Ready to Fly

CI Workflow codecov

Sample app to showcase Slack + Salesforce integrations.

This app has been created using the Salesforce Slack Starter Kit. For a detailed explanation of the app architecture and the scaffolding script, take a look at Salesforce Slack Starter Kit's README.

Prerequisites

To be able to run this project you will need:

Setup Steps

Configuring Slack app at api.slack.com

  1. Open https://api.slack.com/apps/new and choose From an app manifest
  2. Select the workspace you created in the Prerequisites section
  3. Copy the contents of manifest.yml into the text box that says Enter app manifest below and click Next
  4. Review the configuration and click Create
  5. In Basic Information scroll down to the Display Information section. Upload a picture for the app. You can use this logo
  6. Now click Install App on the left menu. Then click the Install to Workspace button and then click on Allow

Deploying the app using a Salesforce Non-scratch org (or a Trailhead Playground) and Heroku

  1. Clone the ready-to-fly repository
git clone https://github.com/trailheadapps/ready-to-fly
  1. Authenticate to your Salesforce org and set as default:
sf org login web --set-default -a mydevorg
  1. Login to your Heroku Account
heroku login
  1. Run Deployment Script
cd ready-to-fly/scripts
npm install
cd ..
node scripts/deploy.js
  1. Choose Non-Scratch Org when the script prompts you to select Salesforce environment

  2. Click Enter to accept the Heroku app name

  3. The script prompts you to enter value for SLACK_BOT_TOKEN. To enter this value open your apps configuration page by first navigating to the apps list and then selecting the app you created in previous section, click OAuth & Permissions in the left hand menu, then copy the value in Bot User OAuth Token and paste into terminal.

Slack Bot Token
  1. The script prompts you for slack signing secret SLACK_SIGNING_SECRET. To enter this value open your apps configuration page by first navigating to the apps list and then selecting the app you created in previous section, click Basic Information and scroll to the section App Credentials and click show button and copy the Signing Secret and paste into terminal.

Deploying the app using a Salesforce scratch org and Heroku

  1. Clone the ready-to-fly repository
git clone https://github.com/trailheadapps/ready-to-fly
  1. Authenticate to your Salesforce org that has DevHub enabled
sf org login web --set-default-dev-hub -a DevHub
  1. Login to your Heroku Account
heroku login
  1. Run Deployment Script
cd ready-to-fly/scripts
npm install
cd ..
node scripts/deploy.js
  1. Choose Scratch Org when the script prompts you to select Salesforce environment

  2. Click Enter to accept the Heroku app name

  3. The script prompts you to enter value for SLACK_BOT_TOKEN. To enter this value open your configuration page by first navigating to the apps list and then selecting the app you created in previous section, click OAuth & Permissions in the left hand menu, then copy the value in Bot User OAuth Token and paste into terminal.

Note: As ready to fly performs calls from Salesforce to Slack, we've modified the Salesforce Slack Starter Kit script to deploy a named credential and a custom metadata type record used for callouts. We've also included the setup of some sample data.

Setting Heroku Instance in your Slack App

This is the final step, you will need to enter the current Heroku Instance url in Slack App.

  1. To enter this value open your apps configuration page from apps list and then selecting the app you created in previous section, click App Manifest. Find the request_url fields (there will be two to update) in the manifest and modify it to replace heroku-app with your actual heroku domain name obtained from step 6 in previous section. Note at the end of this step your url should look like https://<heroku-domain>.herokuapp.com/slack/events.
Signing Secret
  1. Once you have done that, you'll be prompted to verify the events endpoint. Scroll to the top of page and click on 'verify'. You're ready to navigate to the app home!

How to Build and Deploy Code

Building Salesforce app using a Scratch Org

Building Salesforce App Using Non-Scratch Org

Building and deploying Bolt Node.js app

Local Development

  1. To use ngrok, first install it downloading the executable or with npm:
$ npm install ngrok -g
  1. Next you’ll have to sign up.
  2. Once logged in, navigate to “Setup & Installation“ and copy your auth token.
  3. Then set your auth token in your local machine:
$ ngrok authtoken my_auth_token
  1. Run the ngrok tunnel as follows:
$ ngrok http 3000
  1. Copy the ngrok tunnel URL to the following places:
  1. Now you are prepared to run the app locally! In another terminal different from the one in which you’re running ngrok, execute node app.js from the project folder. You can then make changes to the code and restart the app as many times as you want.

Note about Managers DropDown Input

The Managers dropdown that appears when you create a travel request is populated with information pulled from Salesforce. Concretely, we look at the standard Manager field on the User object and pull two levels of Managers in the hirerachy. You can change that behavior to adapt it to your needs.
