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 🙏

This is a simple masked text (normal text and input text) component for React-Native.

Supported Versions

React-native: 0.32.0 or higher

Install

npm install @platformbuilders/react-native-masked-text --save

yarn @platformbuilders/react-native-masked-text

Usage (TextInputMask)

For all the masks you will use in this way:

import { TextInputMask } from 'react-native-masked-text'

//...

<TextInputMask
  type={'type-of-the-mask'}
  options={
    {
      // the options for your mask if needed
    }
  }

  // dont forget to set the "value" and "onChangeText" props
  value={this.state.text}
  onChangeText={text => {
    this.setState({
      text: text
    })
  }}
/>

Cel Phone

Mask:

  • BRL (default): (99) 9999-9999 or (99) 99999-9999 (will detect automatically)
  • INTERNATIONAL: +999 999 999 999

If you need a different formatting, use the Custom mask =).

<TextInputMask
  type={'cel-phone'}
  options={{
    maskType: 'BRL',
    withDDD: true,
    dddMask: '(99) '
  }}
  value={this.state.international}
  onChangeText={text => {
    this.setState({
      international: text
    })
  }}
/>

Options

| name | type | required | default | description | | ---------- | ------- | -------- | ------- | ----------- | | maskType | string | no | maskType | the type of the mask to use. Available: BRL or INTERNATIONAL | | withDDD | boolean | no | true | if the mask type is BRL, include the DDD | | dddMask | string | no | (99) | if the mask type is BRL, the DDD mask |

Methods

You can get the unmasked value using the getRawValue method:

<TextInputMask
  type={'cel-phone'}
  options={{
    maskType: 'BRL',
    withDDD: true,
    dddMask: '(99) '
  }}
  value={this.state.international}
  onChangeText={text => {
    this.setState({
      international: text
    })
  }}
  // add the ref to a local var
  ref={(ref) => this.phoneField = ref}
/>

//...

const unmasked = this.phoneField.getRawValue()
// in the mask: (51) 98765-4321
// unmasked: 51987654321

CPF

Mask: 999.999.999-99

<TextInputMask
  type={'cpf'}
  value={this.state.cpf}
  onChangeText={text => {
    this.setState({
      cpf: text
    })
  }}
/>

Methods

You can check if the cpf is valid by calling the isValid() method:

<TextInputMask
  type={'cpf'}
  value={this.state.cpf}
  onChangeText={text => {
    this.setState({
      cpf: text
    })
  }}
  // add the ref to a local var
  ref={(ref) => this.cpfField = ref}
/>

// get the validation

const cpfIsValid = this.cpfField.isValid()
console.log(cpfIsValid) // boolean

You can get the unmasked cpf calling the getRawValue method:

const unmasked = this.cpfField.getRawValue()
// in the mask: 123.456.789-01
// unmasked: 12345678901

CNPJ

Mask: 99.999.999/9999-99

<TextInputMask
  type={'cnpj'}
  value={this.state.cnpj}
  onChangeText={text => {
    this.setState({
      cnpj: text
    })
  }}
/>

Methods

You can check if the cnpj is valid by calling the isValid() method:

<TextInputMask
  type={'cnpj'}
  value={this.state.cnpj}
  onChangeText={text => {
    this.setState({
      cnpj: text
    })
  }}
  // add the ref to a local var
  ref={(ref) => this.cnpjField = ref}

  }}
  // add the ref to a local var
  ref={(ref) => this.datetimeField = ref}
/>

// get the validation

console.log(isValid) // boolean

You can get the moment object from the date if it's valid calling the getRawValue method:

const momentDate = this.datetimeField.getRawValue()

<TextInputMask
  type={'money'}
  value={this.state.simple}
  onChangeText={text => {
    this.setState({
      simple: text
    })
  }}
  // add the ref to a local var
  ref={(ref) => this.moneyField = ref}
/>

const numberValue = this.moneyField.getRawValue()
console.log(numberValue) // Number

// CAUTION: the javascript do not support giant numbers.
// so, if you have a big number in this mask, you could have problems with the value...

