenge folder.
- Open it within the terminal.
- Set up the
categorical,body-parser,cookie-parser,cors, andnodemon. - Add the index.js file to the challenge.
- Add the appliance begin script within the
packages.jsonfile withnodemon index.jscommand.
Packages
- categorical: that is our software’s core bundle which helps us create APIs.
- body-parser: it is a middleware that parses the incoming information from the API and provides it to the
req.physique. - cookie-parser: it is a middleware that parses the header Cookie and provides it to the
req.cookie. - cors: it is a middleware that’s used to allow the CORS.
- nodemon: that is used to run our software which is able to restart the server each time any file modifications.
These are the fundamental packages required for the categorical software to make our lives simpler. Chances are you’ll want extra packages based mostly in your challenge. Don’t fear about it now, including packages is only a command away.
Specific App

const categorical = require("categorical");
const bodyParser = require("body-parser");
const cookieParser = require("cookie-parser");
const cors = require("cors");
// initializing the categorical
const app = categorical();
const port = 3000;
// including the middlewares to the app
app.use(bodyParser.json());
app.use(cookieParser());
app.use(cors());
// req: we'll use this paramter to get API request particulars
// res: we'll use
app.get("/", (req, res) => {
return res.ship("Hiya, World!");
});
app.get("/json", (req, res) => {
return res.json({ greetings: "Hiya, World!" }); // you can too use res.ship({})
});
app.get("/path-params/:title", (req, res) => {
// all the trail params will current in req.params object
const { title } = req.params;
return res.json({ greetings: `Hiya, ${title}!` });
});
app.get("/query-params", (req, res) => {
// all of the question params will current in req.question object
const { title } = req.question;
return res.json({ greetings: `Hiya, ${title ? title : "Geekflare"}!` });
});
app.put up("/put up", (req, res) => {
// information will current in req.physique
const { title } = req.physique;
console.log(req.physique);
return res.json({ greetings: `Hiya, ${title ? title : 'Geekflare'}!` });
});
app.pay attention(port, () => {
console.log(`App listening on port ${port}`);
});Begin the appliance with npm begin and check out all of the APIs that we have now written. Learn the documentation to study extra about every idea.
