# Project Info
|
|
|
|
First of all, thank you everyone who made pull requests for Uptime Kuma, I never thought GitHub Community can be that nice! And also because of this, I also never thought other people actually read my code and edit my code. It is not structed and commented so well, lol. Sorry about that.
|
|
|
|
The project was created with vite.js (vue3). Then I created a sub-directory called "server" for server part. Both frontend and backend share the same package.json.
|
|
|
|
The frontend code build into "dist" directory. The server uses "dist" as root. This is how production is working.
|
|
|
|
# Can I create a pull request for Uptime Kuma?
|
|
|
|
Generally, if the pull request is working fine and it do not affect any existing logic, workflow and perfomance, I will merge to the master branch once it is tested.
|
|
|
|
If you are not sure, feel free to create an empty pull request draft first.
|
|
|
|

# Project Styles
|
|
|
|
I personally do not like something need to learn so much and need to config so much before you can finally start the app.
|
|
|
|
For example, recently, because I am not a python expert, I spent a 2 hours to resolve all problems in order to install and use the Apprise cli. Apprise requires so many hidden requirements, I have to figure out myself how to solve the problems by Google search for my OS. That is painful. I do not want Uptime Kuma to be like this way, so:
|
|
|
|
- Easy to install for non-Docker users, no native build dependency is needed (at least for x86_64), no extra config, no extra effort to get it run
|
|
- Single container for Docker users, no very complex docker-composer file. Just map the volume and expose the port, then good to go
|
|
- All settings in frontend.
|
|
- Easy to use
|
|
|
|
# Coding Styles
|
|
|
|
- Follow `.editorconfig`
|
|
- Follow ESLint
|
|
|
|
## Name convention
|
|
|
|
- Javascript/Typescript: camelCaseType
|
|
- SQLite: underscore_type
|
|
- CSS/SCSS: dash-type
|
|
|
|
# Tools
|
|
|
|
- Node.js >= 14
|
|
- Git
|
|
- IDE that supports EditorConfig and ESLint (I am using Intellji Idea)
|
|
- A SQLite tool (I am using SQLite Expert Personal)
|
|
|
|
# Install dependencies
|
|
|
|
```bash
|
|
npm install --dev
|
|
```
|
|
|
|
For npm@7, you need --legacy-peer-deps
|
|
|
|
```bash
|
|
npm install --legacy-peer-deps --dev
|
|
```
|
|
|
|
# Backend Dev
|
|
|
|
```bash
|
|
npm run start-server
|
|
|
|
# Or
|
|
|
|
node server/server.js
|
|
```
|
|
|
|
It binds to `0.0.0.0:3001` by default.
|
|
|
|
## Backend Details
|
|
|
|
It is mainly a socket.io app + express.js.
|
|
|
|
express.js is just used for serving the frontend built files (index.html, .js and .css etc.)
|
|
|
|
# Frontend Dev
|
|
|
|
Start frontend dev server. Hot-reload enabled in this way. It binds to `0.0.0.0:3000` by default.
|
|
|
|
```bash
|
|
npm run dev
|
|
```
|
|
|
|
PS: You can ignore those scss warnings, those warnings are from Bootstrap that I cannot fix.
|
|
|
|
You can use Vue.js devtools Chrome extension for debugging.
|
|
|
|
After the frontend server started. It cannot connect to the websocket server even you have started the server. You need to tell the frontend that is a dev env by running this in DevTool console and refresh:
|
|
|
|
```javascript
|
|
localStorage.dev = "dev";
|
|
```
|
|
|
|
So that the frontend will try to connect websocket server in 3001.
|
|
|
|
Alternately, you can specific `NODE_ENV` to "development".
|
|
|
|
## 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{num}.sql` in `./db/`
|
|
2. Update `latestVersion` in `./server/database.js`
|
|
|
|
# Unit Test
|
|
|
|
Yes, no unit test for now. I know it is very important, but at the same time my spare time is very limited. I want to implement my ideas first. I will go back to this in some points.
