Q: Why use Back4app for an Angular CRM app?

Back4app fits Angular CRM: wrap the Parse SDK in an injectable service, expose contacts and deals via signals or observables, and use Live Queries for pipeline updates.

Q: How do I query deals by stage in Angular?

In your service, use new Parse.Query('Deal').equalTo('stage', stage).ascending('expectedCloseDate').find() and push results to a signal or BehaviorSubject.

Q: How do I assign deals to the current user?

Set assignedTo to Parse.User.current() when creating a deal. Query with equalTo('assignedTo', currentUser) to list the user's deals.

Key Takeaways

On this page you get a production-ready CRM schema, a one-click AI prompt, and step-by-step Angular code — so you can ship a CRM app without building the backend.

Deploy in minutes — Paste the AI Agent prompt and get a running app with contacts, companies, deals, and pipeline.
Secure by default — ACLs and role-based access so users see only their assigned deals and data.
Angular-native SDK — Typed objects, async/await, offline pinning, and Live Queries for pipeline updates.
REST + GraphQL — Both APIs auto-generated; filter deals by stage, list activities by relatedTo.
Five classes — _User (built-in), Company, Contact, Deal (pipeline), Activity (tasks/events).

What Is the Angular CRM App Backend Template?

Back4app is a backend-as-a-service (BaaS) ideal for CRM apps: managed database, real-time sync, role-based access, and SDKs for 13+ technologies. The CRM App Backend Template is a pre-built, production-ready backend schema on Back4app. It gives you five classes (_User, Company, Contact, Deal, Activity), pipeline stages, REST and GraphQL APIs, and a one-click AI Agent prompt — so you can connect a Angular frontend and ship a working CRM app in minutes instead of days.

Overview

Angular CRM apps typically use an injectable service to talk to the backend. Back4app's CRM schema is available via the Parse JavaScript SDK; your service calls Parse.Query('Deal').equalTo('stage', stage).find() and exposes results through signals or observables.

The five classes (_User, Company, Contact, Deal, Activity) support pipeline views, contact/company CRUD, and activities. Use Angular guards and interceptors to send the session token; Back4app enforces ACLs so users only see their deals and related data.

Core CRM Features

Angular CRM backend with injectable services and the Parse SDK: contact management, deal pipeline, and activity tracking with signals or observables and ACLs.

Contact management

Store and manage contacts with name, email, phone, company, and notes. Ideal for Angular apps.

Company management

Track companies with name, website, industry, and address. Links to contacts and deals.

Deal pipeline

Sales pipeline with stages, amount, expected close date, and assignment. Built for Angular backends.

Activity tracking

Log calls, emails, meetings, and notes linked to contacts and deals. Works with Angular SDK.

User & permissions

Built-in user model and pointers for ownership and assignment. ACLs out of the box for Angular.

Why Build Your Angular CRM Backend with Back4app?

Back4app gives Angular apps a ready backend so you can focus on services and signals for CRM.

•Injectable service: Wrap the Parse JavaScript SDK in an injectable service; use signals or observables to expose contacts, deals, and pipeline to components.
•Auth and guards: Parse.User session works with Angular guards and interceptors; send the session token in HTTP headers.
•Modern Angular: Fits Angular 18+ with signals and standalone components; same backend for any CRM client.

Ideal for Angular developers building CRM or sales dashboards with injectable services and signals.

Core Benefits

Security & Permissions

How ownership, ACLs, and class-level permissions protect data in this CRM schema.

Row-Level ACLs

Use ACLs and pointers (assignedTo, createdBy) so users only see and edit their assigned deals and related data.

Class-Level Permissions

CLPs restrict which roles or users can create, read, update, or delete objects at the class level.

Pointer-Based Ownership

Deal.assignedTo and Activity.createdBy link to _User; Cloud Code can enforce visibility and edits by role.

Build with AI Agent

Use the Back4app AI Agent to build a real CRM app from this template: it will create the frontend, the backend (this schema, auth, and APIs), and deploy it — no manual setup. The prompt below describes this CRM stack so the Agent can generate a production-ready app in one go.

Back4app AI Agent

Ready to build

Create a CRM app on Back4app with this exact schema and behavior.

Schema:
1. _User (use Back4app built-in): username (String, required), email (String, required), password (String, required); objectId, createdAt, updatedAt (system).
2. Company: name (String, required), website (String), industry (String), address (String), notes (String), createdBy (Pointer to _User); objectId, createdAt, updatedAt (system).
3. Contact: name (String, required), email (String), phone (String), company (Pointer to Company), notes (String), createdBy (Pointer to _User); objectId, createdAt, updatedAt (system).
4. Deal: title (String, required), amount (Number), stage (String; e.g. lead, qualified, proposal, negotiation, won, lost), contact (Pointer to Contact), company (Pointer to Company), expectedCloseDate (Date), notes (String), assignedTo (Pointer to _User); objectId, createdAt, updatedAt (system).
5. Activity: type (String; e.g. call, email, meeting, note), subject (String), description (String), dueDate (Date), completedAt (Date), relatedTo (Pointer to Contact or Deal), createdBy (Pointer to _User); objectId, createdAt, updatedAt (system).

