## API

### filterConsole(excludePatterns, options?)

Returns a function, which when called, disables the filter.

#### excludePatterns

Type: `Array`

Console output that matches any of the given patterns are filtered from being logged. The patterns are matched against what would be logged and not the `console` method input arguments directly. Meaning an exclude pattern of `'foo bar'` will match `console.log('foo %s', 'bar')`.

Filter types:

- `string`: Checks if the string pattern is included in the console output.

- `RegExp`: Checks if the RegExp pattern matches the console output.

- `Function`: Receives the console output as a string and is expected to return a truthy/falsy value of whether to exclude it.

#### options

Type: `object`

##### methods

Type: `string[]`\

Default: `['log', 'debug', 'info', 'warn', 'error']`

Console methods to filter.

##### console

Type: `object`\

Default: `console`

Use a custom `console` object. Can be useful for testing or mocking.
