Javascript Plugin

Javascript Plugin on Github

This example uses the Javascript and Request converter plugin. The first plugin adds a header and the request converter sends the whole request split into an object to the flow.

The flow receiving that request will have an additional header called Header1.

Javascript Route

direktiv_api: "endpoint/v1"
allow_anonymous: true
path: "/js"
methods:
  - "GET"
plugins:
  target:
    type: "target-flow"
    configuration:
      flow: "/js-plugin/wf.yaml"
      async: false
  inbound:
    - type: "js-inbound"
      configuration:
        script: |
          input["Headers"].Add("Header1", "Value1")
    - type: "request-convert"
      configuration:
        omit_headers: false
        omit_queries: false
        omit_body: false
        omit_consumer: false

Simple Workflow

direktiv_api: workflow/v1
states:
- id: helloworld
  type: noop
  transform:
    result: jq(.)

Advanced Example

This example uses a path parameter and a bit more complex Javascript.

• The plugin moves the original request in an object original
• The plugin gets the value of a query param action and puts it in action in the object

The URL would look like this: http://YOUR-SERVER/ns/examples/js-action?action=do-it

Advanced Javascript

direktiv_api: "endpoint/v1"
allow_anonymous: true
path: "/js-action"
methods:
  - "GET"
plugins:
  target:
    type: "target-flow"
    configuration:
      flow: "/js-plugin/wf.yaml"
      async: false
  inbound:
    - type: "js-inbound"
      configuration:
        script: |
          b = JSON.parse(input["Body"]) 
          const body = new Map();
          body['action'] = input["Queries"].Get("action")[0]
          body["original"] = b
          input["Body"] = JSON.stringify(body)
