What can I learn from this project?

You will learn how to structure your project and build many internal and external API infrastructures.

On the browser, the main technologies you will learn are: Next.js, React.js, Material-UI.
On the server, the main technologies you will learn are: Next.js, Node.js, Express.js, Mongoose.js, MongoDB database.

In addition to the above technologies, you can learn how to integrate your web application with the following external API services:

Plus, you can learn many concepts such as session and cookie, headers, HTTP request-response, Express middleware, Promise, async/await, and more. You have to know these concepts to be a confident web developer, no matter what language you use.

The main use cases for this project, besides learning, are:

  • To write and host free documentation with Github being a source of truth for content.
  • To sell online content, such as books.
  • To extend it (see our second book, SaaS Boilerplate Book) to start software business.

Creating a Google OAuth Client

This guide will walk you through the steps to create a Google OAuth client for your application.

Prerequisites

Before you begin, make sure you have the following:

  1. Sign in to Google Cloud Console:
  • Go to the Google Cloud Console.
  • Sign in with your Google account or create one if you don’t have it.
  1. Create a New Project:
  • Click on the project dropdown in the top navigation bar.
  • Click on “New Project.”
  • Give your project a name and click “Create.”
  1. Enable the Google+ API (if required):
  • If you plan to use Google+ Sign-In for authentication, enable the “Google+ API” for your project.
  • In the Cloud Console, go to the API & Services > Library.
  • Search for “Google+ API” and enable it.
  1. Create OAuth Client ID:
  • In the Cloud Console, navigate to the API & Services > Credentials page.
  • Click on “Create Credentials” and then select “OAuth client ID.”
  • Select the application type, typically “Web application” for a website or web application.
  • Fill out the necessary information, such as the name of the OAuth client and authorized redirect URIs (where Google should redirect the user after authentication). You can use http://localhost as a redirect URI for development.
  • Click “Create” to generate your OAuth client credentials. It will provide you with a client ID and client secret.

Creating a GitHub Client ID and Client Secret

To create a GitHub Client ID and Client Secret, follow these steps:

  1. Sign in to your GitHub Account:
    If you don’t have a GitHub account, create one.

  2. Go to Developer Settings:
    Click on your profile picture in the top right corner of GitHub and select “Settings.” In the left sidebar, under “Developer settings,” click on “OAuth Apps.”

  3. Create a New OAuth App:
    Click on the “Register a new application” button.

  4. Fill in the Application Details:
    You’ll be prompted to fill in details about your application:

    • Application Name: The name of your application.
    • Homepage URL: The URL to your application’s website.
    • Application Description: A brief description of your application.
    • Authorization callback URL: This is the URL to which GitHub will redirect users after they authorize your application. For testing purposes, you can use http://localhost if you’re developing locally.

  5. Generate Your Client ID and Client Secret:
    After you’ve filled in the details, click the “Register application” button. GitHub will generate a Client ID and Client Secret for your application.

Run locally

  • Clone the project and run yarn to add packages.

  • Before you start the app, create a .env file at the app’s root. This file must have values for some env variables specified below.

  • To use all features and third-party integrations (such as Stripe, Google OAuth, Mailchimp), create a .env file and add values for all variables as shown below. These variables are also listed in .env.example, which you can use as a template to create your own .env file.

.env :

# Used in server/server.js
MONGO_URL=
MONGO_URL_TEST=
SESSION_SECRET=

# Used in lib/getRootUrl.js
NEXT_PUBLIC_URL_APP=
NEXT_PUBLIC_PRODUCTION_URL_APP="https://heroku.builderbook.org"

MAILCHIMP_SIGNEDUP_LIST_ID=

# Used in pages/_document.js and pages/_app.js
NEXT_PUBLIC_GA_MEASUREMENT_ID=
COOKIE_DOMAIN=".builderbook.org"

  • IMPORTANT: do not publish your actual values for environmentable variables in .env.example; this file is public and only meant to show you how your .env file should look.

  • Add your value (domain that you own) for COOKIE_DOMAIN and NEXT_PUBLIC_PRODUCTION_URL_APP.

  • Start the app with yarn dev.

    • To get NEXT_PUBLIC_GA_MEASUREMENT_ID, set up Google Analytics and follow these instructions to find your tracking ID.
    • To get Stripe-related API keys, set up or log into your Stripe account and find your key here.

  • Env keys NEXT_PUBLIC_GA_MEASUREMENT_ID and NEXT_PUBLIC_STRIPE_TEST_PUBLISHABLEKEY/NEXT_PUBLIC_STRIPE_LIVE_PUBLISHABLEKEY are universally available (client and server). Env keys inside .env file are used in server code only unless they have NEXT_PUBLIC_ prepended to their name. In that case, they are universally available.

