### You can see the full [documentation](https://jsdaddy.github.io/ngx-mask-page/) with examples

## Installing

```bash
$ npm install --save ngx-mask
```

## Quickstart

Import **ngx-mask** module in Angular app.

### With default mask config options

```typescript
import { NgxMaskModule, IConfig } from 'ngx-mask'

export const options: Partial<IConfig> | (() => Partial<IConfig>);

@NgModule({
  imports: [
    NgxMaskModule.forRoot(),
  ],
})
```

### Passing in your own mask config options

```typescript
import { NgxMaskModule, IConfig } from 'ngx-mask'

const maskConfig: Partial<IConfig> = {
  validation: false,
};

@NgModule({
  imports: [
    NgxMaskModule.forRoot(maskConfig),
  ],
})
```

Or using a function to get the config:

```typescript
const maskConfigFunction: () => Partial<IConfig> = () => {
  return {
    validation: false,
  };
};

@NgModule({
  imports: [
    NgxMaskModule.forRoot(maskConfigFunction),
  ],
})
```

Then, just define masks in inputs.

### Usage

```html
<input type="text" mask="<here goes your mask>" />
```

or

```html
<input type="text" [mask]="<here goes a reference to your component's mask property>" />
```

Also, you can use mask pipe.

### Usage

```html
<span>{{phone | mask: '(000) 000-0000'}}</span>
```

For separator you can add thousandSeparator

### Usage

```html
<span>{{value | mask: 'separator':','}}</span>
```

#### Examples

| mask           | example        |
| -------------- | -------------- |
| 9999-99-99     | 2017-04-15     |
| 0\*.00         | 2017.22        |
| 000.000.000-99 | 048.457.987-98 |
| AAAA           | 0F6g           |
| SSSS           | asDF           |

## Mask Options

You can define your custom options for all directives (as object in the mask module) or for each (as attributes for directive). If you override this parameter, you have to provide all the special characters (default one are not included).

### specialCharacters (string[ ])

We have next default characters:

| character |
| --------- |
| -         |
| /         |
| (         |
| )         |
| .         |
| :         |
| **space** |
| +         |
| ,         |
| @         |
| [         |
| ]         |
| "         |
| '         |

#### Usage

```html
<input type="text" [specialCharacters]="[ '[' ,']' , '\\' ]" mask="[00]\[000]" />
```

##### Then

```text
Input value: 789-874.98
Masked value: [78]\[987]
```

```typescript
patterns ({ [character: string]: { pattern: RegExp, optional?: boolean})
```

We have next default patterns:

| code  | meaning                                     |
| ----- | ------------------------------------------- |
| **0** | digits (like 0 to 9 numbers)                |
| **9** | digits (like 0 to 9 numbers), but optional  |
| **A** | letters (uppercase or lowercase) and digits |
| **S** | only letters (uppercase or lowercase)       |

##### Usage

```html
<input type="text" [patterns]="customPatterns" mask="(000-000)" />
```

and in your component

```typescript

```text
Input value: 789HelloWorld
Masked value: (Hel-loW)
```

### Custom pattern for this

```html
<span>{{phone | mask: customMask}}</span>
```

and in your component

```typescript
customMask: [string, pattern];

pattern = {
  P: {

### Repeat mask

You can pass into mask pattern with brackets.

#### Usage

### Thousand separator

You can divide your input by thousands, by default will seperate with a space.

#### Usage

```html
<input type="text" mask="separator" />
```

For separate input with dots.

```html
<input type="text" mask="separator" thousandSeparator="." />
```

For using decimals enter `.` and how many decimals to the end of your input to `separator` mask.

```html
<input type="text" mask="separator.2" />
```

```text
Input value: 1234.56
Masked value: 1 234.56

Input value: 1234,56
Masked value: 1.234,56

Input value: 1234.56
Masked value: 1,234.56
```

```html
<input type="text" mask="separator.2" thousandSeparator="." />
<input type="text" mask="separator.2" thousandSeparator="," />
<input type="text" mask="separator.0" thousandSeparator="." />
<input type="text" mask="separator.0" thousandSeparator="," />
```

For limiting decimal precision add `.` and the precision you want to limit too on the input. **2** is useful for currency. **0** will prevent decimals completely.

```text
Input value: 1234,56
Masked value: 1.234,56

Input value: 1234.56
Masked value: 1,234.56

Input value: 1234,56
Masked value: 1.234

Input value: 1234.56
Masked value: 1,234
```

```html
<input type="text" mask="separator.2" separatorLimit="1000" />
```

For limiting the number of digits before the decimal point you can set `separatorLimit` value to _10_, _100_, _1000_ etc.

```text
Input value: 12345678,56
Masked value: 1.234,56
```
