wrap a readable/writable stream to be read-only
npm install read-only-streamwrap a readable/writable stream to be read-only
to prevent mucking up the input side
Suppose you have a module that uses a readable/writable stream internally but
want to expose just the readable part of that internal stream. This is common if
you use the writable side internally and expose the readable side as the
interface.
Now we can write some code like this with a through stream internally for
convenience:
`` js
var through = require('through2');
var readonly = require('read-only-stream');
module.exports = function () {
var stream = through();
stream.end('wooooo\n');
return readonly(stream);
};
`
but consumers won't be able to write to the input side and break the api:
` jsro
var wrap = require('./wrap.js');
var ro = wrap(); // can't write to and muck up internal state`
ro.pipe(process.stdout);
` js`
var readonly = require('read-only-stream')
Return a readable stream ro that wraps the readable/writable stream argument
given to only expose the readable side.
stream can be a streams1 or streams2 stream.
With npm do:
`
npm install read-only-stream
