Angular: JSON Powered forms For Angular

Form.io Angular JSON Form Renderer

This library serves as a Dynamic JSON Powered Form rendering library for Angular. This works by providing a JSON schema to a <formio> Angular component, where that form is dynamically rendered within the front end application. This allows forms to be dynamically built using JSON schemas.

Angular Material

If you are looking for Angular Material support, then this is within a separate library @ https://github.com/formio/angular-material-formio

Running Demo

To run a demo of the Form.io Angular renderer, please follow these steps.

  1. Make sure you have the Angular CLI installed on your machine.
  2. Download the Angular Demo Application to your computer.
  3. With your terminal, type npm install
  4. Now type ng serve

This will startup an example application where you can see all the features provided by this module.

Here is the hosted demo application https://formio.github.io/angular-demo/

Using within your application

You can easily render a form within your Angular application by referencing the URL of that form as follows.

<formio src='https://examples.form.io/example'></formio>

You can also pass the JSON form directly to the renderer as follows.

<formio [form]='{
    "title": "My Test Form",
    "components": [
            "type": "textfield",
            "input": true,
            "tableView": true,
            "inputType": "text",
            "inputMask": "",
            "label": "First Name",
            "key": "firstName",
            "placeholder": "Enter your first name",
            "prefix": "",
            "suffix": "",
            "multiple": false,
            "defaultValue": "",
            "protected": false,
            "unique": false,
            "persistent": true,
            "validate": {
                "required": true,
                "minLength": 2,
                "maxLength": 10,
                "pattern": "",
                "custom": "",
                "customPrivate": false
            "conditional": {
                "show": "",
                "when": null,
                "eq": ""
            "type": "textfield",
            "input": true,
            "tableView": true,
            "inputType": "text",
            "inputMask": "",
            "label": "Last Name",
            "key": "lastName",
            "placeholder": "Enter your last name",
            "prefix": "",
            "suffix": "",
            "multiple": false,
            "defaultValue": "",
            "protected": false,
            "unique": false,
            "persistent": true,
            "validate": {
                "required": true,
                "minLength": 2,
                "maxLength": 10,
                "pattern": "",
                "custom": "",
                "customPrivate": false
            "conditional": {
                "show": "",
                "when": null,
                "eq": ""
            "input": true,
            "label": "Submit",
            "tableView": false,
            "key": "submit",
            "size": "md",
            "leftIcon": "",
            "rightIcon": "",
            "block": false,
            "action": "submit",
            "disableOnInvalid": true,
            "theme": "primary",
            "type": "button"

This is a very simple example. This library is capable of building very complex forms which include e-signatures, columns, panels, field conditionals, validation requirements, and the list goes on and on.


To use this library within your project, you will first need to install it as a dependency.

npm install --save @formio/angular formiojs

You can now include the module in your Angular application like so.

import { FormioModule } from '@formio/angular';
    imports: [ BrowserModule, CommonModule, FormioModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
export class AppModule { }

Included Libraries

This library is a combination of multiple libraries that enable rapid Serverless application development using Form.io. These libraries are as follows.

  1. Form Renderer - The form renderer in Angular
  2. Form Builder - The form builder in Angular
  3. Form Manager - The form management application used to manage forms.
  4. Authentication - Allows an easy way to provide Form.io authentication into your application.
  5. Resource - A way to include the Resources within your application with full CRUDI support (Create, Read, Update, Delete, Index)
  6. Data Table (Grid) - A way to render data within a Table format, which includes pagination, sorting, etc.

Full Documentation

To read up on the full documentation of this library, please check out the Wiki Page

About Form.io

Form.io is a combined form and data management API platform created for developers who are building "Serverless" form-based applications. Form.io provides an easy drag-and-drop form builder workflow allowing you to build complex forms for enterprise applications quickly and easily. These forms are then embedded directly into your application with a single line of code that dynamically renders the form (using Angular or React) in your app while at the very same time generating the RESTful API to support those forms. The Form.io platform also offers numerous 3rd-party services that are fully integrated into the form building process allowing you to extend the power and capability of your apps while saving time and effort.

You can use this renderer with Form.io by simply pointing the src parameter to the URL of the form. For example, the following URL points to the JSON schema of a form built on Form.io.


To render this form, you simply provide that URL to the <formio> directive like so.

<formio src="https://pjmfogrfqptslvi.form.io/test"></formio>

Not only will this render the form, but it will also submit that form to the provided API endpoint.

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

  1. Installing Node.js and npm
  2. Installing Angular CLI
  3. Creating workspace
  4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Angular environment setup

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

  • Node.js
  • npm Package Manager

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

  1. npm -v

Installing Angular CLI

  • Open Terminal/Command Prompt
  • To install Angular CLI, run the below command:
  1. npm install -g @angular/cli

installing angular CLI

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

  1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

  • Using CLI
  • Using Visual Studio Code
1. Using CLI

To create a workspace:

  • Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
  • Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:
  1. Ng new YourAppName

create angular workspace

  • After running this command, it will prompt you to select from various options about the CSS and other functionalities.

angular CSS options

  • To leave everything to default, simply press the Enter or the Return key.
