Supercharge Your Vanilla JavaScript Framework: Advanced Features and Techniques
In our last adventure, we built a simple, yet functional JavaScript framework from scratch. If you missed it, I highly recommend checking it out to get a solid foundation before diving into this follow-up. Now, it’s time to level up and add some advanced features that will make our framework even more powerful and user-friendly. Buckle up, because we’re about to dive into some exciting enhancements!
In our previous article, we covered the basics: creating a component system, setting up routing, and managing state. Now, we’ll explore more advanced concepts such as lifecycle methods, reactive data binding, custom events, and more.
Component Lifecycle Methods
Lifecycle methods allow you to hook into different stages of a component’s existence. We’ll add componentDidMount
, componentDidUpdate
, and componentWillUnmount
to our base Component
class.

class Component {
constructor(props = {}) {
this.props = props;
this.state = {};
this.lifecycleMethods = {
componentDidMount: () => {},
componentDidUpdate: () => {},
componentWillUnmount: () => {}
};
}
setState(newState) {
this.state = { ...this.state, ...newState }…
