Application programming interface

Although it is recommended to use the command line interface or the Gulp plugin to process your PHP files, you can use the functionality of this package directly in your JavaScript code.

Here is an example of how to use it:

import {FastTransformer, SafeTransformer, TransformMode} from "@cedx/php-minifier";
import console from "node:console";
import {mkdir, readdir, writeFile} from "node:fs/promises";
import {dirname, extname, join, relative} from "node:path";
import {env, loadEnvFile} from "node:process";

// Choose an appropriate transformer.
loadEnvFile();
await using transformer = env.PHPMINIFIER_MODE == TransformMode.Fast ? new FastTransformer : new SafeTransformer;

// Scan the input directory for PHP files.
const input = "path/to/source/folder";
const files = (await readdir(input, {recursive: true, withFileTypes: true}))
  .filter(item => item.isFile() && extname(item.name) == ".php");

// Write the transformed files to the output directory.
const output = "path/to/destination/folder";
for (const file of files) {
  const fullPath = join(file.parentPath, file.name);
  const relativePath = relative(input, fullPath);
  console.log(`Minifying: ${relativePath}`);

  const script = await transformer.transform(fullPath);
  const target = join(output, relativePath);
  await mkdir(dirname(target), {recursive: true});
  await writeFile(target, script);
}
