I am having a bit of trouble reconciling the path of a dynamic import for i18n locales. Here's the relevant code -
function getLoader(
lang: SupportedLanguage,
ns: SupportedNamespace
): NamespaceLoader | undefined {
const matrixToCheck = UNSUPPORTED_MATRIX[ns];
const isSupported = matrixToCheck && matrixToCheck.indexOf(lang) === -1;
if (isSupported) {
const path = `./locales/${lang}/${ns}.json`;
const name = `${lang}_${ns}`;
const named = {
[name]: () => import(`${path}`),
};
return named[name];
}
}
...
// eventual output
const SUPPORTED_LANGUAGES = {en: {namespace1: () => import('./locales/en/namespace1.json')}
My goal is manage all of the relevant translations in a single npm package, handle all of the dynamic import set-up at build time, and then consumers can invoke the getter (getTranslation in this case) in their respectives apps for the language and namespace of their choice to get the payload at runtime.
Based on this GH thread, I wanted to reconcile the locale dist path via the package.json
...
"exports": {
".": "./dist/src/main.js",
"./": "./dist/"
},
...
e.g. when I publish the package, based on that exports config, the consumer would know know how to reconcile the path, either relative or package-name-prefix when the getter is invoked
const fn = () => import('./locales/fr/myNamespace.json') /// doesn't work
const anotherFn = () => import('#examplePackageName/locales/fr/myNamespace.json') /// doesn't work
Since everything is dynamic, I am using the CopyWebpackPlugin to include the locales in the dist folder.
This works as expected locally, but when I create the dist, I get the error Error: Module not found ./relative/path/to/the/json/I/want.json.
My question:
What am I missing? Is there a simple way to expose these translations so that other apps can include them in their bundles via an npm-installed package?
Here's my Webpack config, happy to provide other info as needed
const path = require("path");
const CopyPlugin = require("copy-webpack-plugin");
const { CleanWebpackPlugin } = require("clean-webpack-plugin");
const getPlugins = () => {
return [
new CleanWebpackPlugin(),
new CopyPlugin({
patterns: [{ from: "locales", to: "locales" }],
}),
];
};

Exports directive prescribes to define all files allowed for import explicitly (documentation). It allows developer to hide internal package file structure. What's not exported by this directive is only available to import inside the package and not outside of it. It's made to simplify maintenance. It allows developers to rename files or change file structure without fear of breaking dependent packages and applications.
So if you want to make internal files visible for import, you should export them with exports directive explicitly, like this:
{
"exports": {
".": "./dist/esm/src/main.js",
"./dist/shared/locale/fr_fr.json": "./dist/shared/locale/fr_fr.json"
}
}
I'm not sure wether Webpack handling this case, because it's an experimental feature yet. But this is how Node.js works now.
Why it is so
Changing your app file structure is a major change in semver terms, so you need to bump a version everytime you rename or delete files. To avoid it you can specify which files are part of public interface of the package.
below code is my webpack.config.dev.js.
I got the webpack config after running npm run eject as you might already know.
I installed node-sass and sass-loader packages.
I included the webpack build configuration.
When I run npm start I get invalid schema error. If I try to fix this I get
module export error for bootstrap 4 module that I had already included in the project.

