A fake AP module to help develop and test Atlassian Connect applications.

Atlassian Connect apps often use the Atlassian Connect JavaScript API, also called AP, to overcome the limitations due to the app existing in an iframe from an Atlassian page.

AP is typically included by calling the following script:

<script src="https://connect-cdn.atl-paas.net/all.js"></script>

However this script only work when in an iframe from an Atlassian page. It means that when developing or testing, it is not possible to directly call the page if it is using AP.

This package provides a way to make a fake AP that can be used instead of the real one. It includes the most commonly used features of AP, including:

• Generating JWT tokens
• Dialogs
• Events
• Flags
• History
• Request
• User locale

Note: This package should never be used on a production environment.

Using npm:

npm install --save-dev @smartbear/fake-ap

Using yarn:

yarn add -D @smartbear/fake-ap

Simply create a Fake AP instance an make it available globally:

import FakeAP from '@smartbear/fake-ap'

window.AP = new FakeAP()

The fake AP creation should be done in a script included instead of the real one. For instance, in for the project fake AP was originally created for, the script is available as a pack which is included when a flag is set. Here is an example using Rails and Webpacker:

<% if ENV['USE_FAKE_AP'] %>
  <%= javascript_pack_tag 'fake_ap' %>
<% else %>
  <script src="https://connect-cdn.atl-paas.net/all.js"></script>
<% end %>

While most features work with no configuration, some methods require configuration to tell our fake AP which values to deal with. Configuration can be done when creating the fake AP, or at any time later using the special AP.configure method:

const AP = new FakeAP({
  locale: 'en_US'
})

AP.configure({
  locale: 'fr_FR'
})

Here is a list of all available configuration (refer to their own section for details):

Note: when using AP.configure, all previous configuration is kept, only conflicting configuration is replaced. All new configuration is added.

To use AP.context.getToken, which creates a valid JWT token as Atlassian would do, it is required to provide the tenant client key and shared secret, as well as a user ID:

AP.configure({
  clientKey: 'key',
  sharedSecret: 'secret',
  userId: 'user'
})

You can also configure a context that will be added to the payload (see AP.context.getContext). By default that context is an empty object.

To use AP.context.getContext, you can provide a context object to the configuration:

AP.configure({
  context: {
    jira: {
      project: {
        id: '10000'
      }
    }
  }
})

By default the context is an empty object. The same context will also be added to the payload of AP.context.getToken.

To use dialogs (AP.context.create), you need to provide the dialog keys and URLs as they are describe in the descriptor:

AP.configure({
  dialogUrls: {
    'custom-dialog': 'https://localhost:3000/dialog'
  }
})

AP.dialog.create({
  key: 'custom-dialog'
})

You can specify the user locale (defaults to en_US):

AP.configure({
  locale: 'fr_FR'
})

AP.request is the most complex to implement. Because of same-origin policy, it is not possible to implement a native request method using a shared secret configuration. Since several solutions are possible to work around this limitation, adapters have been designed to provide a request method.

If you do not specify any adapter, the default behavior when using AP.request is to do nothing. It will just call the notImplementedAction method if provided:

AP.configure({
  notImplementedAction: console.log
})

// This will call console.log('AP.request', 'path', { method: 'POST' })
AP.request('path', { method: 'POST' })

The backend adapter is a way to make actual requests to the Jira API using your own backend. It requires some work from the backend though:

• Implement a Jira client to interact with the Jira API
• Provide an API endpoint for the fake AP to call

This API endpoint should not require any authentication method, as the adapter does not provide any. For obvious reasons, ensure that this API endpoint is never available on production.

Backend adapter should be configured like this:

import FakeAP, { BackendRequestAdapter } from '@smartbear/fake-ap'

const backendRequestAdapter = new BackendRequestAdapter('/path/to/fake_ap/api')

const AP = new FakeAP({
  requestAdapter: backendRequestAdapter
})

Then a POST request to the backend API will be made using the AP.request options. For instance, consider following request:

AP.request(
  '/rest/api/3/search',
  {
    data: { some: 'data' }
  }
)

This will make a POST request to your backend with a request body containing:

• method = GET
• path = '/rest/api/3/search'
• data = { some: 'data' }

To make this adapter as generic as possible, there is no additional information sent to the backend. If you need to know which tenant is this request for, you need to specify it with the configuration URL. For instance:

AP.configure({
  requestAdapter: new BackendRequestAdapter('/path/to/fake_ap/api/tenants/2')
})

It is possible to create a custom adapter by extending from the default adapter:

import { RequestAdapter } from '@smartbear/fake-ap'

class CustomAdapter extends RequestAdapter {
  async request() {
    return {
      body: '{}'
    }
  }
}

Here are the specifications for a custom adapter:

• Extend from RequestAdapter
• Implement a request method that is async (or returns a promise)
• If the request is a success, request should return an object with a body property that contained the JSON response as a string
• If the request is a failure, request should throw the response body with a specific object:

  // Assuming the response body was '{}' and status was 400
  {
    err: '{}',
    xhr: {
      responseText: '{}',
      status: 400,
      statusText: 'Bad Request'
    }
  }

It is possible to configure the behavior of AP methods that are not implemented in fake AP:

AP.configure({
  notImplementedAction: console.log
})

When called, any method that is not implemented will call the notImplementedAction method with the method name and all the arguments. Using the above configuration, calling AP.context.getContext('a', 'b') will call console.log('AP.context.getContext', 'a', 'b'). It is possible to have more advanced behaviors:

// This will forward all arguments to console.log, but will silence AP.resize calls
AP.configure({
  notImplementedAction: (method, ...args) => {
    if (method !== 'AP.resize') {
      console.log(method, ...args)
    }
  }
})

When a method requires some configuration that is not provided (for instance AP.context.getToken), Fake AP will throw an error by default. It is possible to change this behavior:

AP.configure({
  clientKey: 'key',
  userId: 'user',
  missingConfigurationAction: console.log
})

// This will call console.log('AP.context.getToken', 'sharedSecret', callback)
const callback = () => {}
await AP.context.getToken(callback)

To make dialogs and flags work, Fake AP will create and mount React components in the document body. If you do not want this to happen (to keep your DOM clean during unit tests for instance), you can disable dialogs and flags:

const AP = new FakeAP({
  mountDialogs: false,
  mountFlags: false
})

No error will be raised, but nothing will happen since the components will not exist.

Note: this can only be configured when creating the Fake AP. AP.configure will have no effect here since the components are already mounted.

• AP.context:
  • getToken
  • getContext
• AP.dialog:
  • create
  • close
  • getCustomData
• AP.event:
  • on
  • once
  • off
  • emit
• AP.flag.create
• AP.history:
  • getState
  • popState
  • pushState
  • replaceState
• AP.request
• AP.user.getLocale

Note: AP.dialog.create does not handle every options. It handles the key option properly, but will show a dialog as if the options were:

{
  width: '100%',
  height: '100%',
  chrome: false
}

Fake AP is still missing a lot of methods from the actual AP:

• AP.cookie
• AP.dialog:
  • getButton
  • disableCloseOnSubmit
  • createButton
  • isCloseOnEscape
• AP.event: all any and public events
• AP.history:
  • back
  • forward
  • go
• AP.host
• AP.iframe: AP.resize and AP.sizeToParent
• AP.inlineDialog
• AP.jira
• AP.navigator
• AP.user:
  • getCurrentUser
  • getTimeZone

Some methods like AP.resize do not really make sense in a development or testing environment, so they may not be implemented before a long time.

Once Fake AP is created, it is possible to add any custom implementation that is specific to your application.

The example below is a custom implementation of AP.navigator.go. It checks that you are on a specific page (/normal_page) and are trying to navigate to an issue. If it is the case it will check the correct issue ID using AP.request, then redirect to the correct page using that issue ID.

AP.navigator.go = async (target, context) => {
  if (target === 'issue' && window.location.pathname === '/normal_page') {
    const response = await AP.request(`/rest/api/3/issue/${context.issueKey}`)
    const issueId = JSON.parse(response.body).id

    window.location = `/issue_page?issueId=${issueId}`
  }
}
