  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	next@13.0.0 ~ next@13.2.3
0.2.*, 4.0.0-next.1 ~ 4.0.0-next.3	0.56.1	@swc/core@1.3.29 ~ @swc/core@1.3.37 next@13.2.4-canary.0 ~ next@13.2.5-canary.5
4.0.0	0.75.33	@swc/core@1.3.49 ~ @swc/core@1.3.57 next@v13.3.1-canary.12 ~ next@v13.4.3-canary.1
4.0.1	0.76.0	broken due to lto = true
4.0.2	0.76.41	@swc/core@1.3.58 ~ @swc/core@1.3.62 next@v13.4.3-canary.2 ~
4.0.3	0.78.28	@swc/core@1.3.63 ~ @swc/core@1.3.67 next@v13.4.8 ~ next@v13.4.10-canary.0
4.0.4	0.79.x	@swc/core@1.3.68 ~ @swc/core@1.3.80 next@v13.4.10-canary.1 ~
4.0.5	0.87.x	broken due incorrect version of swc_common
4.0.6	0.87.x	@swc/core@1.3.81 ~ @swc/core@1.3.105 ~ next@v14.1.0
4.0.7	0.90.35	@swc/core@1.4.0 ~ next@14.1.1-canary.52 ~ @rspack/core@0.6.0 ~

This table may become outdated.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.*
