Sometimes, we want to read all files in a directory, store them in objects, and send the object with Node.js.
In this article, we’ll look at how to read all files in a directory, store them in objects, and send the object with Node.js.
How to read all files in a directory, store them in objects, and send the object with Node.js?
To read all files in a directory, store them in objects, and send the object with Node.js, we can use the readdir and readFile methods.
For instance, we write
const fs = require('fs');
fs.readdir(dirname, (err, filenames) => {
if (err) {
onError(err);
return;
}
filenames.forEach((filename) => {
fs.readFile(dirname + filename, 'utf-8', (err, content) => {
if (err) {
onError(err);
return;
}
onFileContent(filename, content);
});
});
});
to call fs.readdir to read the file paths from the dirname folder.
Then we get the filenames array from the callback parameter.
And then we call filenames.forEach with a callback that calls fs.readFile to read file with path dirname + filename.
And we get the content of the file from the content parameter in the readFile callback.
Conclusion
To read all files in a directory, store them in objects, and send the object with Node.js, we can use the readdir and readFile methods.
