<a id="options"></a>
## Options


<a id="include"></a>
### ` include `


Type: ` String | RegExp | Array[...String|RegExp] `  

Default: ` ['**/*.js'] `  

Example: ` include: '**/*.(mjs|js)', `


A pattern, or array of patterns, which specify the files in the build the plugin should operate on.


<a id="exclude"></a>
### ` exclude `


Type: ` String | RegExp | Array[...String|RegExp] `  

Default: ` [] `  

Example: ` exlude: 'tests/**/*', `


A pattern, or array of patterns, which specify the files in the build the plugin should *ignore*.


<a id="debugger"></a>
### ` debugger `


Type: ` Boolean `  

Default: ` true `  

Example: ` debugger: false, `


If ` true ` instructs the plugin to remove debugger statements.


<a id="functions"></a>
### ` functions `


Type: ` Array[...String] `  

Default: ` [ 'console.*', 'assert.*' ] `  

Example: ` functions: [ 'console.log', 'MyClass.Test' ], `


Specifies the functions that the plugin will target and remove.


*Note: specifying functions that are used at the begining of a chain, such as 'a().b().c()', will result in '(void 0).b().c()' which will generate an error at runtime.*


<a id="labels"></a>
### ` labels `


Type: ` Array[...String] `  

Default: ` [] `  

Example: ` labels: ['unittest'], `


Specifies the [labeled blocks or statements](<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/label>) that the plugin will target and remove.


*Note: the '**:**' is implied and should not be specified in the config.*


<a id="sourcemap"></a>
### ` sourceMap `


Type: ` Boolean `  

Default: ` true `  

Example: ` sourceMap: false, `


If ` true `, instructs the plugin to update source maps accordingly after removing configured targets from the bundle.
