razzle-dev-utils
Advanced tools
This package includes some utilties used by Razzle
These utilities come by default with Razzle, which includes it by default. You don’t need to install it separately in Razzle projects.
If you don’t use Razzle, you may keep using these utilities. Their development will be aligned with Razzle, so major versions of these utilities may come out relatively often. Feel free to fork or copy and paste them into your projects if you’d like to have more control over them, or feel free to use the old versions.
There is no single entry point. You can only import individual top-level modules.
logger
logger.log(thing: any): void
: Log to console. = console.log
logger.start(text: string): void
: Log the start of a task to consolelogger.done(text: string): void
: Log the end of task to consolelogger.info(text: string, data: object): void
: Log information and data to consolelogger.debug(text: string, data: object): void
: Log debug message and data to consolelogger.warn(text: string, data: object): void
: Log a warning with message and data to consolelogger.error(text: string, err: object): void
: Log a message and an error to consolenew FriendlyErrorsWebpackPlugin({ verbose: boolean, onSuccessMessage: string, target: 'web' | 'server' })
This will pretty print webpack errors to your console. It is mean to be used with Razzle's double webpack setup, where you have two webpack instances running in parallel. Otherwise the output looks almost identical to create-react-app's
as it uses the same error formatter under the hood.
const FriendlyErrorsPlugin = require('razzle-dev-utils/FriendlyErrorsPlugin');
module.exports = {
// ...
plugins: [
new FriendlyErrorsPlugin({
verbose: false,
target: 'web',
onSuccessMessage: `Your application is running at http://${process.env.HOST}:${process.env.PORT}`,
}),
// ...
],
// ...
}
printErrors(summary: string, errors: Error[])
Pretty print an array of errors with a message. Good for CI's.
const printErrors = require('razzle-dev-utils/printErrors');
try {
// do something
} catch (e) {
printErrors('Failed to compile.', [e]);
}
makeLoaderFinder(loaderName: string): (rule: WebPackRule) => boolean;
Helper function to find a loader in the webpack config object. Used for writing Razzle Plugins, or razzle modify functions.
Example:
// razzle.config.js
const loaderFinder = require('razzle-dev-utils/makeLoaderFinder');
module.exports = {
modify(config) {
// Makes a finder function, to search for babel-loader
const babelLoaderFinder = makeLoaderFinder('babel-loader');
// Finds the JS rule containing babel-loader using our function
const jsRule = config.module.rules.find(babelLoaderFinder);
// Set cacheDirectory to true in our babel-loader
jsRule.use.find(babelLoaderFinder).options.cacheDirectory = true;
},
};
