First of all, I want to thank everyone who have made pull requests for Uptime Kuma. I never thought the GitHub community would be so nice! Because of this, I also never thought that other people would actually read and edit my code. It is not very well structured or commented, sorry about that.

Parts of the code are not very well-structured or commented, sorry about that.
The project was created with vite.js (vue3). Then I created a subdirectory called "server" for the server part. Both frontend and backend share the same `package.json`.
The project was created with `vite.js` and is written in `vue3`.
Our backend lives in the `server`-directory and mostly communicates via websockets.
Both frontend and backend share the same `package.json`.
The frontend code builds into "dist" directory. The server (express.js) exposes the "dist" directory as the root of the endpoint. This is how production is working.
## Key Technical Skills
- Node.js (You should know about promises, async/await, arrow functions, etc.)
- Socket.io
- SCSS
- Vue.js
- Bootstrap
- SQLite
For production, the frontend is build into `dist`-directory and the server (`express.js`) exposes the `dist` directory as the root of the endpoint.
For development, we run vite in development mode on another port.

I will assign your pull request to a [milestone](https://github.com/louislam/uptime-kuma/milestones), if I plan to review and merge it.
Also, please don't rush or ask for an ETA, because I have to understand the pull request, make sure it is no breaking changes and stick to my vision of this project, especially for large pull requests.

We have to understand the pull request, make sure it has no breaking changes and stick to the vision of this project, especially for large pull requests.
## I'd like to work on an issue. How do I do that?
We have found that assigning people to issues is management-overhead that we don't need.
A short comment that you want to try your hand at this issue is appreciated to save other devs time.
If you come across any problem during development, feel free to leave a comment with what you are stuck on.
### Recommended Pull Request Guideline
Before deep into coding, discussion first is preferred. Creating an empty pull request for discussion would be recommended.
Before diving deep into coding, having a discussion first by creating an empty pull request for discussion is preferred.
The rationale behind this is that we can align the direction and scope of the feature to eliminate any conflicts with existing and planned work, and can help by pointing out any potential pitfalls.
1. Fork the project
2. Clone your fork repo to local

## Project Styles
I personally do not like something that requires so many configurations before you can finally start the app. I hope Uptime Kuma installation will be as easy as like installing a mobile app.

- Easy to install for non-Docker users, no native build dependency is needed (for x86_64/armv7/arm64), no extra config, and no extra effort required to get it running
- Single container for Docker users, no very complex docker-compose file. Just map the volume and expose the port, then good to go

- mapping the volume and exposing the port should be the only requirements
- Settings should be configurable in the frontend. Environment variables are discouraged, unless it is related to startup such as `DATA_DIR`
- Easy to use
- The web UI styling should be consistent and nice

## Dependencies
Both frontend and backend share the same package.json. However, the frontend dependencies are eventually not used in the production environment, because it is usually also baked into dist files. So:
