@backstage/plugin-scaffolder-backend-module-confluence-to-markdown

Welcome to the confluence:transform:markdown action for the scaffolder-backend.

Getting started

The following sections will help you getting started

Configure Action in Backend

From your Backstage root directory run:

# From your Backstage root directory
yarn --cwd packages/backend add @backstage/plugin-scaffolder-backend-module-confluence-to-markdown

Then configure the action: (you can check the docs to see all options):

// packages/backend/src/plugins/scaffolder.ts

import { createBuiltinActions } from '@backstage/plugin-scaffolder-backend';
import { ScmIntegrations } from '@backstage/integration';
import { createConfluenceToMarkdownAction } from '@backstage/plugin-scaffolder-backend-module-confluence-to-markdown';

export default async function createPlugin(
  env: PluginEnvironment,
): Promise<Router> {
  const catalogClient = new CatalogClient({ discoveryApi: env.discovery });
  const integrations = ScmIntegrations.fromConfig(env.config);

  const builtInActions = createBuiltinActions({
    integrations,
    catalogClient,
    config: env.config,
    reader: env.reader,
  });

  const actions = [
    ...builtInActions,
    createConfluenceToMarkdownAction({
      integrations,
      config: env.config,
      reader: env.reader,
    }),
  ];

  return createRouter({
    actions,
    catalogClient: catalogClient,
    logger: env.logger,
    config: env.config,
    database: env.database,
    reader: env.reader,
  });
}

Configuration

There is some configuration that needs to be setup to use this action, these are the base parameters:

confluence:
  baseUrl: 'https://confluence.example.com'
  auth:
    token: '${CONFLUENCE_TOKEN}'

The sections below will go into more details about the Base URL and Auth Methods.

Base URL

The baseUrl for Confluence Cloud should include the product name which is wiki by default but can be something else if your Org has changed it. An example baseUrl for Confluence Cloud would look like this: https://example.atlassian.net/wiki

If you are using a self-hosted Confluence instance this does not apply to you. Your baseUrl would look something like this: https://confluence.example.com

Auth Methods

The default authorization method is bearer but basic and userpass are also supported. Here's how you would configure each of these:

For bearer:

confluence:
  baseUrl: 'https://confluence.example.com'
  auth:
    type: 'bearer'
    token: '${CONFLUENCE_TOKEN}'

For basic:

confluence:
  baseUrl: 'https://confluence.example.com'
  auth:
    type: 'basic'
    token: '${CONFLUENCE_TOKEN}'
    email: '[e-mail]'

For userpass

confluence:
  baseUrl: 'https://confluence.example.com'
  auth:
    type: 'userpass'
    username: 'your-username'
    password: 'your-password'

Note: For basic and bearer authorization methods you will need an access token for authorization with Read permissions. You can create a Personal Access Token (PAT) in Confluence. The value used should be the raw token as it will be encoded for you by the action.

Template Usage
