Project Overview and Setup
Configuring Dependencies
lovable.config.json
. This file is used to define and load dependencies for the project.lovable.config.json
to include modules that support database operations and CRM functionalities:
{
"dependencies": {
"lovable-crm-module": "latest",
"lovable-database": ">=1.0.0"
}
}
Creating CRM Data Models
crm\_models.lov
in your project directory. This file will define the data entities for your CRM system.
module CRMModels {
// Define a Contact entity
entity Contact {
id: ID,
firstName: String,
lastName: String,
email: String,
phone: String
}
// Define a Lead entity
entity Lead {
id: ID,
name: String,
email: String,
status: String
}
}
Creating API Endpoints
crm\_api.lov
in your project workspace. This file will contain functions to interact with your data models.crm\_api.lov
to implement basic API endpoints for retrieving and creating contacts:
module CRMApi using CRMModels {
// Endpoint to retrieve all contacts from the database
function getContacts() {
return Database.findAll(CRMModels.Contact);
}
// Endpoint to create a new contact in the database
function createContact(data) {
return Database.insert(CRMModels.Contact, data);
}
}
Building the User Interface
crm\_ui.lov
in your project folder. This file will manage the front-end interface of your CRM.crm\_ui.lov
to build a simple UI that displays contacts and allows adding a new contact:
module CRMUI {
import CRMApi;
// Function to render the contacts page
function renderContactsPage() {
let contacts = CRMApi.getContacts();
// Render the contacts in a table using Lovable's UI module
UI.renderTable(contacts);
}
// Function to render a form to add a new contact
function addContactForm() {
let form = UI.createForm({
fields: ["firstName", "lastName", "email", "phone"]
});
form.onSubmit = (data) => {
CRMApi.createContact(data);
UI.refreshPage();
};
UI.renderForm(form);
}
}
Linking Components and Application Bootstrapping
main.lov
in your workspace. This file serves as the entry point of your CRM system.main.lov
to connect your UI component and start your application:
import CRMUI from "crm\_ui.lov";
function main() {
// Render the contacts page when the application starts
CRMUI.renderContactsPage();
}
main();
Testing and Running Your CRM System
main.lov
which in turn calls the UI functions, displaying contacts and the add contact form.
