Fundamental Concepts of HubSpot TypeScript#

What is TypeScript in the Context of HubSpot?#

In HubSpot, TypeScript can be used to develop custom code for various features such as custom actions, workflows, and custom objects. The static typing provided by TypeScript helps catch errors early in the development process. For example, if you are working on a custom action that interacts with HubSpot's API to retrieve contact data, TypeScript can ensure that the data you expect to receive from the API matches the types you define in your code.

Type Definitions for HubSpot APIs#

HubSpot provides type definitions for its APIs, which are essential when using TypeScript. These type definitions allow you to have autocompletion and type checking when working with HubSpot's API endpoints. For instance, if you want to use the Contacts API to create a new contact, the type definitions will help you understand the structure of the data you need to send.

// Example of using type definitions for creating a contact
import { ContactsApi, ContactInput } from '@hubspot/api-client/lib/codegen/crm/contacts';
 
const contactsApi = new ContactsApi();
const contact: ContactInput = {
  properties: {
    email: '[email protected]',
    firstname: 'John',
    lastname: 'Doe'
  }
};
 
contactsApi.create(contact).then((response) => {
  console.log(response);
});

Usage Methods#

Setting Up a TypeScript Project in HubSpot#

1. Install Dependencies: First, you need to install the necessary packages. You will need the @hubspot/api - client package to interact with HubSpot's APIs and typescript for TypeScript support.

npm install @hubspot/api-client typescript

2. Configure TypeScript: Create a tsconfig.json file in the root of your project. Here is a basic configuration:

{
  "compilerOptions": {
    "target": "ES6",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true
  }
}

3. Write TypeScript Code: You can now write your TypeScript code in .ts files. For example, you can create a file named main.ts to interact with HubSpot's API.

Interacting with HubSpot APIs#

Once your project is set up, you can start using the HubSpot APIs. Here is an example of retrieving a list of contacts:

import { ContactsApi } from '@hubspot/api-client/lib/codegen/crm/contacts';
import { ApiClient } from '@hubspot/api-client';
 
const apiClient = new ApiClient({
  accessToken: 'YOUR_ACCESS_TOKEN'
});
 
const contactsApi = new ContactsApi(apiClient);
 
contactsApi.getAll().then((response) => {
  console.log(response.body.results);
});

Common Practices#

Error Handling#

When working with HubSpot APIs in TypeScript, it is important to handle errors properly. The HubSpot API client throws errors when something goes wrong. You can catch these errors and handle them gracefully.

import { ContactsApi } from '@hubspot/api-client/lib/codegen/crm/contacts';
import { ApiClient } from '@hubspot/api-client';
 
const apiClient = new ApiClient({
  accessToken: 'YOUR_ACCESS_TOKEN'
});
 
const contactsApi = new ContactsApi(apiClient);
 
contactsApi.getAll().then((response) => {
  console.log(response.body.results);
}).catch((error) => {
  console.error('Error retrieving contacts:', error);
});

Using Enums#

HubSpot's API often uses enums for certain values. For example, when working with contact properties, some properties may have a predefined set of values. You can use TypeScript enums to make your code more readable and less error - prone.

enum ContactStatus {
  Active = 'active',
  Inactive = 'inactive'
}
 
const contact: ContactInput = {
  properties: {
    email: '[email protected]',
    status: ContactStatus.Active
  }
};

Best Practices#

Code Organization#

• Modularize Your Code: Break your code into smaller, reusable modules. For example, you can create a module for handling contact - related operations and another module for dealing with deals.
• Use Interfaces: Define interfaces for complex data structures. This makes your code more self - documenting and easier to understand.

interface ContactInfo {
  email: string;
  firstname: string;
  lastname: string;
}
 
function createContact(contact: ContactInfo) {
  // Code to create contact
}

Testing#

• Unit Testing: Write unit tests for your functions using a testing framework like Jest. This helps ensure that your code works as expected and catches bugs early.

// Function to test
function add(a: number, b: number): number {
  return a + b;
}
 
// Jest test
test('add function should add two numbers correctly', () => {
  expect(add(2, 3)).toBe(5);
});

Conclusion#

Using TypeScript in the HubSpot ecosystem can greatly improve the quality and maintainability of your code. By understanding the fundamental concepts, usage methods, common practices, and best practices, you can develop more robust and error - free applications that interact with HubSpot's APIs. Whether you are building custom actions, workflows, or integrating with other systems, TypeScript provides the tools you need to succeed.
