## Why?

Building a web based medical imaging viewer from scratch is time intensive, hard
to get right, and expensive. Instead of re-inventing the wheel, you can use the
OHIF Viewer as a rock solid platform to build on top of. The Viewer is a
[React][react-url] [Progressive Web Application][pwa-url] that can be embedded
in existing applications via it's [packaged source
(ohif-viewer)][ohif-viewer-url] or hosted stand-alone. The Viewer exposes
[configuration][configuration-url] and [extensions][extensions-url] to support
workflow customization and advanced functionality at common integration points.

If you're interested in using the OHIF Viewer, but you're not sure it supports
your use case [check out our docs](https://docs.ohif.org/). Still not sure, or
you would like to propose new features? Don't hesitate to
[create an issue](https://github.com/OHIF/Viewers/issues) or open a pull
request.

## Getting Started

This readme is specific to testing and developing locally. If you're more
interested in production deployment strategies,
[you can check out our documentation on publishing](https://docs.ohif.org/).

### Setup

_Requirements:_

- [NodeJS & NPM](https://nodejs.org/en/download/)
- [Yarn](https://yarnpkg.com/lang/en/docs/install/)

_Steps:_

1. Fork this repository
2. Clone your forked repository (your `origin`)

- `git clone git@github.com:YOUR_GITHUB_USERNAME/Viewers.git`

3. Add `OHIF/Viewers` as a `remote` repository (the `upstream`)

- `git remote add upstream git@github.com:OHIF/Viewers.git`

### Developing Locally

In your cloned repository's root folder, run:

```js
// Restore dependencies
yarn install

// Stands up local server to host Viewer.
// Viewer connects to our public cloud PACS by default
yarn start
```

For more advanced local development scenarios, like using your own locally
hosted PACS and test data,
[check out our Essential: Getting Started](https://docs.ohif.org/essentials/getting-started.html)
guide.

### Contributing

> Large portions of the Viewer's functionality are maintained in other
> repositories. To get a better understanding of the Viewer's architecture and
> "where things live", read
> [our docs on the Viewer's architecture](https://docs.ohif.org/advanced/architecture.html#diagram)

It is notoriously difficult to setup multiple dependent repositories for
end-to-end testing and development. That's why we recommend writing and running
unit tests when adding and modifying features. This allows us to program in
isolation without a complex setup, and has the added benefit of producing
well-tested business logic.

1. Clone this repository
2. Navigate to the project directory, and `yarn install`
3. To begin making changes, `yarn run dev`
4. To commit changes, run `yarn run cm`

When creating tests, place the test file "next to" the file you're testing.
[For example](https://github.com/OHIF/Viewers/blob/master/src/utils/index.test.js):

```js
// File
index.js

// Test for file
index.test.js
```

As you add and modify code, `jest` will watch for uncommitted changes and run
your tests, reporting the results to your terminal. Make a pull request with
your changes to `master`, and a core team member will review your work. If you
have any questions, please don't hesitate to reach out via a GitHub issue.
