Search files with glob pattern and read them, Observable way
``javascript
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; //=>
},
complete() {
console.log('Glob completed.');
}
});
`
`
npm install read-glob
`javascript`
const readGlob = require('read-glob');
pattern: string (glob pattern) Object
options: ([node-glob] and [fs.readFile] options) or string (encoding) Observable
Return: (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.
`javascript
readGlob('hi.txt').subscribe(result => {
result.contents; //=>
});
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.
`javascript
const readGlob = require('read-glob');
// ./directory/.dot.txt: 'Hello'
readGlob('*.txt', {
cwd: 'directory',
dot: true
}).subscribe(({contents}) => {
contents.toString(); //=> 'Hello'
});
`
* read-glob-promise (Promise version)
