Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Angular Inputs Validation

This library was generated with Angular CLI version 11.0.9.

Client-side Validation should be simple and clean. Don't let Client-side Validation dirty your controller.

Setup your Validation on config phase by using some rules (example) If you prefer schema over html attributes , try AngularInputsValidation (Demo) And add Validation in your view only.

angularjs 11.1.x support to version AngularInputsValidation 0.0.2 angularjs 12.3.x support after version AngularInputsValidation 0.0.2

Requirement

Angular 11.0.9 (for AngularInputsValidation 0.0.2) Angular 12.0.9 (for AngularInputsValidation 0.0.2)

DEMO

Stackblitz link : https://stackblitz.com/edit/angular-11-new-fagk4h?file=src%2Fapp%2Fapp.component.ts

This is Stackblitz link.

Installation

npm i angular-inputs-validations

Using Angular-inputs-validation

1. Import Angular-inputs-validation Service

In the module where you want to use the Angular-inputs-validation, import the Angular-inputs-validation as follows:

import {AngularValidationsService} from "angular-validations-services"

2. Configuration

To configure the validation messages, you need to perform the following steps:

Step 2.1:

import your component:


constructor(public validateService: AngularValidationsService) {  }
Step 2.2: Define Validation Messages

import your component:

import {AngularValidationsService} from "angular-validations-services"

constructor(public validateService: AngularValidationsService) {  }

 this.validateService.confirmPasswordValidators("password123", "password234");

 this.validateService.emailValidation("[email protected]");

 this.validateService.nameFieldCheck("Name");

 this.validateService.passwordValidation("password@123");

 this.validateService.numberValidation(863567272);

There are two ways we can use this. The first way involves sending a function call from an input field in the template HTML to the TypeScript file. At that time, we call this function and pass the value to validate it. Another way is to use this function in the FormGroup validation. Inside the FormGroup, a particular FormControl calls the function and passes the data for validation. If there's any error, the function returns an error object; if there's no error, the function returns null.

way 1

  
 this.validateService.confirmPasswordValidators("password123", "password234");

 this.validateService.emailValidation("[email protected]");

 this.validateService.nameFieldCheck("Name");

 this.validateService.passwordValidation("password@123");

 this.validateService.numberValidation(863567272);

Way 2


 this.signupForm = this.fb.group({
     fullName: ['', [Validators.required,this.validateService.nameFieldCheck(this)]],})

3. Usage in templates

Now, in your component's template, you can use the ValidationMessagesComponent to display the validation messages.

way 1


 <input type="text" placeholder="name" (input)="checkvalidation($event)">

way 2

 <div class="text-danger" *ngIf="form['fullName'].invalid && (form['fullName'].dirty || form['fullName'].touched)">
  <small class="required-field " *ngIf="form['fullName'].errors?.['required']">Name is required.</small></div>

Message

Regex pattern used ^[^\s$&*!#^@]+@[^\s@]+.([^\s@]{2,3})+$ Message key will throw an error if there is an Regex Error in the entered EmailID.

| Propert | Definition |
| :---: | :---: | | nameFieldCheck | This function alidates name fields, ensuring that the first character is not a whitespace and validate special character. (example:nameFieldCheck(value)) |
| emailValidation |This function validates a valid email using regex. (example:emailValidation(value)) | | numberValidation |This function checks a number field for minimum and maximum length. (example:numberValidation(value)) |
| passwordValidation | This function validates strong passwords, ensuring there are no whitespace characters, and checks for both minimum and maximum password lengths. Additionally, it uses regex to verify the strength of the password. (example:passwordValidation(value)) |
| confirmPasswordValidators | This function checks whether the new password and the confirm password values are the same. (example:confirmPasswordValidators(value1,value2)) | | value | The parameter type for this function is now set to 'any' for the value (example:passwordValidation(value)) |
| value1,value2 | Two values are present: value1 represents the new password, and value2 represents the confirm password.(example:confirmPasswordValidators(value1,value2)) |

Regex

| Regex | Definition | | :---: | :---: | |name field | This regex validates the presence of special characters in a name field. (example: /^[A-Za-z' -.]+$/ ) | | email pattern | This regex validates the correct email pattern. (example:/^(([^<>()[]\.,;:\s@"]+(.[^<>()[]\.,;:\s@"]+))|.(".+"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/) | | Specialcharacter| This regex checks for a strong password in password fields.(example:/^(?=[^a-z][a-z])(?=[^A-Z][A-Z])(?=\D\d)(?=[^@$!%#?&][@$!%#?&])[A-Za-z\d@$!%#?&]*$/) |

Code scaffolding

Run ng generate component component-name --project angular-inputs-validation to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module --project angular-inputs-validation.

Note: Don't forget to add --project angular-inputs-validation or else it will be added to the default project in your angular.json file.

Build

Run ng build angular-inputs-validation to build the project. The build artifacts will be stored in the dist/ directory.

Publishing

After building your library with ng build angular-inputs-validation, go to the dist folder cd dist/angular-inputs-validation and run npm publish.

Running unit tests

Run ng test angular-inputs-validation to execute the unit tests via Karma.
