  experimental: {
    swcPlugins: [
      ['@lingui/swc-plugin', {
       // the same options as in .swcrc
      }],
    ],
  },
};

module.exports = nextConfig;

Note Consult with full working example for NextJS in the /examples folder in this repo.

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.

| Plugin Version | used swc_core | Compatibility | |------------------------------------------|-----------------|------------------------------------------------------------------------------------------------------| | 0.1.0, 4.0.0-next.0 | 0.52.8 | [email protected] ~ [email protected] | | 0.2.*, 4.0.0-next.1 ~ 4.0.0-next.3 | 0.56.1 | @swc/[email protected] ~ @swc/[email protected] [email protected] ~ [email protected] | | 4.0.0 | 0.75.33 | @swc/[email protected] ~ @swc/[email protected] [email protected] ~ [email protected] | | 4.0.1 | 0.76.0 | broken due to lto = true | | 4.0.2 | 0.76.41 | @swc/[email protected] ~ @swc/[email protected] [email protected] ~ | | 4.0.3 | 0.78.28 | @swc/[email protected] ~ @swc/[email protected] [email protected] ~ [email protected] | | 4.0.4 | 0.79.x | @swc/[email protected] ~ @swc/[email protected] [email protected] ~ | | 4.0.5 | 0.87.x | broken due incorrect version of swc_common | | 4.0.6 | 0.87.x | @swc/[email protected] ~ @swc/[email protected] ~ [email protected] | | 4.0.7 | 0.90.35 | @swc/[email protected] ~ [email protected] ~ @rspack/[email protected] ~ |

This table may become outdated. If you don't see a particular version of @swc/core or next check the compatibility by referring to the upstream's Selecting the version article. This will help you select the appropriate plugin version for your project.

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.*
