Creating a Simple Blogging Platform with TypeScript


In this guide, we will create a basic blogging platform using TypeScript. While this example is simplified and lacks the advanced features of a real-world platform, it provides a starting point for understanding how to structure and build a web application.


Our simple blogging platform will include the following features:

  • Post Creation: Users can create new blog posts with titles and content.
  • Post Listing: A list of all blog posts is displayed on the main page.
  • Post Viewing: Users can click on a post to view its details.

Setting Up the Project

To create our blogging platform, follow these steps:

1. Create a Project Folder

Create a folder for your project and open it in your code editor. You can name the folder as per your preference.

2. Initialize a Node.js Project

Open your terminal or command prompt, navigate to your project folder, and run the following command to create a package.json file for your project:

npm init -y

3. Install TypeScript and Express

Install TypeScript and Express, which will be the foundation of our blogging platform:

npm install typescript express --save-dev

4. Configure TypeScript

Create a tsconfig.json file in your project folder and configure it for TypeScript:

"compilerOptions": {
"target": "ES6",
"module": "CommonJS",
"outDir": "./dist"
"include": [

Creating the Blogging Platform

We'll structure our blogging platform with three main components: routes, controllers, and views. Here's a simplified code example:

1. Create TypeScript Files

Create the following TypeScript files in your project's src folder:


import express from 'express';
import { blogRouter } from './routes/blog';
const app = express();
const port = 3000;
app.use('/blog', blogRouter);
app.get('/', (req, res) => {
res.send('Welcome to our Blogging Platform');
app.listen(port, () => {
console.log(`Server is running on port ${port}`);


import express from 'express';
import { getAllPosts, getPost } from '../controllers/blog';
export const blogRouter = express.Router();
blogRouter.get('/', getAllPosts);
blogRouter.get('/:id', getPost);


import { Request, Response } from 'express';
const posts = [
{ id: 1, title: 'First Post', content: 'This is the content of the first post.' },
{ id: 2, title: 'Second Post', content: 'This is the content of the second post.' },
export const getAllPosts = (req: Request, res: Response) => {
export const getPost = (req: Request, res: Response) => {
const postId = parseInt(, 10);
const post = posts.find((p) => === postId);
if (!post) {
res.status(404).json({ error: 'Post not found' });
} else {

2. Run the Application

Open your terminal and run the TypeScript compiler to transpile your TypeScript code:


Run the application:

node ./dist/app.js

Your blogging platform is now running. You can access it by visiting http://localhost:3000 in your web browser.


Creating a fully-featured blogging platform is a significant undertaking, but this simplified example provides a foundation for building more complex web applications. As you explore TypeScript and Express, you can expand and enhance your blogging platform with additional features, database integration, user authentication, and more.
