ES Resolve
JavaScript/TypeScript module resolution in Rust
Installation
cargo add es_resolve
Get Started
use std::path::{Path, PathBuf};
use es_resolve::*;
// Provide an exact path to the file from which we resolve
let source = PathBuf::from("tests/fixtures/relative/js.js");
// Construct an `es_resolve::EsResolver`, then call `resolve` to get the result.
// Also check `es_resolve::EsResolverError` for a list of errors that might occur!
let target = EsResolver::new("./ts", &source, TargetEnv::Browser).resolve().unwrap();
let expected_target_path = Path::new("tests/fixtures/relative/ts.ts").canonicalize().unwrap();
let expected_target = expected_target_path.to_string_lossy();
// We expect to get the absolute path to the resolved target module!
assert_eq!(target, expected_target);
