Why EJS template setup in Express? - Purpose & Use Cases
The Scenario
Imagine building a website where you have to write the same HTML structure over and over for every page, manually inserting data each time.
The Problem
Manually copying and pasting HTML with data inserted by hand is slow, repetitive, and easy to make mistakes. Updating the layout means changing every page separately.
The Solution
EJS templates let you write HTML with placeholders for data. You write the layout once, and EJS fills in the data automatically when the page loads.
Before vs After
✗ Before
res.send("<html><body><h1>Welcome, " + userName + "</h1></body></html>");
✓ After
res.render('index', { userName: userName });What It Enables
You can create dynamic web pages easily, reusing templates and separating design from data.
Real Life Example
A blog site where each post page uses the same template but shows different post content automatically.
Key Takeaways
Manual HTML duplication is slow and error-prone.
EJS templates separate HTML layout from data.
This makes dynamic page creation simple and maintainable.
