Create a database.json with an initial structure: { "posts": [] } Use code with caution. Copied to clipboard
fetch('http://localhost:3000/posts', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ title: "My First Post", content: "This is some data saved to database.json!" }), }) .then(response => response.json()) .then(data => console.log('Success:', data)); Use code with caution. Copied to clipboard 2. Using Node.js (Direct File Writing) database.json
: JSON requires double quotes for keys and string values; single quotes will cause an error. Create a database
const fs = require('fs'); const newPost = { id: Date.now(), title: "Direct Write", content: "Added via fs module" }; // 1. Read the existing file const data = fs.readFileSync('database.json'); const db = JSON.parse(data); // 2. Add the new post db.posts.push(newPost); // 3. Write it back fs.writeFileSync('database.json', JSON.stringify(db, null, 2)); Use code with caution. Copied to clipboard 3. Using Python Python is often used for simple JSON "databases": Using Node
You can now send a POST request to http://localhost:3000/posts using fetch in JavaScript: javascript
