Node.js, can’t open files. Error: ENOENT, stat ‘./path/to/file’
Paths specified with a . are relative to the current working directory, not relative to the script file. So the file might be found if you run node app.js but not if you run node folder/app.js. The only exception to this is require(‘./file’) and that is only possible because require exists per-module and thus knows … Read more
req.locals vs. res.locals vs. res.data vs. req.data vs. app.locals in Express middleware

require file as string
If it’s for a (few) specific extension(s), you can add your own require.extensions handler: var fs = require(‘fs’); require.extensions[‘.txt’] = function (module, filename) { module.exports = fs.readFileSync(filename, ‘utf8’); }; var words = require(“./words.txt”); console.log(typeof words); // string Otherwise, you can mix fs.readFile with require.resolve: var fs = require(‘fs’); function readModuleFile(path, callback) { try { var … Read more

Have the client store this key in a cookie. On socket connect (or anytime later) fetch this key from the cookie and send it back to the server. Fetch … Read more
