Crate rspack 

Rspack is a high performance JavaScript bundler written in Rust. It offers strong compatibility with the webpack ecosystem, allowing for seamless replacement of webpack, and provides lightning fast build.

For guide level documentation, please refer to the Rspack Guide.

Example

Rspack uses tokio as the runtime for async operations. Here’s an example of how to use with Compiler:

[dependencies]
tokio = { version = "1", features = ["full"] }
rspack = "0.3"
rspack_core = "0.3"

use std::path::PathBuf;

use rspack::builder::{Builder, CompilerBuilder};
use rspack_core::Compiler;

#[tokio::main]
async fn main() {
  use rspack_tasks::within_compiler_context_for_testing_sync;
  within_compiler_context_for_testing_sync(|| {
    let context =
      PathBuf::from(env!("CARGO_MANIFEST_DIR").to_string()).join("tests/fixtures/basic");
    let compiler = Compiler::builder()
      .context(context)
      .entry("main", "./src/index.js")
      .build()
      .unwrap();

    let errors: Vec<_> = compiler.compilation.get_errors().collect();
    assert!(errors.is_empty());
  })
}
