"All you need is the standard library" - Everyone on the internet
I can't tell you the number of times I heard this when learning to create web applications using Go. After a while, it started to haunt me.
I started learning Go by reading the standard library and every tutorial I could find, but I quickly ran into a problem.
Rather than creating HTML templates and rendering real dynamic content, we were instead using fmt.Fprint() to print hard coded HTML. 😱
Or when we needed access to a database we would create a global connection and share it with ALL of our code. Yikes!
As a result, I couldn't figure out how to get past creating my first few pages. It was frustrating, to say the least.
While getting stuck I kept asking myself questions like...
- "How do I share my database connection with my handlers?"
- "How do I hash user passwords securely? What is the correct way to make sure a user is authenticated and has access to this resource?"
- "How should I organize my code? Where does the MVC pattern fit into all of this? Is my design RESTful? Will it be hard to maintain?"
No matter how many tutorials I read, I always felt like there was something left out. Some part of the bigger picture that wasn't explained, leaving me unsure of how to proceed.
The underlying problem was that every single tutorial I read oversimplified things, and what I needed was a comprehensive course showing me how all the pieces worked together.
Web applications are complex systems
After building my umpteenth silly TODO app, single page wiki, or some other contrived example I nearly gave up.
My progress was painfully slow, and every time I solved one problem I found myself facing two new ones. I still had no idea how to connect all of the pieces together.
It was as if someone had handed me toolbox, taught me how to use each tool, and then said "You now know how to build a house!" The hell I do! My house would blow over within the week if that was how construction worked.
It isn't enough to simply learn how each tool works. Knowing how to use a tablesaw, nailgun, and power drill don't qualify me to construct a house. You need to learn how every piece of a house gets connected together first. How the roof connects to the frame, how the frame is supported by the foundation, how much space to leave for air vents in the frame, and countless other details. In short, you need to know how everythign works together.
So why do we keep thinking this approach will work for web development? Why do we keep telling new Gophers, "All you need is the standard library to build web applications!"
Technically it isn't inaccurate, but it sure as hell isn't the ideal way to learn and it leads to developers slugging through countless tutorials, reading endless docs, and trying hundreds of bad approaches before they finally get it right. And even then they aren't confident what they did is right. They just know it hasn't failed yet.
But what if you didn't have to struggle through hundreds of tutorials?
What if you didn't have to read countless tutorials? What if you didn't have to guess at how to hash and store a user's password? What if you had confidence that your authentication was truly secure? You would finally be able to rest easy at night knowing you aren't letting your users down. Or you would be able to start actually building that app so you can meet your first customers. And most importantly, you could finally start enjoying the benefits of using Go for web development.
Web Development with Go can help you cut through all the complexity and finally become the developer you know you should be.
Web development with Go absolutely saved me from giving up on Go. Before finding this course I kept hitting roadblock after roadblock. I can't tell you how excited I was when I realized just how approachable and productive this course is. I went from struggling to get even the most basic tasks completed to actually building out my own app idea. I can't wait to release it!
Web Development with Go is the course I wish I had.
This course is the result of over a year of work and research. Time spent reading documentation, source code, blog posts, and anything else I could get my hands on. Writing thousands of lines of code, refactoring endlessly, and constantly seeking better design patterns.
Web Development with Go will save you months of research, trial and error, and nights scratching your head. After completing the course you will...
- ‣ Know exactly how to initialize your database connection and give the rest of your code access to it
- ‣ Have clear examples of how and when to email users.
- ‣ Be positive that you are salting and hashing your passwords correctly
- ‣ Feel confident saying, "Yes, my authentication system is safe and secure!"
- ‣ Know exactly how to organize your code using MVC so that it encourages a RESTful design.
- ‣ And so much more!
All of this is possible because this is not your run of the mill 30 minute tutorial. It is a comprehensive breakdown of every aspect of web development, teaching everything from how to create the most basic web application all the way to preparing your code and deploying it in a production environment. The course spans over 38 hours of screencasts and the included ebook is over 700 pages long. Even after completing the course, you will be referencing the material for years to come.
(Watch a sample screencast of the first web application we write. Be sure to check out the followup video where we explain what all of this code does afterwards.)

