# Project Info
2021-11-17 00:09:12 -06:00
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.
2021-07-31 11:29:30 -05:00
2021-12-02 04:15:14 -06:00
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.
2021-07-31 11:29:30 -05:00
2021-10-03 03:04:16 -05:00
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?
2021-08-24 01:42:35 -05:00
2022-06-01 01:08:10 -05:00
Yes, you can. However, since I don't want to waste your time, be sure to **create empty draft pull request, so we can discuss first** if it is a large pull request or you don't know it will be merged or not.
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.
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.

## Project Styles

2021-09-12 12:23:51 -05:00
I personally do not like something need to learn so much and need to config so much before you can finally start the app.
2021-07-31 11:29:30 -05:00
- 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
2021-10-10 01:40:19 -05:00
- Single container for Docker users, no very complex docker-compose file. Just map the volume and expose the port, then good to go
2022-06-01 01:08:10 -05:00
- Settings should be configurable in the frontend. Environment variable is not encouraged, unless it is related to startup such as `DATA_DIR` .
2021-07-31 11:29:30 -05:00
- Easy to use
2022-06-01 01:08:10 -05:00
- The web UI styling should be consistent and nice.

2021-10-12 19:01:34 -05:00
## Install dependencies
2021-07-31 11:29:30 -05:00
```bash
2021-10-03 03:04:16 -05:00
npm ci
2021-08-31 07:36:17 -05:00
```
2022-04-25 13:20:13 -05:00
## Dev Server
2021-07-31 11:29:30 -05:00
2022-04-25 13:20:13 -05:00
(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.
2021-07-31 11:29:30 -05:00
2021-09-23 09:48:19 -05:00
```bash
2022-04-25 13:20:13 -05:00
npm run dev
2021-07-31 11:29:30 -05:00
```
2022-04-25 13:20:13 -05:00
## Backend Server
2021-07-31 11:29:30 -05:00
2022-04-28 22:35:03 -05:00
It binds to `0.0.0.0:3001` by default.
2021-07-31 11:29:30 -05:00
It is mainly a socket.io app + express.js.
2022-04-25 13:27:37 -05:00
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
2021-07-31 11:29:30 -05:00
2022-04-25 13:20:13 -05:00
### Structure in /server/
2021-10-03 03:04:16 -05:00
- model/ (Object model, auto mapping to the database table name)
- modules/ (Modified 3rd-party modules)
2021-11-17 00:09:12 -06:00
- notification-providers/ (individual notification logic)
2021-10-03 03:04:16 -05:00
- routers/ (Express Routers)
2021-12-02 04:15:14 -06:00
- socket-handler (Socket.io Handlers)
2022-04-25 13:20:13 -05:00
- server.js (Server entry point and main logic)
2021-07-31 11:29:30 -05:00
2022-04-25 13:20:13 -05:00
## Frontend Dev Server
2021-10-12 19:01:34 -05:00
2022-04-25 13:20:13 -05:00
It binds to `0.0.0.0:3000` by default. Frontend dev server is used for development only.
2021-10-12 19:01:34 -05:00
2022-04-25 13:20:13 -05:00
For production, it is not used. It will be compiled to `dist` directory instead.
2021-07-31 11:29:30 -05:00
2021-09-12 12:23:51 -05:00
You can use Vue.js devtools Chrome extension for debugging.
2021-07-31 11:29:30 -05:00
2021-10-12 19:01:34 -05:00
### Build the frontend
2021-07-31 11:29:30 -05:00
```bash
npm run build
```
2021-10-12 19:01:34 -05:00
### Frontend Details
2021-07-31 11:29:30 -05:00
Uptime Kuma Frontend is a single page application (SPA). Most paths are handled by Vue Router.
2021-09-12 12:23:51 -05:00
The router is in `src/router.js`
2021-07-31 11:29:30 -05:00
As you can see, most data in frontend is stored in root level, even though you changed the current router to any other pages.
2021-09-12 12:23:51 -05:00
The data and socket logic are in `src/mixins/socket.js` .
2021-07-31 11:29:30 -05:00
2021-10-12 19:01:34 -05:00
## Database Migration
2021-07-31 11:29:30 -05:00
2021-10-03 03:04:16 -05:00
1. Create `patch-{name}.sql` in `./db/`
2. Add your patch filename in the `patchList` list in `./server/database.js`
2021-07-31 11:29:30 -05:00
2021-10-12 19:01:34 -05:00
## Unit Test
2021-07-31 11:29:30 -05:00
2021-10-05 07:27:43 -05:00
It is an end-to-end testing. It is using Jest and Puppeteer.
2021-10-05 05:17:54 -05:00
2021-10-12 19:01:34 -05:00
```bash
2021-10-05 07:27:43 -05:00
npm run build
npm test
```
By default, the Chromium window will be shown up during the test. Specifying `HEADLESS_TEST=1` for terminal environments.
2021-10-05 05:17:54 -05:00
2022-09-19 06:39:30 -05:00
## Dependencies
Both frontend and backend share the same package.json. However, the frontend dependencies are eventually not be used in 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
2021-10-05 05:17:54 -05:00
Install `ncu`
https://github.com/raineorshine/npm-check-updates
```bash
ncu -u -t patch
npm install
```
2021-12-02 04:15:14 -06:00
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.
2021-10-05 05:17:54 -05:00
2021-10-12 19:01:34 -05:00
Patch release = the third digit ([Semantic Versioning](https://semver.org/))
