TypeScript has built-in support for regular expressions through JavaScript’s RegExp object. RegexBuddy makes it very easy to use the RegExp object in your TypeScript source code. When you select TypeScript as your application, RegexBuddy emulates the JavaScript regex flavor just as it is implemented by the latest versions of Chrome, Firefox, and Edge.
First, use RegexBuddy to define a regex or retrieve a regexp saved in a RegexBuddy library. Rely on RegexBuddy’s clear regex analysis, which is constantly updated as you build the pattern, rather than dealing with the cryptic regex syntax on your own. Detailed help on that syntax is always only a click away.
If you copied a regex written for another programming language, simply paste it into RegexBuddy, select the original language, and then convert the regex to TypeScript’s regex flavor. You can also convert from a legacy JavaScript version to the current standards.
If you created a new regular expression, test and debug it in RegexBuddy before using it in your TypeScript source code. Test each regex in RegexBuddy’s safe sandbox without risking precious data. Quickly apply the regex to a wide variety of input and sample data, without having to produce that input through your script.
Finally, let RegexBuddy generate a source code snippet that you can copy and paste directly into your TypeScript code editor. Just choose what you want to use the regex for, and a fully functional code snippet is ready. You can change the names of variables and parameters to suit your naming style or the current situation, which RegexBuddy automatically remembers. RegexBuddy generates proper TypeScript code that declares the types of all variables.
Don’t bother trying to remember TypeScript’s specific regexp syntax. And don’t worry about properly escaping backslashes and other characters. Just tell RegexBuddy what you want to do, and you will get the proper TypeScript code straight away. Anything can be done: testing a string for a match, extracting search matches, validating input, search-and-replace, splitting a string, etc.
