Selecting swc_core

Selecting the version

Currently, the Wasm plugins are not backwards compatible. So you need to select an appropriate version of swc_core for your plugin.

We provide a simple webapp to help you select the version of swc_core.

See: https://plugins.swc.rs (opens in a new tab)

You can select the framework and the version of framework you are using, and the Wasm plugins compatible with it will be shown.

OLD Documentation for the version of swc_core

Please use the webapp instead.

The page documents the version of swc_core you can use for each runtime.

Note for next.js

swc_core

If you use a version in a range of the title, the Wasm plugin will work for the runtimes written in the body.

v0.98.x ~

Changes

  • Span.ctxt is removed to reduce the size of Span.
  • ctxt: SyntaxContext is added to various AST nodes.
  • IdentName is used instead of Ident in some places like MemberProp, because those fields does not need ctxt or optional.
