## Working application
Check out the **working app** -> https://sepg.netlify.app/
![SuperExpressive Playground by @nartc][demo]
## Features
- Use the code editor to write **Regular Expression** using **SuperExpressive API**
- Test the generated RegExp
- [x] Mobile friendly - [@trungk18][trung]
- [ ] Automatic execution
## Technologies
- [Angular](https://angular.io)
- [Scully](https://scully.io)
- [Monaco Editor](https://microsoft.github.io/monaco-editor/)
- [NgxMonacoEditor](https://github.com/atularen/ngx-monaco-editor)
- [TailwindCSS](https://tailwindcss.com/)
## Challenges
There are a couple of challenges that I ran into while working on this project.
### Monaco Editor
Monaco is a powerful library, but it's also very complex. The way it's loaded is pretty tricky. However, the integration is quite smooth using `ngx-monaco-editor`. It was quite satisfied when I was able to load extra library type definitions (for SuperExpressive intellisense) into the Monaco instance
### Executing the value of the editor
This is one tricky task as `eval()` is considered bad practice. So, I use `new Function()` instead. Also, I need to execute a snippet like:
```ts
SuperExpressive().anyChar.toRegex();
```
which will execute `SuperExpressive()` which is a 3rd-party API. Hence, in order for me to execute that, I need to assign `SuperExpressive` onto the `window` object.
```ts
import SuperExpressive from "super-expressive";
window.SuperExpressive = SuperExpressive;
```
Furthermore, I only want to execute a single-invoke of `SuperExpressive()` at a time, so I need to trim the editor's value.
### Scully and Monaco
Scully **will not** work with Monaco as is because Scully will generate the `html` from the Angular build bundle and in turns will inject several `` tags that were used to load Monaco. With multiple `<script>` tags with the same value (because Scully generates multiple `html` for multiple routes), Monaco complains that it's already been loaded.
To resolve that, I write a quick plugin to remove Monaco related `<script>` from the generated `html` by Scully.
```ts
function removeMonacoScriptPluginHandler(html: string) {
return Promise.resolve(
html
.replace(/<script.+(?:editor\.main(?:\.nls)\.js)"><\/script>/g, "") // remove duplicate loader
.replace(/<script.+(?:tsMode\.js|typescript\.js)"><\/script>/g, "") // remove duplicate loader
.replace(/<ngx-monaco-editor.+><\/ngx-monaco-editor>/g, "") // remove flickering
);
}
```
### Mobile Responsiveness
Again, because of how Monaco is loaded and rendered, it's tricky to get Mobile Responsiveness right which I haven't paid too much attention to for the first iteration.
