ActionStep TypeScript API Client

Installation

Client SDK

For accessing ActionStep data:

npm install @dbc-tech/actionstep

Azure Functions Token Service

For implementing a persistent token store using Azure Functions:

npm install @dbc-tech/actionstep-auth-function

Using Client SDK

To use the SDK, an access token is required and because this is short-lived, a token client is created which is passed to the SDK so that each request can obtain a new (or refreshed) token.

Two token clients are provided: actionStepTokenClient and actionStepLegacyTokenClient. actionStepTokenClient is typically used when hosting your token service on Azure, using the @dbc-tech/actionstep-auth-function package and actionStepLegacyTokenClient is used for previous-generation token services which return the token in a slightly different shape. You can of course create your own implementation of ActionStepTokenClient to obtain a token by other means.

Either way, create an instance of your token client and pass in the url of the service which is providing the token, and the ActionStep API URL:

import { actionStepTokenClient } from '@dbc-tech/actionstep'

const tokenClient = actionStepTokenClient(
  process.env.ACTIONSTEP_TOKEN_URL,
  process.env.ACTIONSTEP_API_URL,
)

Important: ActionStep has some inconsistencies with API urls and paths found in their OpenAPI specs. An example spec path would be /actions/{id}. However, this endpoint is actually served up through https://ap-southeast-2.actionstep.com/api/rest/actions/{id}. Therefore, the API url should be: https://ap-southeast-2.actionstep.com/api/rest and not https://ap-southeast-2.actionstep.com/api which is often returned in the access token. Be sure your API url ends with /rest.

With the token client you can now create an instance of the actionStepClient:

import { actionStepTokenClient, actionStepClient } from '@dbc-tech/actionstep'

const client = actionStepClient(tokenClient)

ActionStep APIs are split over multiple endpoint groups. Each group is accessed through the client and can be destructured for convenience. For example, to access the actions endpoint group:

const { actions: actionsClient } = actionStepClient(tokenClient)

Example

get actions reads all actions one page at a time. Use params to specify the page number and number of items per page as documented here.

const { data, error } = await actionsClient.getActions({
  page: 1,
  pageSize: 10,
  filter: "status ilike '%active%'"
})
if (error) console.error('error:', error)
else {
  for (const action of data.actions) {
    console.log('get action:', {
      id: action.id,
      name: action.name,
      reference: action.reference,
    })
  }
}

As a response could contain an error, it is important first to check the error status. Note: data and error are mutually exclusive. If there is no error then the data shape will match that described in the API documentation. In this case an array of actions is found under the actions property.

Testing endpoints

A sandbox project is available to test individual endpoints. See readme for more information.

Building Source

1. Install or update nvm

   nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and windows WSL.

2. Open the shell and change to the monorepo workspace root directory.

   cd monorepo

3. Install and activate the indicated Node.js version in .nvmrc

   nvm install

4. Switch to the Node.js version specified in .nvmrc in the current shell. You should run this every time you open a new shell.

   nvm use
   node -v

5. To avoid running nvm use for each shell, you can set the system default Node.js version as indicated in the .nvmrc. Run the following and restart your shell

   nvm alias default "$(<.nvmrc)"

6. Install packages

   npm install

7. Build

   npm run build

8. To run the unit tests

   npm test
