mako-cache

mako-cache

A helper for reading/writing build caches.

This helper encapsulates the logic for loading and saving mako build cache files.

Usage

var cache = require('mako-cache');

// read a build tree from disk
cache.load().then(function (tree) {
  // tree can be passed to a mako runner
});

// save a build tree to disk
cache.save(tree).then(function () {
  // multiple writes will be queued, so they don't clobber one another
});

API

This API returns promises, except in the case of the documented sync functions.

cache.load(root)

Using the given project root, a cache file will be looked for in the mako cache folder. (in the OS temp directory) If found, it will be unserialized and returned as a Tree instance that can be given to a mako runner.

If no root is specified, it will assume you meant pwd.

If the given file does not exist, it will simply return null rather than throwing an error.

cache.loadSync(root)

The same as cache.load(root), except it is synchronous.

cache.save(tree)

Saves the given tree to the mako cache folder. (in the OS temp directory) The contents of file are a gzipped JSON representation of the tree.

cache.saveSync(tree)

The same as cache.save(tree), except it is synchronous.

cache.clear([root])

Used to clear out the mako cache folder. If a root is specified, only that project's cache file will be deleted. If no root is specified, the entire folder will be deleted.

cache.clearSync([root])

The same as cache.clear([root]), except it is synchronous.

cache.path(root)

Returns the calculated path to the file that the project root would have.
