What is caching-transform?

The caching-transform npm package is designed to cache the results of expensive transformation operations, such as those performed during the build or compilation process. It works by storing the results of these operations in a cache, keyed by a hash of the input. This means that if the input hasn't changed, the transformation can be skipped, and the cached result can be used instead. This can significantly speed up build times in development environments or for repeated builds.

What are caching-transform's main functionalities?

Caching file transformations

This code demonstrates how to use caching-transform to cache the results of a file transformation. The `transform` function represents an expensive operation. The `cache` function, created by `cachingTransform`, checks if a cached result exists for the given input. If not, it runs the transformation and caches the result.

const cachingTransform = require('caching-transform');
const fs = require('fs');
const path = require('path');

const cacheDir = path.join(__dirname, '.cache');

const transform = (input) => {
  // Perform an expensive transformation here
  return transformedInput;
};

const cache = cachingTransform({
  cacheDir: cacheDir,
  transform: transform
});

const input = fs.readFileSync('input.txt', 'utf8');
const output = cache(input);
console.log(output);
