Join Eve Porcello for an in-depth discussion in this video The component lifecycle, part of Learning React.js (2016).
- [Instructor] The component lifecycle provides hooks…for creation, lifetime, and teardown of components.…These methods allow you to do things like…add libraries, load data, and more at very specific times.…The mountain lifecycle has several methods…that we've used already.…For example, getInitialState is going to be called once…and will set the default for a state.…componentWillMount is called right before the render,…and it's the last chance to effect state…prior to the render.…The render method we know well, this is the only…required method, and componentDidMount is going to…fire right after the render, so after a successful render,…we can now access the dom, the component has been rendered,…and now the user can interact with it.…
The component lifecycle also provides methods for updating.…componentWillReceiveProps, once this method is called,…we get the opportunity to change the object…and effect state.…shouldComponentUpdate and componentWillUpdate…are invoked right before rendering,…and are often used for optimization.…
