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"
        }
    ]
}'></formio>

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.

Usage

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';
@NgModule({
    imports: [ BrowserModule, CommonModule, FormioModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
export class AppModule { }

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.

https://pjmfogrfqptslvi.form.io/test

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
Node.js

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.

Angular Form Generator & Pitfalls

Ever felt repetitive creating forms in your Angular Application? Let’s fix it.

Intro

During the Front-end development days it feels like there is a lot of repetitive code which I have to write to design my forms which are almost all the time very close one to another.

I’ve been recently looking into ways of automating it. The furthest I wanted to go was to have some kind of interface between a more friendly modelling object as well as to an interface to link my objects to the Angular Modelling Universe.

This way, I discovered there is already a library that could do it for me formly. But looking over their documentation I realized this is a little bit more than I wanted.

As a result, I ended writing my own form generator. You’ll see that except for two or three pitfalls this is rather easy to achieve.

Foreground

I’ll be using Angular Materials to generate my forms.

I have two tips to share about their design. It can be difficult to change the colors or design a theme for them. You’ll see the documentation on their side is rather not the best on this subject. My piece of advice, use  https://materialtheme.arcsine.dev/. In case you don’t know exactly what colors to use but you have a slight idea about it, I recommend using  https://www.cssportal.com/css-color-converter/0000D8. In the end you’ll definitely discover some very cool Angular Material Theme which you can even share with others.

Getting Started

First of all, we’ll organize our application on modules. When it comes to Angular I always split the code in presentation and business. From where I’m standing, presentation means those components that deal with UX functionality, they can work by themselves but they don’t make sense for a user taken alone; business are those components that configure and group together presentation through a context.

Basics of Angular: Part-1

What is Angular? What it does? How we implement it in a project? So, here are some basics of angular to let you learn more about angular.

Angular is a Typescript-based open-source front-end web application platform. The Angular Team at Google and a community of individuals and corporations lead it. Angular lets you extend HTML’s syntax to express your apps’ components clearly. The angular resolves challenges while developing a single page and cross-platform applications. So, here the meaning of the single-page applications in angular is that the index.html file serves the app. And, the index.html file links other files to it.

We build angular applications with basic concepts which are NgModules. It provides a compilation context for components. At the beginning of an angular project, the command-line interface provides a built-in component which is the root component. But, NgModule can add a number of additional components. These can be created through a template or loaded from a router. This is what a compilation context about.

What is a Component in Angular?

Components are key features in Angular. It controls a patch of the screen called a view. A couple of components that we create on our own helps to build a whole application. In the end, the root component or the app component holds our entire application. The component has its business logic that it does to support the view inside the class. The class interacts with the view through an API of properties and methods. All the components added by us in the application are not linked to the index.html. But, they link to the app.component.html through the selectors. A component can be a component and not only a typescript class by adding a decorator @Component. Then, for further access, a class can import it. The decorator contains some metadata like selector, template, and style. Here’s an example of how a component decorator looks like:

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.scss']
})

Role of App Module

Modules are the package of functionalities of our app. It gives Angular the information about which features does my app has and what feature it uses. It is an empty Typescript class, but we transform it by adding a decorator @NgModule. So, we have four properties that we set up on the object pass to @NgModule. The four properties are declarations, imports, providers, and bootstrap. All the built-in new components add up to the declarations array in @NgModule.

@NgModule({
declarations: [
  AppComponent,
],
imports: [
  BrowserModule,
  HttpClientModule,
  AppRoutingModule,
  FormsModule
],
bootstrap: [AppComponent]
})

What is Data Binding?

Data Binding is the communication between the Typescript code of the component and the template. So, we have different kinds of data binding given below:

  • When there is a requirement to output data from our Typescript code in the HTML template. String interpolation handles this purpose like {{data}} in HTML file. Property Binding is also used for this purpose like [property] = “data”.
  • When we want to trigger any event like clicking a button. Event Binding works while we react to user events like (event) = “expression”.
  • When we can react to user events and output something at the same time. Two-way Binding is used like [(ngModel)] = “data”.
