Babel

The program does not provide the corresponding parameter configuration, you can only modify the configuration of Babel in the form of a plug-in.

Write a Babel plugin

import { Plugin, BabelConfig } from '@fmfe/genesis-core';

export class BabelPlugin extends Plugin {
    public babel(config: BabelConfig) {
        // config.presets
        // config.plugins
        // Modified example
        config.presets.forEach((preset) => {
            if (Array.isArray(preset) && preset[0] === '@babel/preset-env') {
                // Modify babel preset-env configuration
            }
        });
    }
}

genesis.dev.ts and genesis.build.ts use this plugin

ssr.plugin.use(BabelPlugin);
