I'm trying to add this plugin, which is uses this webpack plugin to my craco config file, followed the guide but it's not working.
const CracoAlias = require('craco-alias');
const imageOptimizer = require('craco-image-optimizer-plugin');
module.exports = function ({ env }) {
return {
reactScriptsVersion: 'react-scripts',
style: {
postcss: {
plugins: [
require('tailwindcss'),
require('postcss-focus-visible'),
require('autoprefixer'),
],
},
},
plugins: [
{
plugin: imageOptimizer,
// image-webpack-plugin options
options: {
mozjpeg: {
progressive: true,
quality: 65,
},
// optipng.enabled: false will disable optipng
optipng: {
enabled: false,
},
pngquant: {
quality: [0.65, 0.9],
speed: 4,
},
gifsicle: {
interlaced: false,
},
// the webp option will enable WEBP
webp: {
quality: 75,
},
},
},
{
plugin: CracoAlias,
options: {
//CracoAlias options
},
},
],
};
};
The plugin is supposed to optimize the images, but it's not happening. Any ideas? Is it something wrong with my config file? Thanks.
Seems like it was a problem with react-scripts. Had to add the plugin manually like this:
const { getLoaders, loaderByName } = require('#craco/craco');
module.exports = {
overrideWebpackConfig: ({ webpackConfig, cracoConfig, pluginOptions }) => {
const config = { ...webpackConfig };
const urlLoaderCandidates = getLoaders(config, loaderByName('url-loader'));
const urlLoader = urlLoaderCandidates.matches.find(
m =>
m.loader &&
m.loader.test &&
(Array.isArray(m.loader.test)
? m.loader.test.some(r => r.toString().indexOf('jpe?g') >= 0)
: m.loader.test.toString().indexOf('jpe?g') >= 0)
);
if (!urlLoader) {
throw Error(
'could not find correct url-loader. did you change react-scripts version?'
);
}
const loader = urlLoader.loader;
loader.use = [
{
loader: loader.loader,
options: Object.assign({}, loader.options),
},
{
/**
* #see https://github.com/tcoopman/image-webpack-loader
*/
loader: 'image-webpack-loader',
options: pluginOptions,
},
];
delete loader.loader;
delete loader.options;
return config;
},
};
And then import the file instead of the package.
I am trying to add the loadable components library for code splitting in my React universal app. I have CSS modules in my project, and it used to work fine. But then I added the loadable component library for code splitting. Now the server is working, but the CSS is not, and the pages are loading without CSS. I have checked the stats.json file and it is missing the CSS files.

css modules works fine with client side and worked fine without code splitting in server side but not working with loadable components. i am using cra-universal library for server side rendering.
can someone please help me with this issue and it will be greatly appreciated.
I'm trying to reduce the bundle size of my site by using https://www.npmjs.com/package/#next/bundle-analyzer
At the moment, when I run npm analyze with
"analyze": "cross-env ANALYZE=true next build",
It isn't outputting the html files with the visualization needed.
This is my next.config.js
const withPWA = require('next-pwa')
const runtimeCaching = require('next-pwa/cache')
const withBundleAnalyzer = require('#next/bundle-analyzer')({
enabled: process.env.ANALYZE === 'true',
})
module.exports = withPWA({
pwa: {
dest: 'public',
runtimeCaching,
},
poweredByHeader: false,
},
withBundleAnalyzer(),
)
using this nextjs-analyze-app-bundle tutorial.
What is going wrong?
Looks like this has been answered on Vercel's issues board. Copying their solution here:
These plugins are functions that enhance the configuration object, so
you have to wrap them instead of providing them as arguments:
const withPWA = require('next-pwa')
const runtimeCaching = require('next-pwa/cache')
const withBundleAnalyzer = require('#next/bundle-analyzer')({
enabled: process.env.ANALYZE === 'true',
});
module.exports = withBundleAnalyzer(withPWA({
pwa: {
dest: 'public',
runtimeCaching,
},
poweredByHeader: false,
}));
Before I was doing it like this,
module.exports = withBundleAnalyzer(
withPWA({
pwa: {
dest: 'public',
runtimeCaching,
},
poweredByHeader: false,
})
)
module.exports =
{
env: {
BASE_URL: process.env.BASE_URL,
},
future: {
webpack5: true,
},
reactStrictMode: true,
}
Not sure but I think you should only need to have one module.exports so I wrapped my other stuff inside the withBundleAnalyzer like this
module.exports = withBundleAnalyzer(
withPWA({
pwa: {
dest: 'public',
runtimeCaching,
},
poweredByHeader: false,
}),
{
env: {
BASE_URL: process.env.BASE_URL,
},
future: {
webpack5: true,
},
reactStrictMode: true,
}
)
