Hello, I'm developing a file manipulation system, and I just want to be able to manipulate folder with an absolute path eg /opt/file . In other words, I can only create / edit / delete folders on this path. I want to validate that the start path is always / opt / file.

What is the best way to do this? Thanks

javascript node.js

Since the path is a string you can use the indexOf in question starts with the text that was provided. It would look something like this:

...
if (path.indexOf('/opt/file') === 0) {
  // Faz o que deve fazer com o arquivo
...

string

The indexOf method returns the index of the first occurrence of the value specified in searchValue within the indexOf() object to which it was called, starting the search from String . Returns -1 if the value is not found.

Syntax
str.indexOf(searchValue[, fromIndex])
searchValue

A string representing the value to be fetched.

fromIndex

The position of the original string from which the search should begin. It can be any integer. The default value is 0. If fromIndex the entire string is traversed (equivalent to passing 0). If fromIndex < 0 , the method will return -1.
