This module allows proper integration with webpack, with support for proper assets reloading in development and asset hashes for production caching.
This module is compatible with webpack 1.0 to 4.0
For webpack 4 use this example config file: https://github.com/go-webpack/examples/blob/master/config/webpack.config.js (the only thing required for go-webpack is ManifestPlugin - the rest is my personal example config)
Are here
- Switch to go 1.11 modules
- Various refactoring
- Change default to stats plugin, to use StatsPlugin set it manually
webpack.Plugin = "stats" - Update examples, add pongo2, gin and gin-render examples
- Don't fail if manifest is not present in development mode
- less noisy (remove some logs on verbose)
- 2018-11-10 Fix globals usage and add some tests #4 thx @toshok
- 2018-11-10 tweak iris example #3 thx @vosmith
- assorted refactoring
- 2018-09-12 Add ability to use multiple webpack manifests per app
- 2018-07-17 Don't hardcode manifest path (thx @rodumani)
- 2018-07-17 Deprecate stats plugin default, specify plugin explicitly to continue using it.
- 2018-07-17 Pretty print manifest content
- 2018-02-13 Move examples to separate repo
- 2018-02-09 Refactor & cleanup code, add support for ManifestPlugin instead of outdated StatsPlugin (see new examples)
- 2017-08-09 Now reports if you didn't call webpack.Init() to set working mode properly
- 2017-03-07 Initial version / extraction

for qor/render, other would be similar

- Configure webpack to serve manifest.json via
StatsPluginManifestPlugin - Call
webpack.Plugin = "manifest"to set go-webpack to use ManifestPlugin, don't call to use old StatsPlugin - Call
webpack.Init()to set development or production mode. - Add webpack.AssetHelper to your template functions.
- Call helper function with the name of your asset
Use webpack.config.js (and package.json) from this repo or create your own.
The only thing that must be present in your webpack config is StatsPlugin ManifestPlugin which is required to serve assets the proper way with hashes, etc.
Your compiled assets is expected to be at public/webpack and your webpack-dev-server at http://localhost:3808
When run with -dev flag, webpack asset manifest is loaded from http://localhost:3808/webpack/manifest.json, and updated automatically on every request. When running in production from public/webpack/manifest.json and is persistently cached in memory for performance reasons.
Examples moved to separate repo here
cd examples
yarn install # or npm install
# for development mode
yarn start
# or ./node_modules/.bin/webpack-dev-server --config webpack.config.js --hot --inline
# Or for production mode
yarn build
# or ./node_modules/.bin/webpack --config webpack.config.js --bail
# start backend
go get
go run iris/main.go -dev
go run qor/main.go -dev
If all is working, you will see a JS alert message.
NODE_ENV=production ./node_modules/.bin/webpack --config webpack.config.js
Don't forget to set go-webpack to production mode (webpack.Init(false))
var DevHost = "localhost:3808" - webpack-dev-server host:port var FsPath = "public/webpack" - filesystem path to public webpack dir var WebPath = "webpack" - http path to public webpack dir var Plugin = "stats" - webpack plugin to use, can be stats or manifest var IgnoreMissing = true - ignore assets missing on manifest or fail on them var Verbose = true - print error messages to console (even if error is ignored)
