Build for Production

Build Machine Requirements#

Getting the Code#

With Git:

# Clone the remote repository to your local machinegit clone https://github.com/OHIF/Viewers.git

More on: git clone, git checkout

From .zip:

OHIF/Viewers: master.zip

Restore Dependencies & Build#

Open your terminal, and navigate to the directory containing the source files. Next run these commands:

# If you haven't already, enable yarn workspacesyarn config set workspaces-experimental true
# Restore dependenciesyarn install
# Build source code for productionyarn run build

If everything worked as expected, you should have a new dist/ directory in the platform/viewer/dist folder. It should roughly resemble the following:

<root>platform/viewer/dist/
├── app-config.js├── app.bundle.js├── app.css├── index.html├── manifest.json├── service-worker.js└── ...

By default, the build output will connect to OHIF's publicly accessible PACS. If this is your first time setting up the OHIF Viewer, it is recommended that you test with these default settings. After testing, you can find instructions on how to configure the project for your own imaging archive below.

Configuration#

The configuration for our viewer is in the <root>platform/viewer/public/config directory. Our build process knows which configuration file to use based on the APP_CONFIG environment variable. By default, its value is [config/default.js][default-config]. The majority of the viewer's features, and registered extension's features, are configured using this file.

The easiest way to apply your own configuration is to modify the default.js file. For more advanced cofiguration options, check out our configuration essentials guide.

Testing Build Output Locally#

A quick way to test your build output locally is to spin up a small webserver. You can do this by running the following commands in the dist/ output directory:

# Install http-server as a globally available packageyarn global add http-server
# Change the directory to the platform/viewer
# Serve the files in our current directory# Accessible at: `http://localhost:8080`npx http-server ./dist

Automating Builds and Deployments#

If you found setting up your environment and running all of these steps to be a bit tedious, then you are in good company. Thankfully, there are a large number of tools available to assist with automating tasks like building and deploying web application. For a starting point, check out this repository's own use of:
