  1 | # create-react-static-atlassian-connect-addon
  2 | 
  3 | A boilerplate for static Jira / Confluence [Atlassian Connect addons](https://developer.atlassian.com/static/connect/docs/latest/index.html) built on top of [create-react-app](https://github.com/facebookincubator/create-react-app).
  4 | 
  5 | # Quick Start
  6 | 
  7 | Create Atlassian Connect addon just in a few minutes.
  8 | 
  9 | ![Create Atlassian Connect addon](readme_assets/jira-addon.gif)
 10 | 
 11 | ## Get Development Jira Version
 12 | 
 13 | Follow instruction on the [developer.atlassian.com](https://developer.atlassian.com/static/connect/docs/latest/guides/development-setup.html#cloud-dev)
 14 | 
 15 | ## Setup Addon Project
 16 | 
 17 | ```shell
 18 | git clone https://github.com/leanconvert/create-react-static-atlassian-connect-addon.git <YOUR-ADDON-NAME>
 19 | cd <YOUR-ADDON-NAME>
 20 | rm -rf .git
 21 | npm i
 22 | ```
 23 | 
 24 | **You’ll need to have Node >= 6 on your machine.**
 25 | 
 26 | ## Configure
 27 | 
 28 | ### package.json
 29 | 
 30 | Specify the following properties:
 31 | 
 32 | + `atlassian-connect-dev-instance-host` - name of the host of your Atlassian **development** instance (e.g. `<YOUR-DEV-INSTANCE-NAME>.atlassian.net`)
 33 | + `atlassian-connect-prod-instance-host` - name of the host of your atlassian **production** instance (e.g. `<YOUR-PROD-INSTANCE-NAME>.atlassian.net`)
 34 | + `atlassian-connect-addon-home` - URL to your addon on production (e.g. `<YOUR-ADDON-NAME>.firebaseapp.com`)
 35 | 
 36 | ### atlassian-connect.json
 37 | 
 38 | `atlassian-addon.json` is an Atlassian Addon Descriptor - visit [official Atlassian documentation](https://developer.atlassian.com/static/connect/docs/latest/modules/) for more info.
 39 | 
 40 | ## Start Development
 41 | 
 42 | ```shell
 43 | npm start
 44 | ```
 45 | 
 46 | ## Upload Addon (Jira / Confluence)
 47 | 
 48 | + Go to `https://<YOUR-DEV-INSTANCE-NAME>.atlassian.net/plugins/servlet/upm`
 49 | + Click "Upload add-on"
 50 | + Paste the URL that was automatically added to your clipboard after running `npm start` (path to the `atlassian-connect.json` generated by [ngrok](https://ngrok.com/))
 51 | 
 52 | Now you are all set! Use all the benefits of the `react-create-app` tooling developing an awesome Atlassian add-on.
 53 | 
 54 | ## Atlassian Specific Files
 55 | 
 56 | ### atlassian-addon.json
 57 | 
 58 | `atlassian-addon.json` is an Atlassian Addon Descriptor - visit [official Atlassian documentation](https://developer.atlassian.com/static/connect/docs/latest/modules/) for more info.
 59 | 
 60 | ### scripts/pre-start.js
 61 | 
 62 | + Being executed before `react-scripts start` (see `package.json`)
 63 | + Adds `REACT_APP_HOST` environment variable with your Atlassian development instance host URL specified in the `"atlassian-connect-dev-instance-host"` in your `package.json` file
 64 | + Initializes [ngrok](https://ngrok.com/) to tunnel the `https://localhost:3000`
 65 | + Updates `public/atlassian-connect.json`'s `"baseUrl"` with the by ngrok generated URL
 66 | + Updates `public/atlassian-connect.json`'s `"links/config"` with the full public path to the `atlassian-connect.json` file (e.g. `https:/4c413a45.ngrok.io/atlassian-connect.json`)
 67 | + Adds atlassian-connect public URL (generated by `ngrok`) to the clipboard so you don't need to open the file to copy it yourself before installing in your Atlassian instance
 68 | 
 69 | ### scripts/pre-build.js
 70 | 
 71 | + Being executed before `react-scripts start` (see `package.json`)
 72 | + Adds `REACT_APP_HOST` environment variable with your Atlassian production instance host URL specified in the `atlassian-connect-prod-instance-host` in your `package.json` file
 73 | + Updates `public/atlassian-connect.json`'s `"baseUrl"` with one specified in `package.json`'s `"atlassian-connect-addon-home"` property
 74 | + Updates `public/atlassian-connect.json`'s `"links/config"` with the full public path to the production `atlassian-connect.json` file (e.g. `https://myaddon.firebaseapp.com/atlassian-connect.json`)
 75 | + Adds atlassian-connect **production** public URL to the clipboard so you don't need to open the file to copy it yourself before installing in your Atlassian instance
 76 | 
 77 | ### util.js
 78 | 
 79 | Contains helper functions to be used in `pre-start.js` and `pre-build.js` scripts.
 80 | 
 81 | ## Atlassian Specific Tweaks
 82 | 
 83 | ### package.json
 84 | 
 85 | #### Atlassian specific properties, modules and scripts
 86 | 
 87 | + `atlassian-connect-dev-instance-host` - host URL of your Atlassian development instance
 88 | + `atlassian-connect-prod-instance-host` - host URL of your Atlassian production instance
 89 | + `atlassian-connect-addon-home` - where your addon will be hosted on production
 90 | + `"copy-paste"` - used to add the development `atlassian-connect.json` URL to the clipboard
 91 | + `"ngrok"` - used to create a tunnel to the localhost for the development
 92 | + `"start": "node scripts/pre-start.js & react-scripts start"` - runs `pre-start.js` in addition to `react-scripts start`
 93 | + `"build": "node scripts/pre-build.js & react-scripts build"` - runs `pre-build.js` in addition to `react-scripts build`
