# Project Info
|
|
|
|
First of all, I want to thank everyone who 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.
|
|
|
|
The project was created with vite.js (vue3). Then I created a subdirectory called "server" for server part. Both frontend and backend share the same package.json.
|
|
|
|
The frontend code build into "dist" directory. The server (express.js) exposes the "dist" directory as root of the endpoint. This is how production is working.
|
|
|
|
## Key Technical Skills
|
|
|
|
- Node.js (You should know what are promise, async/await and arrow function etc.)
|
|
- Socket.io
|
|
- SCSS
|
|
- Vue.js
|
|
- Bootstrap
|
|
- SQLite
|
|
|
|
## Directories
|
|
|
|
- config (dev config files)
|
|
- data (App data)
|
|
- db (Base database and migration scripts)
|
|
- dist (Frontend build)
|
|
- docker (Dockerfiles)
|
|
- extra (Extra useful scripts)
|
|
- public (Frontend resources for dev only)
|
|
- server (Server source code)
|
|
- src (Frontend source code)
|
|
- test (unit test)
|
|
|
|
## Can I create a pull request for Uptime Kuma?
|
|
|
|
Yes or no, it depends on what you will try to do. Since I don't want to waste your time, be sure to **create an empty draft pull request or open an issue, so we can have a discussion first**. Especially for a large pull request or you don't know it will be merged or not.
|
|
|
|
Here are some references:
|
|
|
|
✅ Usually Accept:
|
|
- Bug fix
|
|
- Security fix
|
|
- Adding notification providers
|
|
- Adding new language files (You should go to https://weblate.kuma.pet for existing languages)
|
|
- Adding new language keys: `$t("...")`
|
|
|
|
⚠️ Discussion First
|
|
- Large pull requests
|
|
- New features
|
|
|
|
❌ Won't Merge
|
|
- A dedicated pr for translating existing languages (You can now translate on https://weblate.kuma.pet)
|
|
- Do not pass auto test
|
|
- Any breaking changes
|
|
- Duplicated pull request
|
|
- Buggy
|
|
- UI/UX is not close to Uptime Kuma
|
|
- Existing logic is completely modified or deleted for no reason
|
|
- A function that is completely out of scope
|
|
- Convert existing code into other programming languages
|
|
- Unnecessary large code changes (Hard to review, causes code conflicts to other pull requests)
|
|
|
|
The above cases cannot cover all situations.
|
|
|
|
I (@louislam) have the final say. If your pull request does not meet my expectations, I will reject it, no matter how much time you spend on it. Therefore, it is essential to have a discussion beforehand.
|
|
|
|
I will mark your pull request in the [milestones](https://github.com/louislam/uptime-kuma/milestones), if I am plan to review and merge it.
|
|
|
|
Also, please don't rush or ask for 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.
|
|
|
|
|
|
### Recommended Pull Request Guideline
|
|
|
|
Before deep into coding, discussion first is preferred. Creating an empty pull request for discussion would be recommended.
|
|
|
|
1. Fork the project
|
|
1. Clone your fork repo to local
|
|
1. Create a new branch
|
|
1. Create an empty commit
|
|
`git commit -m "[empty commit] pull request for <YOUR TASK NAME>" --allow-empty`
|
|
1. Push to your fork repo
|
|
1. Create a pull request: https://github.com/louislam/uptime-kuma/compare
|
|
1. Write a proper description
|
|
1. Click "Change to draft"
|
|
1. Discussion
|
|
|
|
## 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 could 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, 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
|
|
- Settings should be configurable in the frontend. Environment variable is not encouraged, unless it is related to startup such as `DATA_DIR`
|
|
- Easy to use
|
|
- The web UI styling should be consistent and nice
|
|
|
|
## Coding Styles
|
|
|
|
- 4 spaces indentation
|
|
- Follow `.editorconfig`
|
|
- Follow ESLint
|
|
- Methods and functions should be documented with JSDoc
|
|
|
|
## Name Conventions
|
|
|
|
- Javascript/Typescript: camelCaseType
|
|
- SQLite: snake_case (Underscore)
|
|
- CSS/SCSS: kebab-case (Dash)
|
|
|
|
## Tools
|
|
|
|
- Node.js >= 14
|
|
- NPM >= 8.5
|
|
- Git
|
|
- IDE that supports ESLint and EditorConfig (I am using IntelliJ IDEA)
|
|
- A SQLite GUI tool (SQLite Expert Personal is suggested)
|
|
|
|
## Install Dependencies for Development
|
|
|
|
```bash
|
|
npm ci
|
|
```
|
|
|
|
## Dev Server
|
|
|
|
(2022-04-26 Update)
|
|
|
|
We can start the frontend dev server and the backend dev server in one command.
