Package Exports
- read-multiple-files
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (read-multiple-files) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
read-multiple-files
Read multiple files Observable way
const readMultipleFiles = require('read-multiple-files');
readMultipleFiles(new Set([
'one.txt', // 'a'
'another.txt' // 'b'
])).subscribe({
next(result) {
if (result.path === 'one.txt') {
result.contents; // Buffer.from('a')
} else if (result.path === 'another.txt') {
result.contents; // Buffer.from('b')
}
},
complete() {
console.log('Successfully read all files.');
}
});Installation
npm install read-multiple-filesAPI
const readMultipleFiles = require('read-multiple-files');readMultipleFiles(paths [, options])
paths: <Array|Set<string|Buffer|URL|integer>> (file paths)
options: Object (fs.readFile options) or string (encoding)
Return: Observable (zenparsing's implementation)
When the Observable is subscribed, it starts to read files in parallel, successively send each result to its Observer as an Object: {path: <string|Buffer|URL|integer>, contents: <string:Buffer>}
readMultipleFiles([
'foo.txt', // 'Hello'
'bar.txt' // 'World'
], 'utf8').subscribe({
next({path, contents}) {
if (path === 'one.txt') {
contents; // 'Hello'
} else if (path === 'another.txt') {
contents; // 'World'
}
}
});The Observer receives an error when it fails to read at least one of the files.
const readMultipleFiles = require('read-multiple-files');
readMultipleFiles([
'foo.txt', // exists
'bar.txt' // doesn't exist
]).subscribe({
error(err) {
err.code; //=> ENOENT
},
complete() {
// `complete` callback will never be called.
}
