Introducing Java Support in Socket
We're excited to announce that Socket now supports the Java programming language.
detect-file
Advanced tools
The detect-file npm package is designed to help developers determine if a file exists in a given path. It provides a simple and efficient way to check for the presence of files without having to manually handle file system operations. This can be particularly useful in build scripts, file validation processes, or any scenario where ensuring the existence of a file is necessary.
Check if a file exists
This feature allows you to check if a specific file exists at a given path. The function returns a boolean indicating the presence of the file.
const detectFile = require('detect-file');
const filePath = 'path/to/your/file.txt';
const exists = detectFile(filePath);
if (exists) {
console.log('File exists.');
} else {
console.log('File does not exist.');
}
fs-extra is a package that builds on the native fs module, providing additional methods to interact with the file system. It includes a method called 'pathExists' which can be used to check if a file exists, similar to detect-file. However, fs-extra offers a broader range of file system operations, making it more versatile.
file-exists is another npm package that offers functionality similar to detect-file, specifically focused on checking the existence of files. While both packages serve a similar purpose, file-exists provides both synchronous and asynchronous APIs, giving developers more flexibility in how they perform the check.
Detects if a file exists and returns the resolved filepath.
Install with npm:
$ npm install --save detect-file
Install with yarn:
$ yarn add detect-file
var detect = require('detect-file');
Detect the given filepath
if it exists.
Params
filepath
{String}: filepath to detect.options
{Object}: Additional options.options.nocase
{Boolean}: Set this to true
to force case-insensitive filename checks. This is useful on case sensitive file systems.returns
{String}: Returns the detected filepath if it exists, otherwise returns null
.Example
var res = detect('package.json');
console.log(res);
//=> "package.json"
var res = detect('fake-file.json');
console.log(res)
//=> null
When using the nocase
option, this library will attempt to detect the filepath with the following methods:
filepath
using fs.readdirSync
. If successful and filepath
is a directory, return the filepath
.filepath
's directory using fs.readdirSync
. If successful, do case insensitive comparasions of the filepath
to the files in filepath
's directory.fs-exists-sync: Drop-in replacement for fs.existsSync
with zero dependencies. Other libs I found either have crucial differences… more | homepage
