Development environment

This page will walk you through the development workflow when using an in-platform VS Code workspace to build OSDK React applications.

Get started

After following the steps to set up your Developer Console, you can start developing in your code environment. To use a VS Code workspace, select Create code repository under the Code Repository section in the left side panel. This action will bootstrap your repository with the default React template. You can then select Open in VS Code to launch an in-platform workspace.

The repository template will include a basic React application integrated with authorization and the Ontology SDK.

Development lifecycle

Once the VS Code Workspace is launched, you should see the code editor on the left and a live preview of your application on the right. You can start editing your code as if working in a local environment.

The VS Code Workspace landing page.

Edit

You can now start building your React application. Be sure to edit and test your code after writing, then use git commands or the VS Code interface to commit and push your changes to make them visible to other developers in your project. In the terminal, run npm run lint, npm run test, and npm run build to ensure that checks will succeed.

You can also refer to the Ontology tab in the left side panel to view generated documentation and code snippets for your OSDK and return to Developer Console.

Deploy

To deploy a React application, you must first cut a release. This is commonly done with the git tag command, where you can set the version number and then push it to your repository:

Copied!
1 2 git tag <x.y.z> git push origin tag

Alternatively, you can cut a release from within the Code Repositories interface by selecting Open in Code Repositories from the top right corner of the screen. Navigate to the the Version control tab, the open the Tags and releases section to view previous releases and cut a new release.

The "Tags and releases" section of the "Version control" tab in Code Repositories.

Once the release passes checks, you will be able to view your application in Developer Console.

Content Security Policy

By default, we apply a restrictive Content Security Policy (CSP). This means a request to non-Foundry URIs will fail and must be explicitly allowed.

To detect a CSP error, select <F12> and review logs inside the console. If you have CSP failures, you will see errors similar to those shown below:

You can apply a temporary CSP to your VS Code workspace. For security reasons, this CSP will not apply to other users of this workspace and will expire when the workspace is paused or restarted.

After testing your application inside the VS Code workspace, ensure that the CSP is updated for your Developer Console application.

Development tips

To Do application tutorial

If you are new to Developer Console and OSDK, we recommend following one of our tutorials to get started. Navigate to the Build with AIP application in your enrollment and install one of our example workflows.

Progressive Web Application (PWA)

For an optimized editing experience, you can choose to install your workspace as a Progressive Web Application (PWA). A PWA will accept some commonly used shortcuts, such as Cmd+W (macOS) to close a tab.

Zen mode

For a nearly native VS Code experience, we recommend using Zen mode. Select View > Activate Zen mode to enable. Zen mode will hide the platform interface and make VS Code take up the entire browser window. To exit Zen mode, hover over the three dots ... in the top center of your screen.

Local development

Instead of working inside the platform, you can work locally on your machine in the following ways:

  • Navigate to your repository in the Code Repositories application, then select Work locally in the top right corner of your screen to clone your repository and export the FOUNDRY_TOKEN to your local environment.

Refer to the readme.md file in the repository for more information.

You can store your repository outside the Palantir platform while still using the Developer Console to deploy the application. Learn mode in our documentation on deploying an Ontology SDK application on Foundry.
