path-env
Manipulate $PATH
-like environment variable
Requirements
- Node.js ≥ 8.9.0
Usage
NOTE:
- Everything is chainable.
Modifying $PATH
and get its value
import {pathString} from 'path-env'
const path = pathString()
.append(['/append/bin'])
.prepend(['/prepend/bin'])
.surround(['/surround/bin'])
.get.string()
console.log(path)
This will print /surround/bin:/prepend/bin:...:/append/bin:/surround/bin
in POSIX systems.
Modifying a $PATH
-like and get its value
Modifying $NODE_PATH
.
import {pathString} from 'path-env'
const path = pathString('NODE_PATH')
.append(['/append/node_modules'])
.prepend(['/prepend/node_modules'])
.surround(['/surround/node_modules'])
.get.string()
console.log(path)
This will print /surround/node_modules:/prepend/node_modules:...:/append/node_modules:/surround/node_modules
in POSIX systems.
Modifying $PATH
-like property of env
object
You can also modify $PATH
-like value directly from an env
-like object.
Signature:
import {pathEnv} from 'path-env'
const env = pathEnv() // equivalent to `const env = pathEnv(process.env, 'PATH')`
.path.append(['/append/bin'])
.path.prepend(['/prepend/bin'])
.path.surround(['/surround/bin'])
.get.env()
console.log(env)
Result: env
will looks exactly like process.env
except modified PATH
property.
