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 structured and commented so well, lol. 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
- data (App data)
- dist (Frontend build)
- 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?
⚠️ 2022-03-02 Update:
Since I found that merging pull requests is a pretty heavy task for me, I try to rearrange it.
✅ Accept:
- Bug/Security fix
- Translations
- Adding notification providers
❌ Avoid:
- Large pull requests
- New big features
My long story here: https://www.reddit.com/r/UptimeKuma/comments/t1t6or/comment/hynyijx/
Recommended Pull Request Guideline
Before deep into coding, disscussion first is preferred. Creating an empty pull request for disscussion would be recommended.
- Fork the project
- Clone your fork repo to local
- Create a new branch
- Create an empty commit
git commit -m "[empty commit] pull request for <YOUR TASK NAME>" --allow-empty
- Push to your fork repo
- Create a pull request: https://github.com/louislam/uptime-kuma/compare
- Write a proper description
- Click "Change to draft"
- Discussion
❌ Won't Merge
- Any breaking changes
- Duplicated pull request
- Buggy
- Existing logic is completely modified or deleted
- A function that is completely out of scope
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
- Methods and funtions should be documented with JSDoc
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 IntelliJ IDEA)
- A SQLite tool (SQLite Expert Personal is suggested)

How to start the Backend Dev Server
(2021-09-23 Update)
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/ (individual notification logic)
- routers/ (Express Routers)
- socket-handler (Socket.io Handlers)
- server.js (Server main logic)
How to start the Frontend Dev Server
-
Set the env var
NODE_ENV
to "development". -
Start the frontend dev server by the following command.
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
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
- Create
patch-{name}.sql
in./db/
- 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
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 (Semantic Versioning)