Don't just take my word for it
The course is already being used by hundreds of others who absolutely love it. Some were even so excited that they had to share it with the world. Here is a taste a few of them had to say...
Jon does a great job of taking the large task of creating a web application and breaks it down into steps that are easy to understand and follow along with. If you want to learn how web development works at its very core I can't recommend it enough.
I learned of Jon Calhoun's course via the Gopher Slack. His contributions and advice to the "greenhorns" of Golang alone was enough to capture my attention. Jon was clearly prepared while writing "Web Development With Go". It is well organized, far from biased, and demonstrates best practices in the process.
The course takes the form of an in-depth tutorial and forces the reader to follow along and get their hands dirty. It covers everything from submitting a form, to normalizing data before persisting it on the backend. Whether you are a Go developer or not, you will certainly learn something new from this book.
Amigo. Your course KICKS ASS! Your code is clear, your delivery is clear, and I just did a few of the algorithm tutorials on your site and they too are clearly explained. Thank you!!!
Great JOB!
Todd was the teacher that I and many others needed to learn the basics of Go.
Jon is the teacher that I and others need now to learn web development. He made the effort to make web development easy to understand and I respect him for that.
Jon's course, Web Development with Go, is amazing. It is filled with a great insights and has been an amazing resource of knowledge.
Invest in yourself by buying this book along with the extras. You won’t regret it.
What you will learn
Here are just a few of the things we will be covering in this course. Everything is taught in the context of our final web application, but we will occasionally review a topic in isolation before looking at how it connects to the rest of our application.
-
How to build a web application from scratch
While following along with the book, you will learn how to build everything from the most basic web server and continuously build upon it until you have a fully fledged web application.
-
What are MVC and REST?
You will learn all about MVC (model-view-controller) and REST including how using both design principles can make your application significantly easier to maintain and improve as you are learning. Once you understand MVC you will be in a great place to start learning about more advanced design techniques (like domain driven design).
-
How to create and utilize templates
Static pages are boring, so we will use the
html/templatepackage included in Go's standard library to create HTML pages with dynamic content. This will allow us to display custom dashboards, galleries, and images for each user depending on what page they visit and what they have access to. -
How to build an authentication system
Web Development with Go will teach you how to build a proper authentication system including how to hash passwords with bcrypt, creating user sessions, avoiding timing attacks, and so much more.
If you aren't 100% certain your authentication system is secure, this is a must-read!
-
How to interact with a PostgreSQL database
Not only will you learn how to create, update, and delete records using the
database/sqlpackage, but we will also cover how to normalize and validate data before saving it to your database. We even cover how to relay validation errors to your end users. -
How to process file uploads
Our photo galleries need images, so we will write all of the code necessary to accept file uploads, process those incoming images, and finally serve them back to end users who visit our galleries.
-
How to send emails to users
No matter how smart your users are, some of them are bound to forget their pssword. We will cover how to utilize services like Mailgun to send emails to our customers when this happens, giving them a way to restore access to their account.
-
How to use the Dropbox API
If you purchase a package with the bonus content you will also learn how to interact with the Dropbox API, including implementing oauth2 to get access to a user's Dropbox folders and importing images from a user-specified directory to create a photo gallery.
-
Plus many more topics
This is only a small subset of all the things we will learn. Check out what you will build or read the Chapter List to get a better idea of everything we cover, and if you have any questions don't hesitate to email me if you are curious about a specific topic.
What you will build
Throughout the course you will be building LensLocked, a website where photographers can create photo galleries to share with their clients.
Photographers can sign up, create galleries, and upload photos all from within their dashboard.
After a gallery is completed it can be published, making it publicly accessibly to anyone with the URL and allowing photographers to share their work with their clients.
If you purchase one of the packages with bonus content we will also look at how to let photographers link their Dropbox account and import galleries directly from Dropbox folders, allowing them to skip the annoying task of uploading photos that are already in their Dropbox account.
Samples & Chapter List
Web Development with Go will teach you how to build web applications by guiding you through the process of creating a photo gallery application. The course is broken down into the following chapters. Each chapter varies in length depending on how much material is covered and how many new concepts are being introduced, but they average around 45 pages per chapter in the ebooks, and around 2 hours of screencasts per chapter.
- 1 - Introduction (sample chapter)
- 2 - A Basic Web Application (sample chapter)
- 3 - Adding New Pages (sample chapter)
- 4 - A Brief Introduction to Templates
- 5 - Understanding MVC
- 6 - Creating Our First Views
- 7 - Creating a Sign Up Page
- 8 - An Introduction to Databases
- 9 - Creating the User Model
- 10 - Building an Authentication System
- 11 - Remembering Users
- 12 - Normalizing and Validating Data
- 13 - Displaying Errors to the End User
- 14 - Creating the Gallery Resource
- 15 - Adding Images to Galleries
- 16 - Preparing for and Deploying to Production
- 17 - Filling in the gaps (emailing users, resetting passwords, etc)
Bonus Content
Order "The Complete Package" or "The Book + Bonus Content" package and you will receive the following bonus content where we use OAuth and the Dropbox API in our app.
- 18 - Authorizing Dropbox Accounts with the Dropbox API
- 19 - Importing Images via the Dropbox API*
- 20 - Creating Galleries with Dropbox Folders*
* The bonus content (Ch18-20) currently covers how to use OAuth2 with Dropbox, and how to use the Dropbox Chooser to import images and create galleries, but I plan to add more videos covering how to build our own custom chooser implementation over time.
Get a FREE Sample
Interested in checking out a sample of the course to see if it is a good fit for you? No problem! Just let me know where to send it and I will send over a course preview that includes over 2 hours of screencasts and the first 3 chapters of the book in PDF, Kindle, epub, or HTML format.
But I'm new to programming!
So what?!? While this book will provide a ton of value to veteran developers, it was designed to be accessible for beginners.
Every chapter goes over everything we introduce in great detail, making sure you aren't felt lost. You will frequently find "aside" videos that go into more detail about a topic, but are easily skipped if you are already familiar with the topic.
Below is an example of this, where I break down what a web request is and show examples of each component using the web developer tools available in Google Chrome.
The only expectations I make in the book are that you are vaguely familiar with Go and are willing to learn. That's it, and even the vaguely familiar with Go part could be fixed in a few days if you are really motivated.
When I introduce new techniques (like variadic parameters) or touch on any other advanced topic I take a moment to explain what we are doing so that you won't get lost.
On top of all the content in the course, there is also a shared slack where you can chat with myself and many others who are working through the course to get feedback and advice.
And finally, I also have a FREE course - Gophercises - that you can use to level up your Go programming skills, so trust me when I say there are plenty of resources to help get you up to speed 😃