  • To make user a book’s owner, set "isAdmin": true on corresponding MongoDB document in your database (default value is false for any new user).

Important: if you don’t add values for environmental variables to .env file, corresponding functionality will not work. For example, login with Google account, purchasing book, getting repo information via GitHub API and other third-party API infrastructures.

Add a new book

  • Create a new Github repo (public or private).

  • In that repo, create an introduction.md file and write some content.

  • At the top of your introduction.md file, add metadata in the format shown below. See this file as an example.

    ---
title: Introduction
seoTitle: title for search engines
seoDescription: description for search engines
isFree: true
---

  • Go to the app, click “Connect Github”.

  • Click “Add Book”. Enter details and select the Github repo you created.

  • Click “Save”.

When you add new .md files or update content, go to the BookDetail page of your app and click Sync with Github.

Important: All .md files in your Github repo must have metadata in the format shown above.

Important: All .md files in your Github repo must have name introduction.md or chapter-N.md.

To make the content of a .md file private (meaning a person must purchase the content to see it), remove isFree:true and add excerpt:"". Add some excerpt content - this content is public and serves as a free preview.

Add your own styles

To change the color scheme of this app, modify the primary and secondary theme colors inside lib/context.js. Select any colors from Material UI’s official color palette.

Recommended ways to add your own styles to this app:

  1. Inline style for a single element
  2. Reusable style for multiple elements within single page or component
  3. Reusable/importable style for multiple pages or components
  4. Global style for all pages in application

Inline style for a single element

USE CASE: apply a style to one element on a single page/component

For example, in our book page, we wrote this single inline style:

<p style={{ textAlign: 'center' }}>
  ...
</p>

See usage

Reusable style for multiple elements within single page or component

USE CASE: apply the same style to multiple elements on a single page/component.

For example, in our tutorials page, we created styleExcerpt and applied it to a <p> element within the page:

const styleExcerpt = {
  margin: '0px 20px',
  opacity: '0.75',
  fontSize: '13px',
};

<p style={styleExcerpt}>
  ...
</p>

See usage

Reusable/importable style for multiple pages or components

USE CASE: apply the same style to elements on multiple pages/components.

For example, we created styleH1 inside components/SharedStyles.js and exported the style at the bottom of the file:

const styleH1 = {
  textAlign: 'center',
  fontWeight: '400',
  lineHeight: '45px',
};

module.exports = {
  styleH1,
};

See usage

We then imported styleH1 into our book page, as well as our index page, and applied the style to a <h1> element:

import {
  styleH1,
} from '../components/SharedStyles';

<h1 style={styleH1}>
  ...
</h1>

See usage

Global style for all pages in application

USE CASE: apply the same style to elements on all pages of your app.

Create your style in pages/_document.js. For example, we specified a style for all hyperlinks that use the <a> element:

<style>
  {`
    a, a:focus {
      font-weight: 400;
      color: #1565C0;
      text-decoration: none;
      outline: none
    }
  `}
</style>

Deploy to Heroku

In this section, we will learn how to deploy our app to Heroku cloud. We will deploy our React-Next-Express app to lightweight Heroku container called dyno.

Instructions are for app located at /book/8-end.
Adjust route if you are deploying app from the root of this public repo.

We will discuss the following topics in this section:

  1. installing Heroku on Linux-based OS
  2. creating app on Heroku dashboard
  3. preparing app for deployment
  4. configuring env variables
  5. deploying app
  6. checking logs
  7. adding custom domain

Let’s go step by step.

  1. Install Heroku CLI (command-line interface) on your OS. Follow the official guide. In this book we provide instructions for Linux-based systems, in particular, a Ubuntu OS. For Ubuntu OS, run in your terminal:
sudo snap install --classic heroku

To confirm a successful installation, run:

heroku --version

As example, my output that confirms successful installation, looks like:

heroku/7.22.7 linux-x64 node-v11.10.1

  1. Sign up for Heroku, go to your Heroku dashboard and click purple New button on the right:


    image

    On the next screen, give a name to your app and select a region. Click purple Create app button at the bottom:


    image

    You will be redirected to Deploy tab of your newly created Heroku app:


    image

  2. As you can see from the above screenshot, you have two options. You can deploy the app directly from your local machine using Heroku CLI or directly from GitHub.
    In this tutorial, we will deploy a async-labs/builderbook/book/8-end app from our public async-labs/builderbook repo hosted on GitHub. Deploying from a private repo will be a similar process.

