正则表达式帮助匹配以某些文件扩展名结尾的给定单词后的所有内容

Question

I want to be able to match every string which contains "assets" and has a given extension ending - lets say png, jpeg, json.

Those are the cases I could think of and currently, the regex I was able to come with is handling only the first three.

Those are the strings I test against -

./assets/example.js
./assets/recursive-directory/example/exampleTwo.json
../assets/recursive-directory/example/exampleThree.json
../../../assets/recursive-directory/example/exampleThree.json
C:\Users\user1\project\assets\game-assets\translates.json

And here is my current regex -

\.*\/assets\/.*\.(png|jpe?g|gif|json|js)$

Answer 1

If you want to match either slashes or backslashes, you need to say so.

[\\/]assets[\\/].*\.(png|jpe?g|gif|js(on)?)$

The leading \.* wasn't contributing anything useful, so I took it out.

In Javascript, you'll need to backslash-escape the literal backslash, even in a character class.
