webpack 打包性能优化
开启多线程打包 thread-loader
https://www.npmjs.com/package/thread-loader
https://github.com/webpack-contrib/thread-loader
module.exports = {
module: {
rules: [
{
test: /\.js$/,
include: path.resolve('src'),
use: [
'thread-loader',
// your expensive loader (e.g babel-loader)
],
},
],
},
};
use: [
{
loader: 'thread-loader',
// loaders with equal options will share worker pools
options: {
// the number of spawned workers, defaults to (number of cpus - 1) or
// fallback to 1 when require('os').cpus() is undefined
workers: 2,
// number of jobs a worker processes in parallel
// defaults to 20
workerParallelJobs: 50,
// additional node.js arguments
workerNodeArgs: ['--max-old-space-size=1024'],
// Allow to respawn a dead worker pool
// respawning slows down the entire compilation
// and should be set to false for development
poolRespawn: false,
// timeout for killing the worker processes when idle
// defaults to 500 (ms)
// can be set to Infinity for watching builds to keep workers alive
poolTimeout: 2000,
// number of jobs the poll distributes to the workers
// defaults to 200
// decrease of less efficient but more fair distribution
poolParallelJobs: 50,
// name of the pool
// can be used to create different pools with elsewise identical options
name: 'my-pool',
},
},
// your expensive loader (e.g babel-loader)
];
prewarming 预热
const threadLoader = require('thread-loader');
threadLoader.warmup(
{
// pool options, like passed to loader options
// must match loader options to boot the correct pool
},
[
// modules to load
// can be any module, i. e.
'babel-loader',
'babel-preset-es2015',
'sass-loader',
]
);
为防止启动工作程序时出现高延迟，可以预热工作程序池。
这将引导池中的最大工作程序数量，并将指定的模块加载到node.js模块高速缓存中。
