Recently, I took over a page of others. The code was messy and jumbled. When I was adding functions, I found that the module I added conflicts with the original module, but I didn't know where the original module was, so I found it.

But I found that this way is too clumsy, and I didn't find the corresponding tool on the Internet, so I wrote a tool myself.

Project address: sdep.

install

npm install sdep -g

Use

sdep [options] <file>

Common command line parameters

• -Q, -- Query < query >: find the dependency chain of a module (for example: - q react)
• -r, --regular: match query as a regular (for example: - Q 'react|react DOM' - R)
• -i, --ignore: do not display files in node \

Third party libraries used

• commander.js
• node-dependency-tree

Example
