项目是多入口(多页面),每次修改代码,热加载都很慢,定格在 94% asset optimization
持续5秒左右,页面才更新内容。这个应该是webpack存在的问题。
我发现减少页面数量,热加载会明显相应的减少耗时。我怀疑每次修改内容会对全部代码进行某些检查或处理,从而增加了热加载完成的时间,但是找了很多资料还是没找到真正原因。
这是依赖版本号:
"webpack": "^3.6.0", "webpack-bundle-analyzer": "^2.9.0", "webpack-dev-server": "^2.9.1", "webpack-merge": "^4.1.0" "uglifyjs-webpack-plugin": "^1.1.1", "optimize-css-assets-webpack-plugin": "^3.2.0", "hard-source-webpack-plugin": "^0.6.4", "html-webpack-plugin": "^2.30.1", "extract-text-webpack-plugin": "^3.0.0", "copy-webpack-plugin": "^4.0.1",
相应部分代码:
for (var pathname in pages) { var conf = { filename: pathname + '.html', template: pages[pathname], inject: true }; if (pathname in devWebpackConfig.entry) { conf.chunks = ['manifest', 'vendors', pathname]; conf.hash = true; } devWebpackConfig.plugins.push(new HtmlWebpackPlugin(conf)); }
