Read File List
Read the entire contents of each file in a file list.
Usage
var readFileList = require( '@stdlib/fs/read-file-list' );
readFileList( filepaths[, options], clbk )
Asynchronously reads the entire contents of each file in a file list.
readFileList( [ __filename ], onFiles );
function onFiles( error, files ) {
if ( error ) {
throw error;
}
console.dir( files );
// => [{...}]
}
Each file is represented by an object
with the following fields:
- file: file path.
- data: file contents as either a
Buffer
orstring
.
The function accepts the same options as readFile()
.
readFileList.sync( filepaths[, options] )
Synchronously reads the entire contents of each file in a file list.
var out = readFileList.sync( [ __filename ] );
if ( out instanceof Error ) {
throw out;
}
console.dir( out );
// => [{...}]
The function accepts the same options as readFile.sync()
.
Examples
var readFileList = require( '@stdlib/fs/read-file-list' );
/* Sync */
var files = readFileList.sync( [ __filename ], 'utf8' );
// returns <ObjectArray>
console.log( files instanceof Error );
// => false
files = readFileList.sync( [ 'beepboop' ], {
'encoding': 'utf8'
});
// returns <Error>
console.log( files instanceof Error );
// => true
/* Async */
readFileList( [ __filename ], onFiles );
readFileList( [ 'beepboop' ], onFiles );
function onFiles( error, files ) {
if ( error ) {
if ( error.code === 'ENOENT' ) {
console.error( 'A file does not exist.' );
} else {
throw error;
}
} else {
console.dir( files );
}
}
