Cache Loader

-

Caches the result of following loaders on disk (default) or in the database

-
- -

Install

- -```bash -npm install --save-dev cache-loader -``` - -

Usage

- -Add this loader in front of other (expensive) loaders to cache the result on disk. - -**webpack.config.js** -```js -module.exports = { - module: { - rules: [ - { - test: /\.ext$/, - use: [ - 'cache-loader', - ...loaders - ], - include: path.resolve('src') - } - ] - } -} -``` - -> ⚠️ Note that there is an overhead for saving the reading and saving the cache file, so only use this loader to cache expensive loaders. - -

Options

- -|Name|Type|Default|Description| -|:--:|:--:|:-----:|:----------| -|**`cacheKey`**|`{Function(options, request) -> {String}}`|`undefined`|Allows you to override default cache key generator| -|**`cacheDirectory`**|`{String}`|`path.resolve('.cache-loader')`|Provide a cache directory where cache items should be stored (used for default read/write implementation)| -|**`cacheIdentifier`**|`{String}`|`cache-loader:{version} {process.env.NODE_ENV}`|Provide an invalidation identifier which is used to generate the hashes. You can use it for extra dependencies of loaders (used for default read/write implementation)| -|**`write`**|`{Function(cacheKey, data, callback) -> {void}}`|`undefined`|Allows you to override default write cache data to file (e.g. Redis, memcached)| -|**`read`**|`{Function(cacheKey, callback) -> {void}}`|`undefined`|Allows you to override default read cache data from file| - -

Examples

- -**webpack.config.js** -```js -module.exports = { - module: { - rules: [ - { - test: /\.js$/, - use: [ - 'cache-loader', - 'babel-loader' - ], - include: path.resolve('src') - } - ] - } -} -``` - -### `Database Integration` - -**webpack.config.js** -```js -// Or different database client - memcached, mongodb, ... -const redis = require('redis'); -const crypto = require('crypto'); - -// ... -// connect to client -// ... - -const BUILD_CACHE_TIMEOUT = 24 * 3600; // 1 day - -function digest(str) { - return crypto.createHash('md5').update(str).digest('hex'); -} - -// Generate own cache key -function cacheKey(options, request) { - return `build:cache:${digest(request)}`; -} - - -// Read data from database and parse them -function read(key, callback) { - client.get(key, (err, result) => { - if (err) { - return callback(err); - } - - if (!result) { - return callback(new Error(`Key ${key} not found`)); - } - - try { - let data = JSON.parse(result); - callback(null, data); - } catch (e) { - callback(e); - } - }); -} - - -// Write data to database under cacheKey -function write(key, data, callback) { - client.set(key, JSON.stringify(data), 'EX', BUILD_CACHE_TIMEOUT, callback); -} - -module.exports = { - module: { - rules: [ - { - test: /\.js$/, - use: [ - { - loader: 'cache-loader', - options: { - cacheKey, - read, - write, - } - }, - 'babel-loader' - ], - include: path.resolve('src') - } - ] - } -} -``` - -
