What's the difference between path.resolve and path.join?

Question

Is there some difference between the following invocations?

path.join(__dirname, \'app\')

vs.

path.resolve(__dirname, \'app         


        

Answer 1

1) path.resolve creates the absolute path.

The method creates absoulte path from right to left until an absolute path is constructed.

For example:

path.resolve('/a', 'b', 'c');     //    C:\a\b\c
path.resolve('/a', '/b', 'c');    //    C:\b\c
path.resolve('/a', '/b', '/c');   //    C:\c

If absolute path is not generated, the method using current working directory:

For example:

path.resolve('a', 'b', 'c');     //    C:\{current_working_directory}\a\b\c

2) path.join joins all path and the normalize the result

For example:

path.join('/a', '/b', '/c');   //   \a\b\c
path.join('/a', '/b', 'c');    //   \a\b\c
path.join('/a', 'b', 'c');     //   \a\b\c
path.join('a', 'b', 'c');      //   \a\b\c
