I am creating a node command line interface. It is installed globally and uses a bin file to execute.
I plan to have a command window open at the root directory of the files I am working on and then just run the command however I have been unable to determine the current working directory as process.cwd()
is returning the directory of the node package. I initially assumed that since the code is being executed using a batch file as a wrapper (that is how bin files can execute without node at the beginning) then it is impossible but coffee-script manages to do it. I took a look at the coffee-script source but couldn't follow it (not experienced enough).
To test it for yourself create a package with this package.json file:
{
"name": "test-package",
"version": "1.0.0",
"bin": {
"test-package": "./bin/test-package"
},
"main": "/lib/test"
}
this test-package file in bin:
#!/usr/bin/env node
var path = require('path');
var fs = require('fs');
var lib = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');
require(lib + '/test');
Could anyone shed some light onto this.
and then try and get the command line directory inside lib/test.
process.cwd()
returns directory where command has been executed (not directory of the node package) if it's has not been changed by 'process.chdir' inside of application.__filename
returns absolute path to file where it is placed.__dirname
returns absolute path to directory of __filename
.If you need to load files from your module directory you need to use relative paths.
require('../lib/test');
instead of
var lib = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');
require(lib + '/test');
It's always relative to file where it called from and don't depend on current work dir.
