JIRA addon for Storybook

This addon makes JIRA ticket information visible and linked within your stories.

Usage

Just add the ticket ID as a parameter to your component story like this:

export default {
  title: "Example/Button",
  component: Button,
  parameters: {
    jira: {
      id: 'RING-1020'
    }
  },
};

Installation

1. To add this addon to your storybook configuration, first run yarn add storybook-jira-addon.

2. Then add it to the addons array in main.js:

   addons: [
     "storybook-jira-addon"
   ],

3. You will need to add the following values to your .env file.:

   `STORYBOOK_JIRA_API_ENDPOINT`

   This will be the API endpoint for obtaining ticket data from JIRA. This will be something like: `https://.atlassian.net/rest/api/latest/issue`
   `STORYBOOK_JIRA_USERNAME`

   This will be your username for logging in to JIRA. Most of the times it will just be your email address.
   `STORYBOOK_JIRA_API_KEY`

   To use this addon, you will need to generate an API token for your JIRA account. This can be acquired [here](https://id.atlassian.com/manage-profile/security/api-tokens).
   `STORYBOOK_JIRA_BASE_URL`

   This will be something like: `https://.atlassian.net/browse`.

4. Within storybook you then need to run some middleware to set up the api. To do this, add a middleware.js file in your .storybook folder. To use basic authentication this file then needs to contain the following code:

   const fetch = require("node-fetch");
   
   module.exports = function expressMiddleware (router) {
     router.get('/api', (req, res) => {
   
         const myHeaders = new fetch.Headers();
         const authHeader = `Basic ${Buffer.from(`${process.env?.STORYBOOK_JIRA_USERNAME}:${process.env?.STORYBOOK_JIRA_API_KEY}`).toString('base64')}`
         myHeaders.append("Authorization", authHeader);
   
         const requestOptions = {
           method: 'GET',
           headers: myHeaders,
           redirect: 'follow'
         };
   
         fetch(`${process.env.STORYBOOK_JIRA_API_ENDPOINT}/${req.query?.ticketId}`, requestOptions)
           .then(response => response.json())
           .then(result => {
             res.send(result)
           })
           .catch(error => console.log('error', error));
     })
   }

   Alternatively you can set up authentication using OAuth as is described here.

   You might need to still add node-fetch to your dev dependencies by running yarn add node-fetch -D.

Deploying to netlify

When deploying to netlify, you can get the addon working by adding a serverless function.

To do this I recommend taking the steps below:

1. Create a new file called netlify/functions/get-ticket-data.js

   Creating this file in a different folder is possible, but requires additional configuration in the Netlify UI.

2. add the code below to get-ticket-data.js:

const fetch = require('node-fetch');

exports.handler = async function (event, context) {
  
  const myHeaders = new fetch.Headers();
  const authHeader = `Basic ${Buffer.from(`${process.env.STORYBOOK_JIRA_USERNAME}:${process.env.STORYBOOK_JIRA_API_KEY}`).toString('base64')}`
  myHeaders.append("Authorization", authHeader);

  const requestOptions = {
    method: 'GET',
    headers: myHeaders,
    redirect: 'follow'
  };

  const ticketData = await fetch(`${process.env.STORYBOOK_JIRA_API_ENDPOINT}/${event.queryStringParameters.ticketId}`, requestOptions)
  .then(response => response.text())
  .then(result => {
    return result
  })
  .catch(error => console.log('error', error));
  
  return {
    statusCode: 200,
    body: JSON.stringify(ticketData)
  }
}

3. Add the same environment variables to Netlify as well as this new one for the created endpoint:
   `STORYBOOK_MIDDLEWARE_JIRA_ENDPOINT`

   In this case this will be: `/.netlify/functions/get-ticket-data`

Additional configuration

To make tabs for certain subticket statusses persistent and have them show up even if no subticket has that status, you can define status options within .storybook/preview.js as shown below. This array will also define the order in which statusses are shown in the progress bar.

export const parameters = {
  jira: { persistentTabs: [
    'To do', 'In progress', 'Done'
  ] }
}