Matt Holt Securing your Server
Matt is the creator of Caddy Server, an HTTP/2 web server with automatic HTTPS. It is incredibly awesome, and even if you don't buy this course you should check it out.

Michael Hartl
Learning Just Enough
Michael is the creator of Rails Tutorial and Learn Enough where he creates material teaching Web Development and more.
Michael and I spend our time discussing how you beginners fall into the trap of trying to learn everything, but all they really need to learn is "enough to be dangerous." That is, just enough to get the job done, and then you can slowly build upon your skill set as the need arises. Not only is this approach much more rewarding (you get to see things ship faster!), it also drives you to learn the skills you need most and not waste time learning things you won't use.

Charlie Guo
Doing the Unscalable
Charlie is the author of Unscalable, a book that covers the lesser-known backstories of many startups in Silicon Valley and how they did unscalable things in order to succeed.
In our interview Charlie and I discuss how nearly every business was built by doing something unscalable. Whether it was manual data entry, going door-to-door to get feedback from customers, or running a business from a spreadsheet, everyone has their ugly backstory.
Charlie and I then discuss how web applications are often built the same way. You can't possibly build every feature, so you pick and choose which things you must have and do the rest manually or fake it.

Ryan Jackson
Starting a Tech Company
Ryan is a 2 time Y Combinator founder and is currently working at his startup Paid.

