Webstorm 无法识别 JavaScript 文件

Question

Webstorm doesn't recognize one of my .js files as a JavaScript file so I'm losing syntax highlighting and being able to add break points. I've looked in the workspace.xml file and the file in question seems to have similar settings to other .js files that work correctly.

If I change the name of the file it works ok. So somehow Webstorm is stuck on misinterpreting the type of a file that has this name. Where else can I edit the project?

Answer 1

So I see three possible reasons for the problem:

1. The file was marked as 'Plain text'

2. There is a pattern for 'Text files' file type that matches this file (or back: file type 'JavaScript' exclude this file name). See image below

3. There is a custom plugin that overrides default behavior for files with this name (unlikely)

Updated: after several years I've found one more reason for the behavior and most likely it the main source of the issues. When you create a file without any extensions the " Register New File Type Association " is appeared. And you can accidentally specify a new file type, for some file name. It is can be fixed with (2) but it is the reason why the pattern was added there.

Note: the solution works for all IDEA-based IDEs: IntelliJ IDEA, WebStorm, RubyMine, PyCharm, PhpStorm.

Answer 2

文件 -> 设置 -> 编辑器 -> 文件类型 -> 文本文件 -> 检查那里的“ContentRepository.js”模式并将其删除。

Answer 3

If the file was marked as "Plain Text", then this can be fixed as follows:

1. Right click on the file.

2. One of the menu options is "Mark as Javascript" . Just below "Delete".

3. Click that. Your file is now recognized as javascript by WebStorm.

Since WebStorm was not allowing screenshots after right click so couldn't add it here.

Answer 4

For me this did the trick
1) Preferences
2) Editor
3) FileTypes
4) Search for javascript
5) Add *.js to registered patterns

Answer 5

My problem was with Auto-detect file type by context

Answer 6

You can also try "Template data languages" (in file > settings) which will force a specific language synatax high-lighting on a specific file or folder. See screenshot below

For a block of code you can also use "language injection". Simply high-light the block of code, wait for the little lamp to appear then select the bottom choice and then the language you need (screenshot also attached)

Answer 7

In case it is helpful elsewhere (OMG this was scary).

For some reason IntelliJ was not recognizing any .js file in my project (even after .idea removal ( rm -rf .idea )).

I went to Webstorm (in my case RubyMine ): Webstorm > Preferences ... > Editor > File Types then went to Recognized Filed Types , picked Javascript (but whatever file type you are missing will do), then added back a Registered Patterns entry of *.js

Of course, press Apply and then Ok .

Wow, scary stuff. but solved my problem, hope it does for someone else.

Answer 8

I was always trying to add . js as a recognised file types, but somehow .js was added to Ignored Files and Folders .

I just removed .js from Ignored Files and Folders and it worked for me.

1. Preferences
2. Editor
3. FileTypes
4. Ignored Files and Folders
5. Remove *.js

2022 update!
