Pre-release v1.0.0-rc.6

Changes:

• Supports import attributes, in particular TypeScript's resolution-mode assertion.

Fixes:

• Assign correct outDir in all use cases.

Pre-release v1.0.0-rc.5

Changes:

• Stops deleting the build output directory defined by outDir before builds, and instead does a copy overwrite to the specified outDir, or dist if no outDir defined.

Pre-release v1.0.0-rc.4

Changes:

• Use dist as a default outDir when one is not defined.
• rm the outDir prior to build.
• Add some timing around preparing parallel builds.
• Update README.

Pre-release v1.0.0-rc.3

Changes:

• Adds --parallel option to run the builds in parallel.
• Updates the README.

Pre-release v1.0.0-rc.2

• Adds --dirs option.
• Updates dependency babel-dual-package.
• Updates README.

BREAKING CHANGE:

• Renames the dual build dir for CJS-first projects from mjs to esm. Update your project's exports before publishing after building with duel.

Once this package hits a stable 1.0.0 release there will be no breaking changes without changing the major version.

Pre-release v1.0.0-rc.1

BREAKING CHANGE:

• Deprecates --target-extension in favor of --pkg-dir to infer the dual build target from the package.json type field. Deprecates as in completely removes support. These are pre-releases after all.

Changes:

• Adds --pkg-dir to indicate what directory to start looking for a package.json file. Defaults to the cwd. You should rarely, if ever need this.
• Updates the documentation (README).
• Builds should be slightly faster now that no copying of files is necessary post build since duel now uses --module nodenext in combination with dynamic package.json files.

Initial release candidate, v1.0.0-rc.0

Changes:

• No substantial changes from the last release. Updates the README and ensures correct runtime behavior of the build output on Node.js starting from a CJS-first project.

Pre-release v1.0.0-alpha.4

Changes:

• Allows a peerDependency on typescript 4.
• Ensures the correct module system by file extension for each build, despite the difficulties in trying to do this with tsc alone.

Pre-release v1.0.0-alpha.3

Changes:

• Add more test assertions to a successful build.
• Update README.
• Improve spacing in --help output.

Pre-release v1.0.0-alpha.2

Changes:

• Expands the README.
• Removes unused dependency magic-string.
