* fix: Use correct default for dev builds app config

* chore: restore pnpm-lock.yaml to match master

The lockfile diff was incidental peer-descriptor churn and carried no
functional dependency change. It tripped the CircleCI security-audit gate
(which only runs when pnpm-lock.yaml is in the PR diff), surfacing a
pre-existing critical `decompress` transitive vuln that also exists on
master. Restoring master's lockfile removes the audit trigger.

* fix(ci): restore json5 lockfile entry; ignore unfixable decompress GHSA

The previous commit restored pnpm-lock.yaml from master, which dropped the
json5@2.2.3 entry that platform/core legitimately depends on (JSONC parsing
for the customization feature). That broke `--frozen-lockfile` install
(ERR_PNPM_OUTDATED_LOCKFILE). This restores the correct lockfile.

Because the lockfile must change (json5), the CircleCI security-audit gate
runs and previously failed on a critical `decompress` <=4.2.1 zip-slip
advisory. This is a pre-existing transitive vuln (present on master too) with
no published patch — decompress's latest release is 4.2.1, so no version
bump/override can resolve it. It reaches the tree only via @itk-wasm/dam, a
build/data-asset extraction tool under @cornerstonejs/labelmap-interpolation.

Add GHSA-mp2f-45pm-3cg9 to the existing pnpm-workspace.yaml auditConfig
ignoreGhsas accepted-risk list, matching how the repo already exempts other
build-tooling advisories. `pnpm audit --audit-level high` now passes locally
(1 critical ignored, 0 high).

* test(e2e): fix visitStudy URL encoding that broke mpr2 study load

The visitStudy rewrite (added for the ?customization= option) built the URL
with new URLSearchParams({ StudyInstanceUIDs: studyInstanceUID }), which
percent-encodes the value. mpr2.spec.ts embeds an extra param in the UID
string ('<uid>&hangingprotocolid=mpr'), so the & and = were encoded and the
whole thing collapsed into one invalid StudyInstanceUIDs value -> the study
could not be found ('studies are not available'), the viewer never rendered,
and the side-panel-header-right click timed out.

Restore master's raw concatenation for StudyInstanceUIDs (so embedded params
survive as separate query params) while still appending the customization
option separately. Only mpr2 embeds & in the UID, matching the single failure.

@ohif/app

@ohif/app is a zero-footprint medical image viewer provided by the Open Health Imaging Foundation (OHIF). It is a configurable and extensible progressive web application with out-of-the-box support for image archives which support DICOMweb.


NPM version NPM downloads Pulls All Contributors MIT License

ATTENTION: If you are looking for Version 1 (the Meteor Version) of this repository, it lives on the v1.x branch

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 Progressive Web Application that can be embedded in existing applications via it's packaged source (ohif-viewer) or hosted stand-alone. The Viewer exposes configuration and extensions 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. Still not sure, or you would like to propose new features? Don't hesitate to create an issue 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.

Want to play around before you dig in? Check out our LIVE Demo

Setup

Requirements:

Steps:

  1. Fork this repository
  2. Clone your forked repository (your origin)
  • git clone git@github.com:YOUR_GITHUB_USERNAME/Viewers.git
  1. 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:

// Restore dependencies
yarn install --frozen-lockfile

// 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 guide.

E2E Tests

Using Cypress to create End-to-End tests and check whether the application flow is performing correctly, ensuring that the integrated components are working as expected.

Why Cypress?

Cypress is a next generation front end testing tool built for the modern web. With Cypress is easy to set up, write, run and debug tests

It allow us to write different types of tests:

  • End-to-End tests
  • Integration tests
  • Unit tets

All tests must be in ./cypress/integration folder.

Commands to run the tests:

// Open Cypress Dashboard that provides insight into what happened when your tests ran
yarn run cy

// Run all tests using Electron browser headless
yarn run cy:run

// Run all tests in CI mode
yarn run cy:run:ci

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

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:

// 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.
