javascript - include a module into another nodeJS file -
i getting started node , wrote little s3 reader looks following. sits in projectroot/routes/s3store.js directory.
var aws = require('aws-sdk'), uploader = require('s3-upload-stream')(new aws.s3()), q = require('q'); module.exports = s3store; function s3store(config) { this.config = config; this.s3 = new aws.s3({ region: config.aws.region }); } s3store.prototype.readstream = function (filepath, metadata) { var readconfig = { 'bucket': this.config.s3.bucketname, 'key': filepath }; return this.s3.getobject(readconfig).createreadstream(); } now, created new file s3storemain.js in projectroot/routes/s3storemain.js , trying import s3store.js module this:
var s3 = require('s3store'); on running:
node s3storemain.js it cannot find module s3store. here stacktrace:
shubham@turing:~/downloads/node-v0.12.4/exp2014$ node routes/s3storemain.js module.js:340 throw err; ^ error: cannot find module 's3store' @ function.module._resolvefilename (module.js:338:15) @ function.module._load (module.js:280:25) @ module.require (module.js:364:17) @ require (module.js:380:17) @ object.<anonymous> (/home/shubham/downloads/node-v0.12.4/exp2014/routes/s3storemain.js:1:72) @ module._compile (module.js:456:26) @ object.module._extensions..js (module.js:474:10) @ module.load (module.js:356:32) @ function.module._load (module.js:312:12) @ function.module.runmain (module.js:497:10) shubham@turing:~/downloads/node-v0.12.4/exp2014$ what missing?
in order require modules files relatively need use relative paths... how require module designed with-in nodejs (read api docs linked more information)
try requiring s3store file s3storemain file so:
var s3 = require("./s3store"); you can omit ".js", it's optional.
note saying need put modules.exports @ end of file... false!! due how defined function, referencing shouldn't matter.
