@ohif/core

@ohif/core is a collection of useful functions and classes for building web-based medical imaging applications. This library helps power OHIF's zero-footprint DICOM viewer.

This library offers pre-packaged solutions for features common to Web-based medical imaging viewers. For example: - Hotkeys - DICOM Web - Hanging Protocols - Managing a study's measurements - Managing a study's DICOM metadata - A flexible pattern for extensions - And many others It does this while remaining decoupled from any particular view library or rendering logic. While we use it to power our [React Viewer][react-viewer], it can be used with Vue, React, Vanilla JS, or any number of other frameworks. ## Getting Started The documentation for this library is sparse. The best way to get started is to look at its [top level exports](https://github.com/OHIF/Viewers/blob/master/platform/core/src/index.js), and explore the source code of features that interest you. If you want to see how we use this library, you can check out [our viewer implementation][react-viewer]. ### Install > This library is pre- v1.0. All releases until a v1.0 have the possibility of > introducing breaking changes. Please depend on an "exact" version in your > projects to prevent issues caused by loose versioning. ``` // with npm npm i @ohif/core --save-exact // with yarn yarn add @ohif/core --exact ``` ### Usage Usage is dependent on the feature(s) you want to leverage. The bulk of `@ohif/core`'s features are "pure" and can be imported and used in place. _Example: retrieving study metadata from a server_ ```js import { studies } from '@ohif/core'; const studiesMetadata = await studies.retrieveStudiesMetadata( server, // Object studyInstanceUIDs, // Array seriesInstanceUIDs // Array (optional) ); ``` ### Contributing 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 for this library. 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 --frozen-lockfile` 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/ohif-core/blob/master/src/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. ## Contributors Thanks goes to these wonderful people ([emoji key](https://allcontributors.org/docs/en/emoji-key)):
