Support dynamic require

[sindresorhus]

Many modules uses require to dynamically load JSON files.

Example:

require('./path/' + name + '.json');

[ghost]

This is pretty tricky but might be possible in some cases where name is statically resolvable. I think a static resolver module would be the best way to implement this.

Another usecase (from cheerio):

var api = ['attributes', 'traversing', 'manipulation'];

api.forEach(function(mod) {
  _.extend(Cheerio.prototype, require('./api/' + mod));
});

Probably more of a browsersify core issue, but it does seem slightly related.

The sledge hammer approach taken by nodejitsu/require-analyzer is to first check if all requires can be resolved statically, and if they can't, fire up a new node instance, monkey-patch Module#require and track everything that's required.

While this would certainly work for browserify, it might complicate the development process, as the compilation thread in the background might run into an infinite loop and block the system.

browserify should at least add support for statically resolving variables, plus some of the array extras. Especially map is interesting here, as I can imagine using ES6 destructuring expressions to require multiple modules at once will become a common pattern:

let [fs, path] = ["fs", "path"].map(require)

I have this use case

[ 'a.js', 'b.js' ].forEach(js => {
  injectJS(fs.readFileSync(js));
});

I had this issue too, but as said before, couldn't achieve this with brfs. What I did was a simply fetch request. Would it be possible to replace

fs.readFile('posts/' + post + '.md', function (err, content) {
  // process file
})

with

fetch('posts/' + post + '.md')
   .then(response => response.text())
   .then(content => {
     // process file
   })

So it would dynamically load files with ajax?

@YerkoPalma even better now:

var content = (await fetch(`posts/${post}.md`)).text()

[goto-bus-stop]

@dy fetch()'s return value doesn't have a .text() method, so with async/await you have to do something like

var resp = await fetch(`posts/${post}.md`)
var content = await resp.text()
