read-all-stdin-sync

Save one level of indentation in scripts that won't do anything anyway until they've read all of stdin.

Caveats

Only works if data can be read from stdin right away, e.g. reading from a ready file handle.
- If stdin isn't ready, expect Error: EAGAIN: resource temporarily unavailable, read
- We can't just wait and retry in sync mode because Node probably won't do I/O if we sleep.

var data = require('read-all-stdin-sync')();
console.dir(Object.keys(JSON.parse(data)));

If you want to get rid of a possible leading Byte-Order Mark:

var data = require('read-all-stdin-sync')({ stripBOM: true });
console.dir(Object.keys(JSON.parse(data)));

Actually, there's a shorthand for BOM stripping and parsing JSON:

var data = require('read-all-stdin-sync')(JSON);
console.dir(Object.keys(data));

You can read buffers, too:

var data = require('read-all-stdin-sync')({ encoding: null });
console.dir(data);

Easier to remember:

var data = require('read-all-stdin-sync')(Buffer);
console.dir(data);
