Babel Plugin: ESM Resolver

A Babel plugin for resolving ESM import and export paths

Overview

Resolves ESM import and export paths to other source modules with extensions, optionally replacing the extension with a different one (including imports with extensions, like native ESM and Deno-style TypeScript). This is useful because most environments will not perform automatic file extension resolution.

Since it resolves the statements before the modules are transpiled, it can also be used to resolve the paths for other transpiled module loaders.

Must be configured to work properly, it will not do anything by default.

There are three classes of resolver that can be enabled (source, module, submodule) depending on the modules that need to be resolved. Module support for ESM has improved so only source is likely to be needed.

Usage

Options

source Source modules: import foo from './bar'
module Module main entry points: import foo from 'bar'
submodule Module submodules: import foo from 'bar/foo'

NOTE: The module and submodule options are generally no longer needed now that conditional exports are available.
