This Gist works for CRA 3. For CRA 4, you can try community maintained craco plugin for converting to a single-spa application at https://github.com/hasanayan/craco-plugin-single-spa-application (thanks @hasanayan):

1. Install react-app-rewired, as explained in https://github.com/timarney/react-app-rewired.
2. Create a file in src called single-spa-entry.js (or tsx for typescript)
3. Modify config-overrides.js, as shown in the config-overrides.js file provided in this gist.
4. (Optional) remove src/main.js, since single-spa-entry is the new entry
5. (Optional) remove public/index.html, since single-spa applications share a single html file, instead of one html file per project.

Frontend Technical Interview Prep

EDIT: Well this has been linked now so just an FYI this is still TBD. Feel free to comment if you have suggestions for improvements. Also here is an unrolled Twitter thread of a lot of the tips I talk about on here.

I've been doing frontend for a while now and one thing that really gripes me is the interview. I think the breadth of knowledge of a "Frontend Engineer" has been so poorly defined that people really just expected you to know everything. Many companies have made this a hybrid role. The Web is massive and there are many MANY things to know. Some of these things are just facts that you learn and others are things you really have to understand.

Every time I interview, I go over the same stuff. I wanted to create a gist of the TL;DR things that would jog my memory and hopefully yours too.

Lots of these things are real things I've been asked that caught me off guard. It's nice to have something you ca

Vue.js 2 Lifecycle hooks

beforeCreate() : This method is called synchronously after the Vue instance has just been initialized, before data observation and event/watcher setup.

created() : This method is called synchronously after the Vue instance is created. Data observation, computed properties, methods and event callbacks have already been set up at this stage but the mounting phase has not started yet.

beforeMount() : This method is called right before the component is mounted. So it is called before the render method is executed.

mounted() : This method is called after the component has just been mounted.

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
