# MinIO Console Server Contribution Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

This is a REST portal server created using [go-swagger](https://github.com/go-swagger/go-swagger)

The API handlers are created using a YAML definition located in `swagger.YAML`.

To add new api, the YAML file needs to be updated with all the desired apis using the [Swagger Basic Structure](https://swagger.io/docs/specification/2-0/basic-structure/), this includes paths, parameters, definitions, tags, etc.

## Generate server from YAML
Once the YAML file is ready we can autogenerate the code needed for the new api by just running:

Validate it:
```
swagger validate ./swagger.yml
```
Update server code:
```
make swagger-gen
```

This will update all the necessary code.

`./restapi/configure_console.go` is a file that contains the handlers to be used by the application, here is the only place where we need to update our code to support the new apis. This file is not affected when running the swagger generator and it is safe to edit.

## Unit Tests
`./restapi/handlers_test.go` needs to be updated with the proper tests for the new api.

To run tests:
```
go test ./restapi
```

## Commit changes
After verification, commit your changes. This is a [great post](https://chris.beams.io/posts/git-commit/) on how to write useful commit messages

```
$ git commit -am 'Add some feature'
```

### Push to the branch
Push your locally committed changes to the remote origin (your fork)
```
$ git push origin my-new-feature
```

### Create a Pull Request

## FAQs
### How does ``console`` manages dependencies?
``MinIO`` uses `go mod` to manage its dependencies.
- Run `go get foo/bar` in the source folder to add the dependency to `go.mod` file.

To remove a dependency
- Edit your code and remove the import reference.
- Run `go mod tidy` in the source folder to remove dependency from `go.mod` file.

### What are the coding guidelines for console?
``console`` is fully conformant with Golang style. Refer: [Effective Go](https://github.com/golang/go/wiki/CodeReviewComments) article from Golang project. If you observe offending code, please feel free to send a pull request or ping us on [Slack](https://slack.min.io).
