a tsickle webpack loader (for using ADVANCED closure compiler optimizations)
@appmonet/tsickle-loader
This is a webpack loader for tsickle; it lets us compile typescript code with the typescript
compilaer, while adding annotations & externs readable by closure compiler, which means we can use ADVANCED_OPTIMIZATIONS
mode. See the test
directory for an example of compiling this way.
usage
You can use this like any normal webpack loader; it takes a some options:
module.exports = {
module: {
rules: [
{
// you use tsickle-loader in place of typescript-loader;
// it will compile for you using typescript
test: /\.ts$/,
use: {
loader: "tsickle-loader",
options: {
// the tsconfig file to use during compilation
tsconfig: path.resolve(__dirname, "tsconfig.json"),
// this is the directory where externs will be saved. You
// will probably want to delete these between builds
externDir: "./tmp/externs"
}
}
}
]
}
};
