Introduction.

Hello and welcome back. I hope you are well. Still on the project walkthrough, if you missed the first article on this series, you can find it here.

In this article, I will be discussing how unauthenticated users can access articles. I will implement the routes which I like to call "public routes". Let's get started.

Get published article.

/controllers/publicController.js

const articleModel = require("../models/articleModel");
const userModel = require("../models/userModel");
const getPublishedArticle = async (req, res, next) => {
  try {
    const id = req.params.id;
    const article = await articleModel
      .findById(id)
      .populate("author", "first_name last_name");
    if (article.state === "published") {
      article.read_count++;
      await article.save();
      res.status(200).send(article);
    } else {
      res.send("You can only view published article");
    }
  } catch (err) {
    next(err);
  }
};
module.exports = { getPublishedArticle };

The code above starts by importing the article and user models. The getPublishedArticle() function finds an article with a particular id. If the article exists, it is returned and the read count is increased.

/routes/publicRoutes.js

const express = require('express')
const publicRouter = express.Router()
const publicController= require('../controllers/publicController')
publicRouter.get('/article/publish/:id', publicController.getPublishedArticle)
module.exports = publicRouter

Route ==> /api/article/publish/:id

/app.js

const publicRouter = require('./routes/publicRoute')
app.use('/api', publicRouter)

Conclusion.

In this article, we discussed how unauthenticated users can access some routes in the application.
