The Ultimate 2800+ Words Guide to Deploying Frontend Apps on Netlify

My friend, welcome to this comprehensive guide on deploying and hosting frontend web applications on Netlify!

I‘m thrilled to walk you through this entire journey over the next 25 minutes. Buckle up! 🚀

The Dramatic Evolution of Frontend Deployment

Remember the days when deploying something as simple as a portfolio website felt like a complex ordeal? Setting up servers, configuring databases, security protocols – things we totally took for granted in the backend-driven past.

But over the last decade, the frontend ecosystem has evolved at lightning speed:

  • Powerful JavaScript frameworks like React, Vue and Angular emerged.
  • New approaches like the JAMstack prioritized frontend technologies.
  • Developer experience and workflows dramatically improved.
  • Deployment platforms arrived that required zero backend code.

And leading this revolution in frontend deployment and hosting is Netlify.

Why Netlify is Your Best Bet for Frontend Hosting

Netlify has essentially solved frontend deployment complexity for us. As a platform, it offers some amazing benefits:

Blistering fast global CDN that delivers your sites and assets to your users at warp speed.

Intuitive Git-based workflows that trigger automated builds and deployments when you push code.

Support for all modern web frameworks like React, Vue, Svelte, Next.js and more.

Custom domains, SSL certificates, and intelligent routing rules are all pre-configured.

Community support, tutorials, and docs to solve any problems you face.

And these barely scratch the surface of Netlify‘s capabilities! We‘ll discover much more over the course of this guide.

Excited? Let‘s get started!

Prerequisites Before You Deploy

I want to ensure you have all the prerequisites sorted before we actually dive into Netlify deployments. Let‘s go through them one-by-one:

Step 1 – Create a Netlify Account

Head to netlify.com, click on Sign Up, and create a new account.

You can log in with your GitHub or GitLab account to skip filling additional details.

Step 2 – Understanding Git Basics

Our frontend app‘s code needs to be tracked on Git before pushing it to GitHub or GitLab repositories that Netlify can access.

So if you haven‘t already, install Git on your machine and learn some basic commands:

git init
git add .
git commit -m "My first commit" 

Tip: Here is a great Git tutorial to understand workflows.

Step 3 – Developing the Frontend App

For this guide, I have built simple React and plain JavaScript apps. But you can use Vue, Angular or any other library for building the app you want to deploy.

Ensure your app runs fine locally before proceeding.

Alright, now we are all set with the prerequisites!

Deployment Method #1 – Using Your GitHub Repository

If your frontend app code is already tracked on GitHub, it‘s incredibly easy to deploy from there.

Let me walk you through it:

Step 1 – Push Code to GitHub

Initialize a git repo locally and push your code to GitHub:

git init
git add . 
git commit - m "Initial commit"

git remote add origin https://github.com/<your_username>/frontend-app
git push -u origin master

This shares your app‘s code on the frontend-app GitHub repo.

Step 2 – Connect GitHub and Netlify

Head to Netlify and click on New Site from Git. Choose GitHub from the list of providers.

Next, authorize access by logging into your GitHub account when prompted.

Under the Repository Access section, grant access to only the specific frontend-app repo. Hit Save.

Step 3 – Trigger Your First Deploy!

You‘ll now be able to search and select the frontend-app repo within Netlify.

Pick your branch, then click on Deploy Site to trigger your first deploy! 🎉

Under a minute later, your frontend app will be live on Netlify‘s global CDN! Crazy fast.

And that‘s all there is to it! Isn‘t that easy?

Going further, any git push to your GitHub repo will automatically rebuild and deploy changes. I‘ll talk more about that later.

First, let me show you another deployment method…

Deployment Method #2 – Using Netlify CLI

Netlify also offers a command line interface (CLI) for deployment from your local terminal.

While the GitHub method from earlier is perfect for already tracked projects, the CLI approach lets you deploy local sites as well.

Here is how it works:

Step 1 – Install Netlify CLI Globally

Run this command on your terminal to install Netlify CLI:

npm install netlify-cli -g

The -g flag makes the CLI command accessible globally.

