# 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 (express.js) exposes the "dist" directory as root of the endpoint. 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 into 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.
|
|
|
|
- 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-compose file. Just map the volume and expose the port, then good to go
|
|
- Settings should be configurable in the frontend. Env var is not encouraged.
|
|
- Easy to use
|
|
|
|
# Coding Styles
|
|
|
|
- 4 spaces indentation
|
|
- Follow `.editorconfig`
|
|
- Follow ESLint
|
|
|
|
# Name convention
|
|
|
|
- Javascript/Typescript: camelCaseType
|
|
- SQLite: underscore_type
|
|
- CSS/SCSS: dash-type
|
|
|
|
# Tools
|
|
|
|
- Node.js >= 14
|
|
- Git
|
|
- IDE that supports ESLint and EditorConfig (I am using Intellji Idea)
|
|
- A SQLite tool (SQLite Expert Personal is suggested)
|

# How to start the Backend Dev Server
|
|
|
|
(2021-09-23 Update)
|
|
|
|
```bash
|
|
npm run start-server-dev
|
|
```
|
|
|
|
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.)
|
|
|
|
- model/ (Object model, auto mapping to the database table name)
|
|
- modules/ (Modified 3rd-party modules)
|
|
- notification-providers/ (indivdual notification logic)
|
|
- routers/ (Express Routers)
|
|
- scoket-handler (Socket.io Handlers)
|
|
- server.js (Server main logic)
|
|
|
|
# How to start the Frontend Dev Server
|
|
|
|
1. Set the env var `NODE_ENV` to "development".
|
|
2. Start the frontend dev server by the following command.
|
|
```bash
|
|
npm run dev
|
|
```
|
|
It binds to `0.0.0.0:3000` by default.
|
|
|
|
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
|
|
|
|
It is an end-to-end testing. It is using Jest and Puppeteer.
|
|
|
|
```
|
|
npm run build
|
|
npm test
|
|
```
|
|
|
|
By default, the Chromium window will be shown up during the test. Specifying `HEADLESS_TEST=1` for terminal environments.
|
|
|
|
# Update Dependencies
|
|
|
|
Install `ncu`
|
|
https://github.com/raineorshine/npm-check-updates
|
|
|
|
```bash
|
|
ncu -u -t patch
|
|
npm install
|
|
```
|
|
|
|
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
