    // HTML string that will be placed after other styles in the head.
    style: String,
  
    // HTML string that will be placed before other scripts in the end
    // of the body, useful for providing SSRed stores, for example
    // Redux or Apollo stores.
    script: String
  }

Environment Variables

Environmental variables can be used to override options that were set in jepa.options.js during startup time. You can place a .env file in src/ folder.

The following variables are currently supported:

• process.env.HOST
• process.env.PORT

jepa.config.js

• webpackModify (AsyncFunction): A function that takes an object argument of shape {webpackConfig, target: 'web' || 'node', env: 'dev' || 'prod'}, and should return a webpack config object.
• postcss (Object): postcss-loader options.

Runtime Dependencies

By default both client and server are bundled with Webpack, which means there is no use of node_modules during runtime. Most of the time this works perfectly fine however there are cases when certain dependencies can't be bundled (usually these are native dependencies).

You can create a package.json file and optionally package-lock.json or yarn.lock files and specify dependencies there that shouldn't be bundled with Webpack and installed to node_modules.
