Compatibility

SWC Plugin support is still experimental. They do not guarantee a semver backwards compatibility between different swc-core versions.

So you need to select an appropriate version of the plugin to match compatible swc_core using a https://plugins.swc.rs/.

Note next v13.2.4 ~ v13.3.1 cannot execute SWC Wasm plugins, due to a bug of next-swc.

next v13.4.3 ~ v13.4.5-canary.7 cannot execute SWC Wasm plugins, due to missing filesystem cache.

• Version 0.1.0 ~ 0.* compatible with @lingui/core@3.*
• Version 4.* compatible with @lingui/core@4.*
• Version 5.* compatible with @lingui/core@5.*
