Object type#

tools.swc can be configured as an object, this object will be deeply merged with the built-in builtin:swc-loader option.

export default {  tools: {  swc: {  jsc: {  externalHelpers: false,  },  },  }, };

Function type#

tools.swc can also be configured as a function, this function takes one argument, which is the built-in builtin:swc-loader option. You can modify this object then return a new config. For example:

export default {  tools: {  swc: (config) => {  config.jsc ||= {};  config.jsc.externalHelpers = false;  return config;  },  }, };
