NextJS Starter

This is the starter front-end app using NextJS for VideoAmp. It supports TypeScript for JS and Stylus with Styled-JSX for CSS.

Check out Next.js repo for the most up-to-date info.

Out of the box, we get:

• Automatic transpilation and bundling (with webpack and babel)
• Hot code reloading
• Server rendering and indexing of ./pages
• Static file serving. ./static/ is mapped to /static/

Getting Started

Check the available scripts.

Note: The starter app is behind an authentication portal that will need to be loaded. Clone this repo to get going: https://github.com/VideoAmp/launchpad.

You can log in via these credentials:

U: [email protected]
P: supreme100!

You will also need to create a .env file in your root path of the repo. Add these lines to your .env file:

DEV_APP_DOMAIN=http://localhost:3001
STAGING_APP_DOMAIN=https://linear-planner.videoamp.com
PROD_APP_DOMAIN=

Folder Structure

The app is scaffolded like this:

my-app/
  README.md
  package.json
  next.config.js
  routes.ts
  server.ts
  ...
  components/
    /Head
        index.ts
        Head.tsx
    /Nav
        index.ts
        Nav.tsx
  pages/
    index.js
    page1/
        index.tsx
        index.styles.tsx
  static/
    favicon.ico

Routing

File System Routing

Note: This is disabled by default for VideoAmp Apps, but can be re-enabled by removing

useFileSystemPublicRoutes: false,

from the next.config.js file.

File system routing is based on the file system, so ./pages/index.tsx maps to the / route and ./pages/about.js would map to /about.

The ./static directory maps to /static in the next server, so you can put all your other static resources like images or compiled CSS in there.

Programmatic Routing

If you want dynamic URLs and named parameters, you can do add them in the routes.ts file that's located in the root folder

Example route: /initiatives/123/plans/456/plan /initiatives/123/plans/456 is also valid do the the ? at the end of this RegEx :type(plan|daypart)?. Both routes will load from the /pages/initiatives/plans/index.tsx file

routes.ts

const routes = module.exports = require('next-routes')()

routes.add({ name: 'plans', pattern: '/initiatives/:id/plans/:slug/:type(plan|daypart)?', page: 'initiatives/plans' })

Available Scripts

In the project directory, you can run:

yarn dev

Runs the app in the development mode. Open http://localhost:3001 to view it in the browser.

The page will reload if you make edits. You will also see any errors in the console.

yarn build

Builds the app for production to the .next folder. It correctly bundles React in production mode and optimizes the build for the best performance.

yarn start

Starts the application in production mode. The application should be compiled with `next build` first.

See the section in Next docs about deployment for more information.

Using CSS

styled-jsx with Stylus support is bundled with next to provide support for isolated scoped CSS. We enforce that your CSS be written as an external file and imported. Read more here.

index.styles.tsx

import css from 'styled-jsx/css'

export const cardStyles = css`
    .card {
        width: 640px;
        min-height: 450px;
        background-color: #000000;
        display: block;
        margin: 1em auto;
        padding: 1em;
        
        header {
            background-color: #FF0000;
        }
    }
`;

Component.tsx

import { cardStyles } from "./index.styles";
...
render(){
    return (
        <div className="card">
            <header>Header</header>
                <Button
                    onClick={() => ())}
                    primary
                    raised
                > 
                    I'm a button
                </Button>
            <style jsx>{cardStyles}</style>
        </div>
    )
}

Adding Components

We recommend keeping React components in ./components and they should look like:

./components/Simple/simple.tsx

interface SimpleProps {
    text: string,
}

export const Simple = (props: HeadProps) => (
    <div>{props.text || ""}</div>
)

./components/Complex/complex.tsx

import { Component } from "react";

interface ComplexProps {
    text?: string,
}

export class Complex extends Component<ComplexProps> {
  state = {
    text: 'World'
  }

  render () {
    const { text } = this.state
    return <div>Hello {text}</div>
  }
}

Fetching Data

You can fetch data in pages components using getInitialProps like this:

./pages/stars.tsx

import axios from "axios";

interface StarProps {
    stars: number;
}

const Stars: NextReact.SFC<StarProps> = ({stars} ) => {
    return <div>{stars}</div>
}

Stars.getInitialProps = async ({ req }) => {
    const { data } = await axios.get('https://api.github.com/repos/zeit/next.js')
    return { stars: data.stargazers_count }
}

Stars.defaultProps = {
  stars: 0
};

export default Stars

For the initial page load, getInitialProps will execute on the server only. getInitialProps will only be executed on the client when navigating to a different route via the Link component or using the routing APIs.

Note: getInitialProps can not be used in children components. Only in pages.
