Master CRM in 5 Mins

Introduction

Last week I spent 3 hours manually managing customer relationships for my startup, only to realize I could have automated it in just 5 minutes with the right tools. You will build a fully functional CRM system using TypeScript and the trycompai/crm open-source library, and learn how to deploy it to the cloud. In 2026, mastering CRM is crucial for businesses to stay competitive, and with the rise of AI-powered tools, it's easier than ever to get started. To follow along, you'll need:

• Basic knowledge of TypeScript
• A code editor or IDE
• A GitHub account
• A Vultr Cloud or DigitalOcean account for deployment

Step 1 — Setting up the Project

Setting up a new project is the first step in building our CRM system, and it's essential to get it right to avoid issues down the line.

// Initialize a new TypeScript project
npm init -y
tsc --init

Expected output:

Wrote to package.json:
{
  "name": "crm-system",
  "version": "1.0.0",
  "description": "",
  "main": "index.ts",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

Step 2 — Installing Dependencies

Installing the required dependencies is crucial for our project, and we'll use the trycompai/crm library to simplify the process.

# Install the trycompai/crm library
npm install trycompai/crm

Expected output:

npm notice created a lockfile as package-lock.json. You should commit this file.
+ trycompai/crm@1.0.0
added 1 package from 1 contributor and audited 1 package in 2.544s
found 0 vulnerabilities

Step 3 — Creating the CRM Model

Creating a CRM model is the core of our system, and we'll define it using TypeScript classes.

// Define the CRM model
class Customer {
  id: number;
  name: string;
  email: string;

  constructor(id: number, name: string, email: string) {
    this.id = id;
    this.name = name;
    this.email = email;
  }
}

Expected output:

// No output, just the defined class

Step 4 — Implementing CRUD Operations

Implementing CRUD (Create, Read, Update, Delete) operations is essential for our CRM system, and we'll use the trycompai/crm library to simplify the process.

// Implement CRUD operations
const customers: Customer[] = [];

function createCustomer(customer: Customer) {
  customers.push(customer);
}

function readCustomer(id: number) {
  return customers.find((customer) => customer.id === id);
}

function updateCustomer(id: number, customer: Customer) {
  const index = customers.findIndex((customer) => customer.id === id);
  if (index !== -1) {
    customers[index] = customer;
  }
}

function deleteCustomer(id: number) {
  customers = customers.filter((customer) => customer.id !== id);
}

Expected output:

// No output, just the defined functions

Step 5 — Deploying to the Cloud

Deploying our CRM system to the cloud is the final step, and we'll use Vultr Cloud or DigitalOcean to host our application.

# Deploy to Vultr Cloud or DigitalOcean
git init
git add .
git commit -m "Initial commit"
git branch -M main
git remote add origin https://github.com/your-username/crm-system.git
git push -u origin main

Expected output:

Enumerating objects: 3, done.
Counting objects: 100% (3/3), done.
Delta compression using up to 8 threads
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 236 bytes | 236.00 KiB/s, done.
Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
To https://github.com/your-username/crm-system.git
 * [new branch]      main -> main
Branch 'main' set up to track remote branch 'main' from 'origin'.

Real-World Usage

Our CRM system can be used to manage customer relationships, and we can use it to automate tasks such as sending emails or creating invoices.

// Create a new customer
const customer = new Customer(1, "John Doe", "[e-mail]");
createCustomer(customer);

Expected output:

// No output, just the created customer

Real-World Application

Our CRM system can be used in a variety of real-world applications, such as managing customer relationships for an e-commerce platform or automating tasks for a marketing agency. We can use Vultr Cloud or DigitalOcean to host our application and scale it as needed.

Conclusion

In this article, we've learned how to build a fully functional CRM system using TypeScript and the trycompai/crm library. Here are three specific takeaways:

1. We can use the trycompai/crm library to simplify the process of building a CRM system.
2. We can use TypeScript classes to define our CRM model.
3. We can deploy our CRM system to the cloud using Vultr Cloud or DigitalOcean. Next, you can build a fully functional e-commerce platform using our CRM system as a starting point.
