First of all, I want to thank everyone who have 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.
First of all, I want to thank everyone who have wrote issues or shared 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.
Parts of the code are 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 the server part. Both frontend and backend share the same `package.json`.
The project was created with `vite.js` and is written in `vue3`.
Our backend lives in the `server`-directory and mostly communicates via websockets.
Both frontend and backend share the same `package.json`.
The frontend code builds into "dist" directory. The server (express.js) exposes the "dist" directory as the root of the endpoint. This is how production is working.
## Key Technical Skills
- Node.js (You should know about promises, async/await, arrow functions, etc.)
- Socket.io
- SCSS
- Vue.js
- Bootstrap
- SQLite
For production, the frontend is build into `dist`-directory and the server (`express.js`) exposes the `dist` directory as the root of the endpoint.
For development, we run vite in development mode on another port.

## 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 if it will be merged or not.
Here are some references:
### ✅ Usually accepted
- Bug fix
- Security fix
- Adding notification providers
- Adding new language files (see [these instructions](https://github.com/louislam/uptime-kuma/blob/master/src/lang/README.md))
- Adding new language keys: `$t("...")`
### ⚠️ Discussion required
- Large pull requests
- New features
### ❌ Won't be merged
Yes or no, it depends on what you will try to do.
Both your and our maintainers time is precious, and we don't want to waste both time.
If you have any questions about any process/.. is not clear, you are likely not alone => please ask them ^^
Different guidelines exist for different types of pull requests (PRs):
Submitting security fixes is something that may put the community at risk.
Please read through our [security policy](SECURITY.md) and submit vulnerabilities via an [advisory](https://github.com/louislam/uptime-kuma/security/advisories/new) + [issue](https://github.com/louislam/uptime-kuma/issues/new?assignees=&labels=help&template=security.md) instead.
We encourage you to submit how to fix a vulnerability if you know how to, this is not required.
Following the security policy allows us to properly test, fix bugs.
This review allows us to notice, if there are any changes necessary to unrelated parts like the documentation.
[**PLEASE SEE OUR SECURITY POLICY.**](SECURITY.md)
To set up a new notification provider these files need to be modified/created:
- `server/notification-providers/PROVIDER_NAME.js` is where the heart of the notification provider lives.
- Both `monitorJSON` and `heartbeatJSON` can be `null` for some events.
If both are `null`, this is a general testing message, but if just `heartbeatJSON` is `null` this is a certificate expiry.
- Please wrap the axios call into a
```js
try {
let result = await axios.post(...);
if (result.status === ...) ...
} catch (error) {
this.throwGeneralAxiosError(error);
}
```
- `server/notification.js` is where the backend of the notification provider needs to be registered.
*If you have an idea how we can skip this step, we would love to hear about it ^^*
- `src/components/NotificationDialog.vue` you need to decide if the provider is a regional or a global one and add it with a name to the respective list
- `src/components/notifications/PROVIDER_NAME.vue` is where the frontend of each provider lives.
Please make sure that you have:
- used `HiddenInput` for secret credentials
- included all the necessary helptexts/placeholder/.. to make sure the notification provider is simple to setup for new users.
- include all translations (`{{ $t("Translation key") }}`, [`i18n-t keypath="Translation key">`](https://vue-i18n.intlify.dev/guide/advanced/component.html)) in `src/lang/en.json` to enable our translators to translate this
- `src/components/notifications/index.js` is where the frontend of the provider needs to be registered.

Offering notifications is close to the core of what we are as an uptime monitor.
Therefore, making sure that they work is also really important.
Because testing notification providers is quite time intensive, we mostly offload this onto the person contributing a notification provider.
To make shure you have tested the notification provider, please include screenshots of the following events in the pull-request description:
- `UP`/`DOWN`
- Certificate Expiry via https://expired.badssl.com/
- Testing (the test button on the notification provider setup page)
Using the following way to format this is encouraged:
To set up a new notification provider these files need to be modified/created:
- `server/monitor-types/MONITORING_TYPE.js` is the core of each monitor.
the `async check(...)`-function should:
- throw an error for each fault that is detected with an actionable error message
- in the happy-path, you should set `heartbeat.msg` to a successfull message and set `heartbeat.status = UP`
- `server/uptime-kuma-server.js` is where the monitoring backend needs to be registered.
*If you have an idea how we can skip this step, we would love to hear about it ^^*
- `src/pages/EditMonitor.vue` is the shared frontend users interact with.
Please make sure that you have:

The following rules are essential for making your PR mergable:
- Merging multiple issues by a huge PR is more difficult to review and causes conflicts with other PRs. Please
- (if possible) **create one PR for one issue** or
- (if not possible) **explain which issues a PR addresses and why this PR should not be broken apart**
- Make sure your **PR passes our continuous integration**.
PRs will not be merged unless all CI-Checks are green.
- **Breaking changes** (unless for a good reason and discussed beforehand) will not get merged / not get merged quickly.
Such changes require a major version release.
- **Test your code** before submitting a PR.
Buggy PRs will not be merged.
- Make sure the **UI/UX is close to Uptime Kuma**.
- **Think about the maintainability**:
Don't add functionality that is completely **out of scope**.
Keep in mind that we need to be able to maintain the functionality.
- Don't modify or delete existing logic without a valid reason.
- Don't convert existing code into other programming languages for no reason.
I ([@louislam](https://github.com/louislam)) have the final say.
If your pull request does not meet my expectations, I will reject it, no matter how much time you spent on it.
Therefore, it is essential to have a discussion beforehand.
- A dedicated PR for translating existing languages (see [these instructions](https://github.com/louislam/uptime-kuma/blob/master/src/lang/README.md))
- Do not pass the auto-test
- Any breaking changes
- Duplicated pull requests
- Buggy
- UI/UX is not close to Uptime Kuma
- Modifications or deletions of existing logic without a valid reason.
- Adding functions that is completely out of scope
- Converting existing code into other programming languages
- Unnecessarily large code changes that are hard to review and cause conflicts with other PRs.
I will assign your pull request to a [milestone](https://github.com/louislam/uptime-kuma/milestones), if I plan to review and merge it.
The above cases may not cover all possible situations.
Please don't rush or ask for an ETA.
We have to understand the pull request, make sure it has no breaking changes and stick to the vision of this project, especially for large pull requests.

Also, please don't rush or ask for an 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.
We have found that assigning people to issues is management-overhead that we don't need.
A short comment that you want to try your hand at this issue is appreciated to save other devs time.
If you come across any problem during development, feel free to leave a comment with what you are stuck on.
### Recommended Pull Request Guideline
Before deep into coding, discussion first is preferred. Creating an empty pull request for discussion would be recommended.
Before diving deep into coding, having a discussion first by creating an empty pull request for discussion is preferred.
The rationale behind this is that we can align the direction and scope of the feature to eliminate any conflicts with existing and planned work, and can help by pointing out any potential pitfalls.
1. Fork the project
2. Clone your fork repo to local

The backend is an `express.js` server with `socket.io` integrated.
It uses `socket.io` to communicate with clients, and most server logic is encapsulated in the `socket.io` handlers.

## 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:
