@conduitvc/build

Conduit presets for React and Node.js

@conduitvc/build lets you develop, build, and lint React and Node.js applications with Neutrino-based presets for external tooling.

Setup

In your project, install the necessary development dependencies:

# If you are building a React application, also add webpack-dev-server
yarn add --dev webpack webpack-cli neutrino@next eslint @conduitvc/build

Next, add a .neutrinorc.js file to the root of the project with the following minimal boilerplate, adding or removing middleware pieces as needed for the particular project. The setup for each available middleware is outlined below.

module.exports = {
  options: {
    root: __dirname,
  },
  use: [
    // Use available presets here
  ],
};

webpack + React

At a minimum, you need to be able to build and start the React application. Add the react middleware to the .neutrinorc.js use array:

module.exports = {
  options: {
    root: __dirname,
  },
  use: [
    ['@conduitvc/build/react', {
      flow: true, // Optionally enable flow syntax
      typescript: true, // Optionally enable typescript syntax
      html: {
        title: 'Project Title',
      },
    }],
  ],
};

Most middleware allow you to specify an array pair of middleware package and its options. Above we set the default page title, and any more options that can be passed relate to the options accepted by @neutrinojs/react.

Next, create a webpack.config.js file in the root of the project with the following code to ensure that Neutrino loads the necessary middleware and sends it off to webpack:

const neutrino = require('neutrino');

module.exports = neutrino().webpack();

You can now start webpack and webpack-dev-server using normal mechanisms, writing the React application in a src directory.

webpack + Node.js

At a minimum, you need to be able to build and start the Node.js application. Add the node middleware to the .neutrinorc.js use array:

module.exports = {
  options: {
    root: __dirname,
  },
  use: [
    ['@conduitvc/build/node', {
      flow: true, // Optionally enable flow syntax
      typescript: true, // Optionally enable typescript syntax
    }],
  ],
};

Most middleware allow you to specify an array pair of middleware package and its options. More options that can be passed relate to the options accepted by @neutrinojs/node.

Next, create a webpack.config.js file in the root of the project with the following code to ensure that Neutrino loads the necessary middleware and sends it off to webpack:

const neutrino = require('neutrino');

module.exports = neutrino().webpack();

You can now start webpack using normal mechanisms, writing the Node.js application in a src directory.

ESLint

To have runtime and build-time linting with ESLint using Conduit rules, add the relevant Airbnb middleware as the first entry in the .neutrinorc.js use array.

Note: Use airbnb for React projects, and airbnb-base for Node.js projects.

React .neutrinorc.js

module.exports = {
  options: {
    root: __dirname,
  },
  use: [
    '@conduitvc/build/airbnb',
    ['@conduitvc/build/react', {
      // ...
    }],
  ],
};

Node.js .neutrinorc.js

module.exports = {
  options: {
    root: __dirname,
  },
  use: [
    '@conduitvc/build/airbnb-base',
    ['@conduitvc/build/node', {
      // ...
    }],
  ],
};

---

Next, create a .eslintrc.js file in the root of the project with the following code to ensure that Neutrino loads the necessary middleware and sends it off to ESLint:

const neutrino = require('neutrino');

module.exports = neutrino().eslintrc();

You can now start webpack, webpack-dev-server, or ESLint using normal mechanisms, with linting errors and warnings. The following is the recommended ESLint command to use for one-off lint checks:

eslint --cache --format codeframe src

If you need to override any ESLint rules or settings, pass an array pair with options according to the @neutrinojs/eslint, @neutrinojs/airbnb, or @neutrinojs/airbnb-base docs.

module.exports = {
  // ...
  use: [
    ['@conduitvc/build/airbnb', {
      eslint: {
        baseConfig: {
          rules: {
            semi: 'error',
          },
        },
      },
    }],
    // ...
  ],
};