Only Numbers

Mask: accept only numbers

Sample code (source):

<TextInputMask
  type={'only-numbers'}
  value={this.state.value}
  onChangeText={text => {
    this.setState({
      value: text
    })
  }}
/>

Zip Code

Mask: 99999-999

Sample code (source):

<TextInputMask
  type={'zip-code'}
  value={this.state.value}
  onChangeText={text => {
    this.setState({
      value: text
    })
  }}
/>

Methods

You can get the unmasked value using the getRawValue method:

<TextInputMask
  type={'zip-code'}
  value={this.state.value}
  onChangeText={text => {
    this.setState({
      value: text
    })
  }}
  // add the ref to a local var
  ref={(ref) => this.zipCodeField = ref}
/>

//...

const unmasked = this.zipCodeField.getRawValue()
// in the mask: 98765-321
// unmasked: 98765321

... Utils

Including the rawText in onChangeText [1.12.0+]

If you need the raw value in every text change, you can use the includeRawValueInChangeText.

It will provide the masked and the raw text in every text change.

<TextInputMask
  type={'cpf'}
  value={this.state.value}
  includeRawValueInChangeText={true}
  onChangeText={(maskedText, rawText) => {
    // maskedText: 123.456.789-01
    // rawText: 12345678901
  }}
/>

Getting the TextInput instance

If you want to get the TextInput raw component, use the getElement() method:

<TextInputMask
  type={'zip-code'}
  value={this.state.value}
  onChangeText={text => {
    this.setState({
      value: text
    })
  }}
  // add the ref to a local var
  ref={(ref) => this.zipCodeField = ref}
/>

//...

const textInput = this.zipCodeField.getElement()

Blocking user to add character

If you want, you can block a value to be added to the text using the checkText prop:

<TextInputMask
  //...
  /**
   * @param {String} previous the previous text in the masked field.
   * @param {String} next the next text that will be setted to field.
   * @return {Boolean} return true if must accept the value.
  */
  checkText={
    (previous, next) => {
      return next === 'your valid value or other boolean condition';
    }
  }
/>

Using custom text inputs

You can use this prop if you want custom text input instead native TextInput component:

const Textfield = MKTextField.textfield()
  .withPlaceholder('Text...')
  .withStyle(styles.textfield)
  .build();


<TextInputMask
  // ...

  // the custom text input component
  customTextInput={Textfield}

  // the props to be passed to the custom text input
  customTextInputProps={{
    style:{ width: '80%' },
    label:'Birthday'
  }}
/>

About the normal text input props

You can use all the normal TextInput props from React-Native, with this in mind:

  • onChangeText is intercepted by component.
  • value is intercepted by component.
  • if you pass keyboardType, it will override the keyboardType of masked component.

Usage (TextMask)

import React, { Component } from 'react'

// import the component
import { TextMask } from 'react-native-masked-text'

export default class MyComponent extends Component {
    constructor(props) {
        super(props)
        this.state = {
            text: '4567123409871234'
        }
    }

    render() {
        // the type is required but options is required only for some specific types.
        // the sample below will output 4567 **** **** 1234
        return (
            <TextMask
                value={this.state.text}
                type={'credit-card'}
                options={{
                    obfuscated: true
                }}
            />
        )
    }
}

Props

The same of TextInputMask, but for React-Native Text component instead TextInput. Warning: if the value not match the mask, it will not appear.

Methods

getElement(): return the instance of Text component.

Extra (MaskService)

If you want, we expose the MaskService. You can use it:

Methods

  • static toMask(type, value, settings): mask a value.
    • type (String, required): the type of the mask (cpf, datetime, etc...)
    • value (String, required): the value to be masked
    • settings (Object, optional): if the mask type accepts options, pass it in the settings parameter
  • static toRawValue(type, maskedValue, settings): get the raw value of a masked value.
    • type (String, required): the type of the mask (cpf, datetime, etc...)
    • maskedValue (String, required): the masked value to be converted in raw value
    • settings (Object, optional): if the mask type accepts options, pass it in the settings parameter
  • static isValid(type, value, settings): validate if the mask and the value match.
    • type (String, required): the type of the mask (cpf, datetime, etc...)
    • value (String, required): the value to be masked
    • settings (Object, optional): if the mask type accepts options, pass it in the settings parameter
  • static getMask(type, value, settings): get the mask used to mask the value

Ex:

import { MaskService } from 'react-native-masked-text'

var money = MaskService.toMask('money', '123', {
    unit: 'US$',
    separator: '.',
    delimiter: ','
})

// money -> US$ 1.23
