从任何地方在Windows命令中执行单个Node.js文件

Question

I have a Node.js file in c:\\scripts and want to execute them in Windows command from anywhere by node my-file.js . It's kind of requirement for execute a bat file, which I can put the folder in %PATH% . I've tried to include c:\\scripts in %NODE_PATH% but it doesn't work.

Answer 1

nodejs has the notion of executables ... for example package

jslint

once installed can be directly executed from anywhere ... its installed using the -g flag as in :

npm install -g jslint

just like normal packages its code is installed in dir defined by env var

NODE_PATH

additionally its executable lives in the bin dir which is by default added to PATH during initial nodejs install

on linux

type jshint
jshint is /home/stens/node-v5.8.0/bin/jshint


echo $NODE_PATH
/home/stens/node-v5.8.0/lib/node_modules

on windows box similar happens just examine your PATH to see the nodejs bin dir ... on linux its a location relative to $NODE_PATH

UPDATE :

Alternative to above you can put a some-file (do Windows equivalent to chmod +x some-file to make it an executable) into a dir listed in your $PATH ... for example on linux if I issue

type jslint

which is found because PATH contains dir /home/stens/node-v5.8.0/bin ... above command outputs :

jslint is hashed (/home/stens/node-v5.8.0/bin/jslint)

then show contents

cat /home/stens/node-v5.8.0/bin/jslint

#!/usr/bin/env node

var main = require("../lib/main.js");

main.runMain(main.parseArgs());

you can see the executable file in just nodejs code with the 1st line

#!/usr/bin/env node

which tell the system to execute it using node (dunno the Windows way but similar must be available)

so its executed using

jslint blah input-blah parm-blah goes-blah here-blah

Hopefully this tips you in the right direction
