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[]

['log', 'debug', 'info', 'warn', 'error']

Console methods to filter.

console

Type:
