explore express middlewares and use an auth middleware instead of checking of the cookie for each route.

Added the auth middleware wherever necessary

res.status(200).send(repo_data);
} else {
res.status(401).send("Unauthorized Access. Please Login");
}
});

app.get('/getrepodetail', (req, res) => {
if (req.cookies.auth === 'loggedin') {
let name = req.query.name;
if (name) {
if (specialwords(name)) {
res.status(400).send("Please avoid using special characters");
} else {

Lets move this to middleware as well. In this middleware you can do req.name = req.query.name and next middleware will have access to req.name. Similarly create sanitization middleware for all the routes.

let specificRepo = repo_data.find(repo => repo.repo_name === name);
if (specificRepo === undefined) {
res.status(404).send("No repo matching the provided name exists");
} else {
res.status(200).send(specificRepo);
}
}
} else {
res.status(400).send("Please provide a repo name");
}
} else {
res.status(401).send("Unauthorized Access. Please Login");
}
});

app.post('/create-repo', (req, res) => {
if (req.cookies.auth === 'loggedin') {
const data = req.body;

if (specialwords(data.repo_name) || specialwords(data.repo_author) || specialwords(data.details)) {
res.status(400).send("Please avoid special characters in Name, Author, and Details");
} else if (typeof data.year_created !== "number" || typeof data.commits !== "number") {
res.status(400).send("Please use numbers when providing commits and year created");

Made the changes by including a repovalidation middleware function and chained it to the create-repo route

} else {
repo_data.push(data);
res.status(201).send("Repo Created");
}
} else {
res.status(401).send("Unauthorized Access. Please Login");
}
});