Tip: You may need to use sudo before this command on Linux/Mac.

Step 2 – Login and Link Your Site

Fire up the CLI, log into your Netlify account, and link up the local site folder:

netlify login  

netlify init

The CLI opens up a browser window for logging into your account after the login command.

Step 3 – Straight Up Deploy!

While still in your site‘s root directory, run the deploy command:

netlify deploy

Just like that, Netlify starts building and deploying your site!

It even assigns you a temporary draft URL you can preview. Once ready, you can deploy to production by running:

netlify deploy --prod  

And that wraps up the second deployment method!

Additional Configuration and Customization

Now that we have successfully deployed our frontend app through two different methods, let‘s look at customizing our deployments further.

Netlify offers a ton of configuration options inside Site Settings > Build & Deploy once your site is live.

Custom Domains

The first thing I would set up is adding a custom domain along with the free SSL that Netlify provisions:

Environment Variables

Sensitive keys and other dynamic configuration should be set up as environment variables:

Setting up environment variables on Netlify

These get injected during builds without exposing them publicly.

Similarly, you can customize build settings, post-processing scripts, headers, and more granularly based on production or branch deployments.

Check the Netlify build settings docs for details.

Optimizing Your Deployed Site

To ensure blazing fast performance for your live site, Netlify applies basic optimizations by default.

But here are some additional front-end performance techniques you should implement:

Bundling and Minification – Combine files and compress assets by integrating tools like Webpack into your build process.

Code Splitting – Separate code into asynchronous chunks to reduce initial loads.

Image Compression – Apply conversion and compression methods for smaller image file sizes.

Caching Strategies – Set far-future expiration for assets to leverage caching benefits.

HTTP/2 Server Push – Proactively push critical assets for faster page loads.

Optimizing app performance requires a few key mindset shifts. I‘ve written an in-depth guide on Frontend Optimization Strategies if you want to dive deeper.

For now, audit your Netlify site using online tools and continuously improve loading metrics over time.

Continuous Deployment Superpowers

Earlier I briefly mentioned that Netlify automatically rebuilds your site for every code commit you push to your Git repository.

Let‘s talk more about that – along with a powerful feature called Deploy Previews.

Effortless CI/CD Pipelines

The Continuous Deployment flow looks like this:

You commit new code changes and push them to your GitHub repo ➜ Netlify detects these changes thanks to the earlier connected hook ➜ Triggers a new build and deployment automatically!

I love how entire CI/CD pipelines are abstracted away as Git workflows with Netlify. No need to set up external tools whatsoever.

This helps accelerate the dev process incredibly as you can deploy often without any overhead.

Previewing Every Pull Request

Netlify can also generate a temporary staging URL to preview changes corresponding to every pull request before they are merged.

These are called Deploy Previews:

The benefit? You and your team can validate the impact of incoming code changes without directly affecting production. No more nervous waits hoping the master deploy succeeds after a PR merge!

I encourage you to explore other features like Split Testing, Serverless Functions and Authentication that provide advanced capabilities on top of core platform offering as well.

Troubleshooting Deployment Failures

My friend, so far we‘ve had smooth sailing understanding how to deploy sites using Netlify.

But real-world deploys involve occasional hiccups and failures. Let‘s prepare ourselves to tackle them!

Common issues can arise from – build errors, incompatible environment variables or dependencies, external API failures and more.

Thankfully, Netlify provides multiple tools to diagnose deployment failures:

Deployment Logs – Logs that capture your entire site build with helpful error messages.

Local Simulation – Replicate issues accurately by deploying locally via Netlify CLI.

Support Team – Netlify‘s legendary support staff helps resolve even rare issues.

Forums + Docs – Learn from Q&As posted by 100,000+ fellow developers.

Getting comfortable debugging problems and learning to avoid common mistakes will help you significantly as your apps grow more complex.

So don‘t worry about the occasional failed deploy – leverage support channels to fix them and learn quickly as you progress.