Security:
- Set ACLs so only authenticated users can access data; use role-based or owner-based rules where appropriate (e.g. assignedTo, createdBy).
- Use Class-Level Permissions so only authenticated users can create/read/update/delete these classes.

Auth:
- Sign-up (username, email, password) and login; support logout/session.

Behavior:
- Full CRUD for Company, Contact, Deal, and Activity.
- List deals with filter by stage and order by expectedCloseDate or updatedAt (pipeline view).
- List activities by relatedTo (Contact or Deal).
- Optional: real-time Live Queries for Deal and Activity for dashboard/pipeline updates.
- Optional: offline pinning for mobile (Contacts, Deals, Activities).

Deliver:
- Create the Back4app app with the schema above, ACLs, and any Cloud Code needed.
- Generate the frontend and connect it to this backend; deploy so the app is runnable end-to-end.

Uses the same CRM schema (Contact, Company, Deal, Activity) as this template.

Step-by-Step Angular Integration

Connect to your Back4app backend from a Angular app using the Back4app Angular SDK.

Step 1: Install Back4app Angular SDK
Add the Back4app SDK for your stack (e.g. npm, pubspec, or package manager).
Bash
1
```
npm install parse
```

Step 2: Initialize Back4app in your app

Initialize the Back4app SDK at app startup with your App ID and server URL.

JavaScript

// app.config.ts or main.ts
import Parse from 'parse';

Parse.initialize(
  environment.parseAppId,
  environment.parseJsKey,
  { serverURL: 'https://parseapi.back4app.com' }
);
Parse.serverURL = 'https://parseapi.back4app.com';

Step 3: Query contacts and deals

Use the SDK to fetch Contact and Deal objects; filter deals by stage for the pipeline.

JavaScript

// In CrmService
async getDeals(stage = 'qualified'): Promise<Parse.Object[]> {
  const query = new Parse.Query('Deal');
  query.equalTo('stage', stage);
  query.ascending('expectedCloseDate');
  return await query.find();
}
async getContacts(): Promise<Parse.Object[]> {
  const query = new Parse.Query('Contact');
  return await query.find();
}

Step 4: Create a contact or deal

Create a new Contact or Deal with the required fields and pointers (company, contact, assignedTo), then save.

JavaScript

async createDeal(title: string, stage = 'lead', amount?: number): Promise<Parse.Object> {
  const Deal = Parse.Object.extend('Deal');
  const deal = new Deal();
  deal.set('title', title);
  deal.set('stage', stage);
  if (amount != null) deal.set('amount', amount);
  await deal.save();
  return deal;
}
async createContact(name: string, email?: string, phone?: string): Promise<Parse.Object> {
  const Contact = Parse.Object.extend('Contact');
  const contact = new Contact();
  contact.set('name', name);
  if (email) contact.set('email', email);
  if (phone) contact.set('phone', phone);
  await contact.save();
  return contact;
}

Step 5: Update deal stage and activities

Update Deal.stage when moving in the pipeline; create and list Activity by relatedTo.

JavaScript

async updateDealStage(objectId: string, stage: string) {
  const query = new Parse.Query('Deal');
  const deal = await query.get(objectId);
  deal.set('stage', stage);
  await deal.save();
}
async deleteDeal(objectId: string) {
  const query = new Parse.Query('Deal');
  const deal = await query.get(objectId);
  await deal.destroy();
}

State Management Integration

Integrate the Back4app SDK with your app's state layer (e.g. context, store, or services) for pipeline and contact state.

Full Data Model

Copy a complete CRM model for type-safe serialization (e.g. class, interface, or type definition).

JavaScript

// models/crm.model.ts
export interface Deal {
  objectId?: string;
  title: string;
  amount?: number;
  stage?: string;
  expectedCloseDate?: string;
  contact?: { __type: string; className: string; objectId: string };
  company?: { __type: string; className: string; objectId: string };
  assignedTo?: { __type: string; className: string; objectId: string };
  createdAt?: string;
  updatedAt?: string;
}

export interface Contact {
  objectId?: string;
  name: string;
  email?: string;
  phone?: string;
  company?: { __type: string; className: string; objectId: string };
  notes?: string;
  createdAt?: string;
  updatedAt?: string;
}

export function toDeal(obj: Parse.Object): Deal {
  return {
    objectId: obj.id,
    title: obj.get('title'),
    amount: obj.get('amount'),
    stage: obj.get('stage'),
    expectedCloseDate: obj.get('expectedCloseDate')?.toISOString?.() ?? undefined,
    contact: obj.get('contact'),
    company: obj.get('company'),
    assignedTo: obj.get('assignedTo'),
    createdAt: obj.get('createdAt')?.toISOString?.() ?? undefined,
    updatedAt: obj.get('updatedAt')?.toISOString?.() ?? undefined,
  };
}
export function toContact(obj: Parse.Object): Contact {
  return {
    objectId: obj.id,
    name: obj.get('name'),
    email: obj.get('email'),
    phone: obj.get('phone'),