I'm trying to get some basic benchmark tests working and am having trouble figuring out the right configuration. I'm trying to use Benchmarkjs with webpack and babel to transpile my code to es5. I created a benchmarks.webpack.js as an entry point which looks like this:
var context = require.context('./src/js', true, /-benchmark\.js$/);
context.keys().forEach(context);
module.exports = context;
I then have a benchmark file that I want to run (test-benchmark.js):
import benchmark from 'benchmark';
import benchmarks from 'beautify-benchmark';
let suite = new benchmark.Suite;
suite.add('RegExp#test', function() {
/o/.test('Hello World!');
})
.add('String#indexOf', function() {
'Hello World!'.indexOf('o') > -1;
})
.on('cycle', function(event) {
benchmarks.add(event.target);
})
.on('complete', function() {
benchmarks.log();
})
.run();
I updated my webpack build to try and transpile the benchmarks:
_.assign(config, {
devtool: 'eval-cheap-module-source-map',
output: {
path: path.join(__dirname, 'build/benchmark'),
filename: 'benchmark.js',
publicPath: '/'
},
entry: [
'./benchmarks.webpack.js'
],
plugins: [
],
module: {
loaders: [
{
test: /\.js$/,
loaders: ['babel?stage=0'],
include: path.join(__dirname, 'src/js')
},
]
},
});
Finally, I want to be able run this from an npm script:
"scripts": {
"bench": "webpack --config webpack.bench.config.js && node build/benchmark/benchmark.js"
},
However, I'm getting warnings that the result of the benchmark dependency is an expression and there no suitable loaders for the .json, .txt, etc files. I tried hacking up Benchmarkjs to export correctly but was not successful.

# ./~/benchmark ^\.\/.*$
Looks like benchmark does something special with require. That messes it up for Webpack. It has the following lines:
var freeRequire = typeof require == 'function' && require;
...
function req(id) {
try {
var result = freeExports && freeRequire(id);
} catch(e) { }
return result || null;
}
If you comment out the function contents, the error goes away. Given it's not ideal to patch around it this way I would poke the benchmark guys about this directly instead. Perhaps there's something we're missing.
I'm struggling to get requirejs to work after optimizing with r.js
It works fine pre optimization
I'm following the docs for configuring main.js and the build profile using empty:
However after optimization, CDN scripts are no longer loaded.
public/index.html
<script data-main="editor/js/main" src="editor/js/vendor/require.js"></script>
public/editor/js/main.js
requirejs.config({
baseUrl: "/editor/js",
paths: {
"jquery": "http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min",
"order": "vendor/require_order",
"underscore": "vendor/underscore",
"handlebars": "vendor/handlebars-1.0.0.beta.4",
"jquery.mobile.router": "vendor/jquery.mobile.router",
"jquery.mobile": "http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min"
}
});
require(["order!jquery", "order!underscore", "order!handlebars", "order!jam", "order!jquery.mobile"], function () {
//loaded
});
config/build.js
({
baseUrl: "../public/editor/js",
name: "main",
out: "../public/editor/js/main-built.js",
paths: {
"order": "vendor/require_order",
"underscore": "vendor/underscore",
"handlebars": "vendor/handlebars-1.0.0.beta.4",
"jquery.mobile.router": "vendor/jquery.mobile.router",
"jquery": "empty:",
"jquery.mobile": "empty:"
}
})
When I run r.js node config/r.js -o config/build.js
main-built.js is built successfully.
Is there a particular reason why you are loading everything using the order plugin?
Were you having load order problems in your built javascript?
If you load jQuery mobile normally (without the plugin) your "empty" configuration should take effect.
require(["jquery", "underscore", "handlebars", "jam", "jquery.mobile"], function () {
http://requirejs.org/docs/optimization.html#empty
You will also need to define the dependency chain for jQuery.mobile.router
requirejs.config({
paths: {
"jquery": "http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min",
"order": "vendor/require_order",
"underscore": "vendor/underscore",
"handlebars": "vendor/handlebars-1.0.0.beta.4",
"jquery.mobile.router": "vendor/jquery.mobile.router",
"jquery.mobile": "http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min"
},
shim: {
"router": {
"deps" : ["jquery.mobile"]
},
"jquery.mobile" : {
"deps" : [ "jquery.mobile.router"],
"exports": "$.mobile"
},
"jquery.mobile.router": {
"exports": "$.mobile.Router"
}
}
});
see the answer to this question:
Require.js with jQueryMobile-Router
I hope that resolves your issues with requirejs, I've found it to be a very powerful and useful tool, once you get used to its structure.
