How to Extract Text Enclosed in Curly Braces Using Regular Expressions?

Retrieve Text Between Curly Braces Using Regular Expressions

Despite repeated attempts over the years, regex remains an elusive concept for some developers. To avoid the frustrations of yet another failed regex endeavor, let's seek assistance from the experts at Stack Overflow.

The Problem

The objective is to extract the text enclosed within curly braces from an input string, such as {getThis}. The desired output is "getThis."

The Solution

To accomplish this, we can utilize the following regex:

/{.*?}/

This pattern matches any sequence of characters (represented by .*?) surrounded by curly braces ({ and }). The ? quantifier ensures that it captures the shortest possible matching string, preventing it from being greedy and matching additional text.

Alternatively, the following regex could also solve the problem:

/{([^}]*)}/

This pattern excludes curly braces from the matching, ensuring that only the characters between them are captured.