|
|
|
|
Port `3000` and port `3001` will be used.
|
|
|
|
```bash
|
|
npm run dev
|
|
```
|
|
|
|
But sometimes, you would like to keep restart the server, but not the frontend, you can run these command in two terminals:
|
|
```
|
|
npm run start-frontend-dev
|
|
npm run start-server-dev
|
|
```
|
|
|
|
## Backend Server
|
|
|
|
It binds to `0.0.0.0:3001` by default.
|
|
|
|
|
|
It is mainly a socket.io app + express.js.
|
|
|
|
express.js is used for:
|
|
- entry point such as redirecting to a status page or the dashboard
|
|
- serving the frontend built files (index.html, .js and .css etc.)
|
|
- serving internal APIs of status page
|
|
|
|
|
|
### Structure in /server/
|
|
|
|
- jobs/ (Jobs that are running in another process)
|
|
- model/ (Object model, auto mapping to the database table name)
|
|
- modules/ (Modified 3rd-party modules)
|
|
- monitor_types (Monitor Types)
|
|
- notification-providers/ (individual notification logic)
|
|
- routers/ (Express Routers)
|
|
- socket-handler (Socket.io Handlers)
|
|
- server.js (Server entry point)
|
|
- uptime-kuma-server.js (UptimeKumaServer class, main logic should be here, but some still in `server.js`)
|
|
|
|
## Frontend Dev Server
|
|
|
|
It binds to `0.0.0.0:3000` by default. Frontend dev server is used for development only.
|
|
|
|
For production, it is not used. It will be compiled to `dist` directory instead.
|
|
|
|
You can use Vue.js devtools Chrome extension for debugging.
|
|
|
|
### Build the frontend
|
|
|
|
```bash
|
|
npm run build
|
|
```
|
|
|
|
### Frontend Details
|
|
|
|
Uptime Kuma Frontend is a single page application (SPA). Most paths are handled by Vue Router.
|
|
|
|
The router is in `src/router.js`
|
|
|
|
As you can see, most data in frontend is stored in root level, even though you changed the current router to any other pages.
|
|
|
|
The data and socket logic are in `src/mixins/socket.js`.
|
|
|
|
## Database Migration
|
|
|
|
1. Create `patch-{name}.sql` in `./db/`
|
|
2. Add your patch filename in the `patchList` list in `./server/database.js`
|
|
|
|
## Unit Test
|
|
|
|
```bash
|
|
npm run build
|
|
npm test
|
|
```
|
|
|
|
## 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:
|
|
|
|
- Frontend dependencies = "devDependencies"
|
|
- Examples: vue, chart.js
|
|
- Backend dependencies = "dependencies"
|
|
- Examples: socket.io, sqlite3
|
|
- Development dependencies = "devDependencies"
|
|
- Examples: eslint, sass
|
|
|
|
### Update Dependencies
|
|
|
|
Since previously updating Vite 2.5.10 to 2.6.0 broke the application completely, from now on, it should update patch release version only.
|
|
|
|
Patch release = the third digit ([Semantic Versioning](https://semver.org/))
|
|
|
|
If for maybe security reasons, a library must be updated. Then you must need to check if there are any breaking changes.
