---

## New contributor guide

To get an overview of the project, read the [README](README.md). Here are some resources to help you get started with open source contributions:

- [Set up Git](https://docs.github.com/en/get-started/quickstart/set-up-git)
- [GitHub flow](https://docs.github.com/en/get-started/quickstart/github-flow)
- [Collaborating with pull requests](https://docs.github.com/en/github/collaborating-with-pull-requests)

## Getting started

### Issues

#### Create a new issue

If you spot a problem with entsoe-api-client, [search if an issue already exists](https://docs.github.com/en/github/searching-for-information-on-github/searching-on-github/searching-issues-and-pull-requests#search-by-the-title-body-or-comments). If a related issue doesn't exist, you can open a new issue using a relevant [issue form](https://github.com/hexagon/entsoe-api-client/issues/new/choose). 

#### Solve an issue

Scan through our [existing issues](https://github.com/hexagon/entsoe-api-client/issues) to find one that interests you. You can narrow down the search using `labels` as filters. If you find an issue to work on, make a note in the comments so er van assign it to you. Then you are welcome to open a PR with a fix.

### Make Changes

#### Setting up the environment

We recommend using VS Code with the deno extensions, which will automatically check your code against the defined rules as you write it.

1. Fork the repository.
- Using GitHub Desktop:
  - [Getting started with GitHub Desktop](https://docs.github.com/en/desktop/installing-and-configuring-github-desktop/getting-started-with-github-desktop) will guide you through setting up Desktop.
  - Once Desktop is set up, you can use it to [fork the repo](https://docs.github.com/en/desktop/contributing-and-collaborating-using-github-desktop/cloning-and-forking-repositories-from-github-desktop)!

- Using the command line:
  - [Fork the repo](https://docs.github.com/en/github/getting-started-with-github/fork-a-repo#fork-an-example-repository) so that you can make your changes without affecting the original project until you're ready to merge them.

2. Install **Deno** 

3. Install or update to **Node.js v18** (node is used for generating and testing the node-part of the module) 

4. Create a working branch ```feature/my-cool-feature``` or ```bugfix/issue-14``` and start with your changes!

### Commit your update

Please run ```deno task precommit``` before committing, to make sure every test and check passes.

See the scripts section of [/deno.jsonc](https://github.com/Hexagon/entsoe-api-client/blob/main/deno.jsonc) int the GitHub repository for all available scripts.

Then, commit the changes once you are happy with them. 

### Updating dependencies

If you're updating dependencies, use `deno task update-deps` to check for the latest versions. Then update `deps.ts`, `scripts/deps.ts` and finally update any mapping in `scripts/build_npm.ts`.

### Pull Request

When you're finished with the changes, create a pull request, also known as a PR.
- Don't forget to [link PR to issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue) if you are solving one.
- Enable the checkbox to [allow maintainer edits](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/allowing-changes-to-a-pull-request-branch-created-from-a-fork) so the branch can be updated for a merge.
Once you submit your PR, a team member will review your proposal. We may ask questions or request for additional information.
- We may ask for changes to be made before a PR can be merged, either using [suggested changes](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/incorporating-feedback-in-your-pull-request) or pull request comments. You can apply suggested changes directly through the UI. You can make any other changes in your fork, then commit them to your branch.
- As you update your PR and apply changes, mark each conversation as [resolved](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/commenting-on-a-pull-request#resolving-conversations).
- If you run into any merge issues, checkout this [git tutorial](https://lab.github.com/githubtraining/managing-merge-conflicts) to help you resolve merge conflicts and other issues.
