DevWorkspace Generator

The library is used by Eclipse Che to generate DevWorkspace components and templates. It requires both the original devfile.yaml and the editor definitions.

Where is it Published?

This library is available on npm.

You can find the published package here:
npm: @eclipse-che/che-devworkspace-generator

Usage

Here’s an example of how to use the @eclipse-che/che-devworkspace-generator library to generate a DevWorkspace and DevWorkspaceTemplate:

import { Main as DevworkspaceGenerator } from '@eclipse-che/che-devworkspace-generator/lib/main';
import { V1alpha2DevWorkspaceTemplate } from '@devfile/api';
import { dump } from 'js-yaml';

// Initialize the DevWorkspace generator
const generator = new DevworkspaceGenerator();

// Example function to generate DevWorkspace resources
async function generateDevWorkspace(devfileContent: string, editorContent: string, axiosInstance: any) {
  // Generate the Devfile context
  const context = await generator.generateDevfileContext(
    {
      devfileContent,
      editorContent,
      projects: [],
    },
    axiosInstance,
  );

  // Convert templates and DevWorkspace to YAML
  const allContentArray = context.devWorkspaceTemplates.map(
    (template: V1alpha2DevWorkspaceTemplate) => dump(template),
  );
  allContentArray.push(dump(context.devWorkspace));

  // Return the YAML content joined by "---"
  return allContentArray.join('---\n');
}

The library can be used as a standalone library:

USAGE
    $ node lib/entrypoint.js [OPTIONS]

OPTIONS
      --devfile-url:           URL to the git repository that contains devfile.yaml
            or
      --devfile-path:          path to the devfile.yaml file

      --editor-url:            URL for the editor's definition, should be publicly accessible for download.
            or
      --editor-path:           local file path of the editor devfile.yaml
            or
      --editor-content:        content of the editor devfile.yaml

      --output-file:           local file path for the generated devworkspace yaml 

      --project.<project-name> local file path for the sample project zip (for airgapped/offline registry builds)

      --injectDefaultComponent: inject a default dev container component if no component is defined in the devfile and it doesn't provide a parent, the value can be true or false, default is false

      --defaultComponentImage: image to use for the default dev container component that will be injected if no componetn is defined in the devfile and it doesn't provide a parent devfile, default is quay.io/devfile/universal-developer-image:ubi8-latest

EXAMPLES

    # online example, using editor definition from https://raw.githubusercontent.com/eclipse-che/che-operator/refs/heads/main/editors-definitions/che-code-insiders.yaml

    $ node lib/entrypoint.js \
        --devfile-url:https://github.com/che-samples/java-spring-petclinic/tree/main \
        --editor-url:https://raw.githubusercontent.com/eclipse-che/che-operator/refs/heads/main/editors-definitions/che-code-insiders.yaml \
        --output-file:/tmp/devworkspace-che-code-latest.yaml \
        --injectDefaultComponent:true \
        --defaultComponentImage:registry.access.redhat.com/ubi8/openjdk-11:latest

    # offline example with devfile.yaml files and zipped project available locally

    $ node lib/entrypoint.js \
        --devfile-path:/remote-source/python-hello-world/app/devfile.yaml \
        --editor-path:/build/plugins/che-incubator/che-code/latest/devfile.yaml \
        --output-file:./devfiles/python__python-hello-world/devworkspace-che-code-latest.yaml \
        --project.python-hello-world='{{_INTERNAL_URL_}}/resources/v2/python-hello-world.zip'

The output file devworkspace-che-code-latest.yaml contains a DevWorkspace based on the repository devfile and a Che-Code DevWorkspaceTemplate.

If the DevWorkspace engine is installed on the cluster, the following command will create a DevWorkspace:

$ kubectl apply -f /tmp/devworkspace-che-code-latest.yaml
