Next JS config 多插件配置

Question

const {
  DEVELOPMENT_SERVER,
  PRODUCTION_BUILD
} = require("next/constants");

require('dotenv').config()

const path = require('path')
const Dotenv = require('dotenv-webpack')

const nextConfig = {
  webpack: config => ({ ...config, node: { fs: "empty" } })
};
module.exports = phase => {
  if (phase === DEVELOPMENT_SERVER || phase === PRODUCTION_BUILD) {
    const withCSS = require("@zeit/next-css");
    return withCSS(nextConfig);
  }
  return nextConfig;
};
*module.exports =  {
  webpack: (config) => {
    config.plugins = config.plugins || []
    config.plugins = [
      ...config.plugins,
      // Read the .env file
      new Dotenv({
        path: path.join(__dirname, '.env'),
        systemvars: true
      })
    ]
    return config
  }
}*

let prefix;
switch (process.env.NODE_ENV) {
  case "test":
    prefix = "https://test.domain.com/providers";
    break;
  case "stage":
    prefix = "https://state.domain.com/providers";
    break;
  case "production":
    prefix = "https://production.domain.com/providers";
    break;
  default:
    prefix = "";
    break;
}
module.exports = {
  distDir: "build",
  assetPrefix: prefix
};

这是我的 next.config.js 配置。但是当我尝试运行时，会收到类似错误的消息！网络错误：JSON 中的意外标记 N 在位置 0

但是，当我尝试将任何内容运行到粗体（*）中并仅将其保留到 next.config.js 中时，就可以正常工作了。如何在module.export中配置多个插件

Answer 1

这是在 Next.js 中使用多个嵌套插件的简单方法

const withImages = require('next-images');
const withCSS = require('@zeit/next-css');

module.exports = withCSS(withImages({
    webpack(config, options) {
      return config
    }
  }))

如果您想使用单个插件，请执行以下操作：

const withImages = require('next-images');

module.export = withImages();

next-compose-plugins plugin 提供了一个更清晰的 API，用于为 next.js 启用和配置插件。

安装 npm install --save next-compose-plugins

在next.config.js：

// next.config.js
const withPlugins = require('next-compose-plugins');
const images = require('next-images');
const sass = require('@zeit/next-sass');
const typescript = require('@zeit/next-typescript');

// optional next.js configuration
const nextConfig = {
  useFileSystemPublicRoutes: false,
  distDir: 'build',
};

module.exports = withPlugins([

  // add a plugin with specific configuration
  [sass, {
    cssModules: true,
    cssLoaderOptions: {
      localIdentName: '[local]___[hash:base64:5]',
    },
  }],

  // add a plugin without a configuration
  images,

  // another plugin with a configuration
  [typescript, {
    typescriptLoaderOptions: {
      transpileOnly: false,
    },
  }],

], nextConfig);
