Unable to include fs.js (node externs) in my code. I am using google closure compiler along with node.js -

i want use fs.js in application. trying include line in application, google closure compiler throws error:

var fs = require('fs'); pa057887mac:project_test khuranar$ grunt build  running "exec:closure_dependencies" (exec) task  running "closure-compiler:build" (closure-compiler) task >> grunt-google-closure-compiler: /src/main.js:7: error - failed load module "fs" >>  var fs = require('fs'); >>           ^ >>  >> 1 error(s), 0 warning(s) warning: compilation error use --force continue.  aborted due warnings. 

i know related combination of closure compiler nodejs.

fyi - if use command line check whether application reading file or not, does. persoanlly think, there should changes done gruntfile, not sure. it'll great if help.

i new google closure compiler.

thanks, ritika
