Deals summary sample

This tutorial will help you get up to speed with React based UI extensions in the HubSpot CRM. You’ll install a project containing a CRM card with two components. Then you’ll follow the steps to add one more component to the card.

We recommend installing this sample in a Sandbox account.

Update your CLI and & authenticate your account

Full local environment documentation

Update to latest CLI version by running npm install -g @hubspot/cli@latest.
Run hs init if you haven’t already done so to create a config file for your parent account.
Run hs auth to authenticate your account. Alternatively, select your pre-authenticated account with hs accounts use.

Clone the project and upload it to your HubSpot sandbox account

Run the command hs project upload to upload this sample project to your HubSpot account
In the main menu of your HubSpot account navigate to Contacts > Contacts. Click into the Brian Halligan contact.
Select the Custom tab in the middle pane of this contact record
You should see the Deals summary card with two components: Deals and Unit Price. These will both be set to 0 because there are currently no deals associated with this contact.

Create two deal records

In the main menu, navigate to Sales > Deals.
Click Create deal in the top right hand corner.
Give your dummy deal a name, an amount, and set the deal association to the Brian Halligan contact.
Repeat the last two steps to create a second deal.
In the main menu of your HubSpot account navigate to Contacts > Contacts. Click into the Brian Halligan contact. Now you should see 2 deals listed in the Deals summary card and the sum total of the amounts you entered for each deal. Next you’ll add an Average Margin component.

Setup local dev

Full Local dev documentation | Full Secrets documentation

Run npm install to install dependencies for this project.
Create a file named .env inside the app.functions folder (inside src/app)
In your HubSpot account, click on the CRM development item in the main navigation
In the sidebar under Tools select Private apps and find the Deals summary app. Click View access token and copy this token to your clipboard.
Add it to your .env file

To begin the dev process and automatically see your changes reflected in the CRM, run hs project dev.
Return to the contact record and refresh the browser. You should now see a developing locally icon next to the card title.

Add the Average Margin component

Open the get-data.js file in your local text editor. This file is using the HubSpot API client to fetch deal data related to whichever contact record an end user is viewing in the CRM. This fetching is being done by the getAssociatedDeals function. The result of this function is stored in a deals variable. The calculateTotalAmounts function is using this data to calculate the total amount of deals.
To begin the dev process and automatically see your changes reflected in the CRM, run hs project dev.
Add a function called calculateAverageAmount below the calculateTotalAmounts function. It should look like this:

function calculateAverageAmount(deals) {
  const totalCount = deals.length;

  const amounts = deals.map((deal) => parseFloat(deal.properties.amount));
  const totalDeals = amounts.reduce((sum, amount) => sum + amount, 0);

  const average = Math.ceil(totalDeals / totalCount);
  return -Math.round(-average);
}

Next add a variable in the exports statement at the top of the file to store the result of this function and add this variable to the send response.

const avgAmount = calculateAverageAmount(deals);
sendResponse({ deals, totalAmount, avgAmount });

This is everything required for fetching the data and making it available to the front end. Open the DealsSummary.jsx file to add this data to the CRM card.
First, add a state variable to define the initial state of the average amount

const [avgAmount, setAvgAmount] = useState(0);

Next, update the state within the useEffect function

setAvgAmount(serverlessResponse.response.avgAmount);

Finally, add a new StatisticsItem component to display the average amount in the CRM card

<StatisticsItem label="Avg margin" number={avgAmount}>
  <Text>Low End</Text>
</StatisticsItem>
