v3.35.0

Compare Source

• Upgrade glob to fix a security vulnerability in the inflight package. ([#​822]) (Patrick Nappa)
  • Note that the sucrase CLI no longer works in Node.js versions before 14.7.
    • If you use the sucrase CLI, you should pin to Sucrase 3.34.0 until you're able to upgrade
      Node.js to a supported version. Note that all Node.js versions before 18 are end-of-life.
    • If you don't use the sucrase CLI, you may need to silence errors related to package.json
      engines, e.g. yarn --ignore-engines.
  • This change is being released in a semver-minor release since it fixes a security vulnerability
    and the breaking change impact is expected to be small. See this PR comment
    for a rationale on the release strategy.

v3.34.0

Compare Source

• Add CLI options for all remaining Sucrase options, e.g. --disable-es-transforms for
  disableESTransforms. (<<-ArS, Alan Pierce) ([#​670], [#​812])
• Add SUCRASE_OPTIONS environment variable for configuring sucrase/register, sucrase-node,
  and any programmatic require hook usages. The value must be a valid JSON object of Sucrase
  options that will be merged with the usual options. ([#​813])

v3.33.0

Compare Source

• Add an option keepUnusedImports that disables all automatic import/export
  elision, equivalent to the TypeScript option verbatimModuleSyntax. ([#​811], [#​615]) (Kotaro Chikuba, Alan Pierce)
• Add support for the await using proposal and the updated import attributes proposal.
  Both are preserved in the output code, not transformed. ([#​798])
• Fix some issues with TypeScript automatic export elision in export {...} from statements. ([#​806])
  • Type names from the current file are no longer removed.
  • When all exports are type exports, the entire statement is now removed.
• Fix bug where fn(x < y, x >= y) was incorrectly parsed as type arguments. ([#​798])
• Fix a few bugs in enableLegacyBabel5ModuleInterop: properly handle as default, and properly ignore type exports. ([#​804], [#​807]) (三咲智子 Kevin Deng, Alan Pierce)
• Fix bug where parameters inside function types could be misinterpreted as declarations and result in imports being incorrectly marked as unused. ([#​809])
• Fix bug where import {} and export {} statements were removed with the TypeScript transform disabled. ([#​810])
• Make the transform behavior more forgiving when code accidentally has a return type annotation on a constructor. ([#​800])
