read-glob

Search files with glob pattern and read them, Observable way

const readGlob = require('read-glob');

readGlob('src/*.js').subscribe({
  start() {
    console.log('Glob started.');
  },
  next(result) {
    result.cwd; //=> '/Users/shinnn/exmaple'
    result.path; //=> 'src/a.js'
    result.contents; //=> <Buffer ... >
  },
  complete() {
    console.log('Glob completed.');
  }
});

Installation

Use npm.

npm install read-glob

API

const readGlob = require('read-glob');

readGlob(pattern [, options])

pattern: string (glob pattern)
options: Object (node-glob and fs.readFile options) or string (encoding)
Return: Observable (zenparsing's implementation)

When the Observable is subscribed, it starts to search files matching the given glob pattern, read their contents and successively send results to its Observer.

Results

Each result is the same Object as glob-observable's with the additional contents property, a Buffer or string of the matched file contents.

contents is a string when the encoding option is specified, otherwise it's a Buffer.

readGlob('hi.txt').subscribe(result => {
  result.contents; //=> <Buffer 48 69>
});

readGlob('hi.txt', 'utf8').subscribe(result => {
  result.contents; //=> 'Hi'
});

readGlob('hi.txt', 'base64').subscribe(result => {
  result.contents; //=> 'SGk='
});

options

The option object will be directly passed to node-glob and fs.readFile, or the encoding string sets the encoding of fs.readFile.

Unlike the original node-glob API,

silent and strict options are true by default.
nodir and mark options are not supported as it ignores directories by default.

const readGlob = require('read-glob');

// ./directory/.dot.txt: 'Hello'

readGlob('*.txt', {
  cwd: 'directory',
  dot: true
}).subscribe(({contents}) => {
  contents.toString(); //=> 'Hello'
});
