      }],
    ],
  },
};

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	@swc/core@1.3.58 ~ next@v13.4.3-canary.2 ~

If this table becomes outdated, it is recommended to check the compatibility by referring to the upstream's Selecting the version article.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.

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