React ts-loader Not Working with Babel Loader Webpack
If you are working with TypeScript and React, you might have encountered an issue where the ts-loader
is not working properly with the babel-loader
in Webpack. This can be frustrating, but don’t worry, we have some solutions for you!
Solution 1: Use the babel-loader
before the ts-loader
One solution to this problem is to configure the Webpack loaders in such a way that the babel-loader
runs before the ts-loader
. This allows Babel to transpile the TypeScript code before passing it to the TypeScript loader.
module.exports = {
module: {
rules: [
{
test: /.(tsx|ts)$/,
exclude: /node_modules/,
use: [
{
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env', '@babel/preset-react']
}
},
{
loader: 'ts-loader'
}
]
}
]
}
};
This configuration tells Webpack to first use the babel-loader
with the specified presets, and then pass the transpiled code to the ts-loader
.
Solution 2: Use the babel-loader
with the ts-loader
Another solution is to use the babel-loader
together with the ts-loader
. This can be achieved by configuring the ts-loader
to use Babel for transpiling the TypeScript code.
module.exports = {
module: {
rules: [
{
test: /.(tsx|ts)$/,
exclude: /node_modules/,
use: [
{
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env', '@babel/preset-react']
}
},
{
loader: 'ts-loader',
options: {
transpileOnly: true,
getCustomTransformers: () => ({
before: [require('babel-plugin-transform-typescript-metadata').default]
})
}
}
]
}
]
}
};
In this configuration, we are using the transpileOnly
option to tell the ts-loader
to only transpile the code without performing type checking. We also provide a custom transformer to handle TypeScript metadata using the babel-plugin-transform-typescript-metadata
.
Final Thoughts
These are two possible solutions to the issue of react ts-loader
not working with babel-loader
in Webpack. Depending on your specific use case and requirements, you can choose the solution that works best for you.
Remember to always check the official documentation of the loaders and plugins you are using for the most up-to-date information and configuration options.
Happy coding!
