Example

const filePathFilter = require("file-path-filter");

const paths = [
  "/some/path/index.html",
  "/some/path/contact.html",
  "/some/path/about.html",
  "/some/path/favicon.ico",
  "/some/path/img/logo.png",
];

// Filter using a glob pattern
paths.filter(filePathFilter("**/*.html"));

// Exclude glob patterns with "!"
paths.filter(filePathFilter("**/*.html", "!**/index.html"));

// Filter using a regular expression
paths.filter(filePathFilter(/\.(ico|png)$/));

// Filter using custom criteria
paths.filter(filePathFilter(path => path.length === 23));

// Use any combination of filters
paths.filter(filePathFilter([
  "**/*.html",
  "!**/index.html",
  /\.(ico|png)$/,
  path => path.length === 23
]));

// Explicitly specify include and exclude criteria
paths.filter(filePathFilter({
  include:  [
    "**/*.html",
    /\.(ico|png)$/,
    path => path.length === 23
  ],
  exclude: "**/index.html",
));

Installation

You can install file-path-filter via npm.

npm install file-path-filter

Usage

filePathFilter(criteria)

createFilter(options, criteria)

The createFilter function is an alternative to the filePathFilter function that allows you to customize the behavior to suit your needs.

Filtering objects

The filePathFilter function creates a function that filters arrays of strings, but what if you need to filter an array of objects instead? That’s where the map option comes in handy. You can use it to map objects (or any other value) to file paths. Here’s an example:

const { createFilter } = require("file-path-filter");
const path = require("path");

const files = [
  { dir: "/my/website", filename: "index.html" },
  { dir: "/my/website", filename: "contact.html" },
  { dir: "/my/website/blog", filename: "post-1.html" },
  { dir: "/my/website/blog", filename: "post-2.html" },
];

// A function to returns the path of each file
function map(file) {
  return path.join(file.dir, file.filename);
}

// Filter the file objects - return all HTML files except the blog posts
files.filter(createFilter({ map }, "**/*.html", "!**/blog/*.html"));
