Following samples are provided to demonstrate how to use FunctionGraph with Node.js:

General notes

Note

All samples are provided for demonstration purposes only. They may not cover all edge cases or best practices for production use. You can use these samples as a starting point and modify them according to your specific requirements and use cases.

The dependencies and dev dependencies used in the samples are file dependencies and are working if the complete repository is cloned.

To use the samples separately, you need to install the required dependencies and dev dependencies manually by running npm install in the sample directory.

For example, to install the dependencies for the scratch-event-apig sample, change

package.json

"dependencies": {
  "@opentelekomcloud-community/fg-apig-event": "file:../../fg-events/fg-apig-event"
},

to

package.json

"devDependencies": {
    "@opentelekomcloud-community/fg-context": "^1.0.0"
},
