Parameters

Name	Description	Mandatory	Default value
method	The method to trap. This could be any function or attribute that is accessible under window. e.g. JSON.stringify, atob...	Yes	n.a.
search	The text or regex pattern to replace	Yes	n.a.
replacement	The replacement text	No	empty string
decodeMethod	The decode method. When provided the snippet can decode the encoded text before replacing it. Useful for functions like btoa. Currently only “base64” is supported.	No	empty string
path	Dot-separated path to the property in returned objects. Can be used to override return values for functions that return objects instead of primitive strings. If left empty, only functions that return strings will be tackled. e.g. user.profile.name.	No	empty string
stack	Comma-separated list of strings to check in the stack trace. If provided the replacement will only apply when the stack trace contains at least one of these patterns.	No	empty string

Filter examples

Filter	Result
replace-outbound-value 'JSON.stringify' '"ads":true' '"ads":false'	window.testData = { user: "john", ads: true }; const res = JSON.stringify(window.testData); res will have ads: false
replace-outbound-value 'testObj.getText' '/first.*second/' ''	window.testObj = { getText: () => "Anything between first" + "and second will be removed." }; console.log(window.testObj.getText()); Should print "Anything between will be removed"
replace-outbound-value 'btoa' 'ads' 'content' 'base64'	const encoded1 = btoa("This text contains ads"); const encoded2 = btoa("This text contains content"); console.log(encoded1 === encoded2); Encoded should have the base64 encoded version of "This text contains content"
replace-outbound-value 'testObj.getData' 'premium' 'basic' '' 'user.profile.name'	window.testObj = { getData: () => ({ user: { profile: { name: "John premium", status: "premium_user" }, settings: { theme: "premium_theme" } }, config: { ads: "premium_ads" } }) }; console.log(window.testObj.getData()) user.profile.name will be John basic. Rest of the premium values should not be changed.
replace-outbound-value 'testObj.getText' 'ads' 'content' '' '' 'callerFunction'	window.testObj = { getText: () => "Contains ads" }; window.callerFunction = function callerFunction() { return window.testObj.getText(); }; window.otherCallerFunction = function otherCallerFunction() { return window.testObj.getText(); }; It should return "Contains content" when callerFunction is called, it should return “Contains ads” when otherCallerFunction is called.