    Deploying from GitHub has a few advantages. Heroku uses git to track changes in a codebase. It’s possible to deploy app from the local machine using Heroku CLI, however you have to create a Git repo for async-labs/builderbook/book/8-end with package.json file at the root level. A first advantage is that we can deploy from a non-root folder using GitHub instead of Heroku CLI.

    A second advantage is automation, later on you can create a branch that automatically deploy every new commit to Heroku. For example, we have a deploy branch for our demo for SaaS boilerplate. When we commit to master branch - there is no new deployment, when we commit to deploy branch - new change is automatically deployed to Heroku app.

    Let’s set up deploying from GitHub. On Deploy tab of your Heroku app at Heroku dashboard, click Connect to GitHub, then search for your repo, then click Connect next to the name of the proper repo:


    image

    If successful, you will see green text Connected and be offered to select a branch and deploy app automatically or manually. Automatic deployment will deploy every new commit, manual deployment requires you to manually click on Deploy Branch button. For simplicity, we will deploy manually from master branch of our async-labs/builderbook repo.

    Before we perform a manual deployment via GitHub, we need Heroku to run some additional code while app is being deploying. Firstly, we need to tell Heroku that 8-end app in the async-labs/builderbook repo is not at the root level, it’s actually nested at /book/8-end. Secondly, Heroku needs to know that our app is Node.js app so Heroku finds package.json file, properly installs dependencies and runs proper scripts (such as build and start scripts from package.json). To achieve this, we need to add so called buildpacks to our Heroku app. Click Settings tab, scroll to Buildpacks section and click purple Add buildpack button:


    image

    Add two buildpacks, first is https://github.com/timanovsky/subdir-heroku-buildpack and second is heroku/nodejs:


    image

    Next, scroll up while on Settings tab and click purple Reveal Config Vars button, create a new environmental variable PROJECT_PATH with value book/8-end:


    image

    The above variable will be used by the first buildpack subdir-heroku-buildpack to deploy app from repo’s subdirectory.

  3. If we deploy app at this point, our app will deploy with errors since we did not add environmental variables. Similar to how you added PROJECT_PATH variable, add all environmental variables from book/8-end/.env file to your Heroku app. Remember to add the rest of env variables for all features to work, including signup event.

  4. While on Settings tab, scroll to Domains and certificates section and note your app’s URL. My app’s URL is: https://builderbook-8-end.herokuapp.com
    Let’s deploy, go to Deploy tab, scroll to Manual deploy section and click Deploy branch button.
    After deployment process is complete , navigate to your app’s URL:


    image

  5. Server logs are not available on Heroku dashboard. To see logs, you have to use Heroku CLI.
    In your terminal, run:

    heroku login

    Follow instructions to log in to Heroku CLI.

    After successful login, terminal will print:

    Logged in as [email protected]

    Where [email protected] is an email address that you used to create your Heroku account.

    To see logs, in your terminal run:

    heroku logs --app builderbook-8-end --tail

    In your terminal, you will see your most recent logs and be able to see a real-time logs.

    You can output certain number of lines (N) for retrieved logs by adding --num N to the heroku logs command.
    You can print only app’s logs by adding --source app or system’s logs by adding --source heroku.

  6. Time to add a custom domain. The Heroku app that we created is deployed on free dyno. Free dyno plan does not let you to add a custom domain to your app. To add custom domain, go to Resources tab and click purple Change Dyno Type button:


    image

    Select a Hobby plan and click Save button.

    Navigate to Settings tab and scroll to the Domains and certificates and click purple Add domain button:


    image

    Type your custom domain name, I added heroku.builderbook.org as a custom domain, click Save changes button.

    Heroku will display you a value for CNAME record that you have to create for your custom domain. For me, custom domain is heroku.builderbook.org and I manage DNS records at Now by Zeit.

    After you create a CNAME, ACM status on Heroku’s dashboard will change to Ok:


    image

It’s important that you remember to manually add your custom domain to the settings of your Google OAuth app (Chapter 3) and GitHub OAuth app (Chapter 6). If you forget to do it, you will see errors when you try to log in to your app or when you try to connect GitHub to your app.

Scaling

You may want to consider splitting single Next/Express server into two servers:

  • Next server for serving pages, server-side caching, sitemap and robots
  • Express server for internal and external APIs

Here is an example of a web application with split servers:
https://github.com/async-labs/saas

Splitting servers will get you:

  • faster page loads since Next rendering does not block internal and external APIs,
  • faster code reload times during development,
  • faster deployment and more flexible scaling of individual apps.
