please guide me generate .js , .ds through node.js

you have 2 options:

• run tsc.js node script
• use typescript npm module

run node tsc.js

this approach taken tools e.g grunt-ts. call spawn on current process process.execpath passing in other commands args (-d).

one sample

run typescript node module

if playing typescript compiler api highly recommend ntypescript see readme reasons.

the typescript compiler provides simple function called transpile can use expected output , write out disk yourself.