‣ How do I find my first customer?
‣ When can I start charging?
‣ Is my pricing right?
After that we discuss how the internet has enabled businesses like his to iterate quickly and adapt as customers provide feedback, making it possible to adjust when you get things like your pricing wrong.

Adam Wathan
Testing and More
Adam is the creator of a Test-Driven Laravel, the creator of Nitpick CI, and the host of Full Stack Radio.

After that the conversation moves on to consulting, and some simple tips that can make it much easier to find out what a client needs built. Finally we move into the subject of testing, discussing how Adam goes about deciding what to test and writing tests that aren't tightly coupled to his implementation.

The Team Package
Have a team you want to purchase copies of the course for? No problem! I offer team packages for companies of all sizes. Simply send me an email at jon@calhoun.io with a little more information and I'll share the details with you.
Why does this cost so much?
Unfortunately this course doesn't cost $10. I know, I know, many courses on Udemy go on sale every month. Why isn't this one of those courses?
For starters, charging more enables me to provide extremely awesome help to my students. Just ask anyone who has taken the course - if they have any issues at all I will jump through hoops to help them out. This simply isn't possible with a $10 course, and I don't believe that you should be left to the wolves if you can't figure something out on your own.
In addition to enabling awesome support, this course is also jam packed with valuable information. The screencasts are over 38 hours long, but I suspect you will spend at least 80 hours completing the actual course if you are coding along and trying to absorb everything. In that time you will learn what took me and many other "do-it-yourselfers" countless hours and many sleepless nights to learn. You get to take the shortcut while I hold your hand and teach this all to you in an easy to follow format.
And finally, this course is built to last. I want you to reference this for years to come. That means I will need to update the course over time, and a cheap price tag isn't conducive to that. The current pricing is, and as a result you will continue to see this course maintained over the years.
So no, the course isn't cheap, but I promise you it is worth every penny. And just in case, I also offer a 100% money back guarantee.
Note: For context, most online courses are 4-10 hours of screencasts. That means this course covers ~4x more content than most other online courses, and it means you will understand what you are doing that much better when you complete the course. Is saving a few bucks worth being stuck for weeks or months after completing another course?
About the Author
Hi! My name is Jon Calhoun. I create courses and other education content about Go, programming, and anything else I find interesting.
You have probably seen some of my work before:
▹ Gophercises - a FREE course with mini (1-2hr) Go exercises
▹ Web Development with Go - a premium course that teaches how to build real web apps in go (~38hrs of video)
▹ Calhoun.io - my blog where I publish articles, tutorials, and some screencasts on Go, PostgreSQL, or algorithm related topics
I also gave a talk at Gotham Go (2018), spoke on the Go Time podcast, founded EasyPost, and worked at Google before all of that.

Questions?
-
What formats do you support?
The book is available in PDF, ePub, Mobi, and HTML.
The screencasts and video interviews are hosted on Vimeo for streaming in various qualities and I also provide links to download each video as an mp4 so that you can download and watch whenever you want. No DRM or other BS. I trust you 🙂
-
Can I get a sample?
You betcha! Fill out this form and I will send you a sample with the first three chapters and over 2 hours of screencasts.
-
Which package should I buy?
That really depends. The complete package is obviously the best, and if you work as a professional developer or plan to I definitely suggest that package. You will be referencing it for years to come, and there are some gems hidden in the screencasts that are just impossible to convey in text.
If you are concerned about the price, the other two packages provide a ton of value and you won't regret purchasing either of them. And you can always upgrade later if you want.
-
Do you offer a student discount?
Yep! Just shoot me an email - jon@calhoun.io - requesting more info.
-
What if I hate it?
Ouch! Well, if you really feel that way I don't want your money. Just send me an email with your receipt and I'll issue you a refund. It is that simple.
-
Will there be updates to the material?
YES! I plan to review and update the course frequently to keep it up to date and keeping the code in sync with what I feel is the best way the material should be taught.
-
When will unfinished content be released?
The bonus content, Chapters 18-20, are recorded and released but are only spread out across two chapters. I plan to split the material up and potentially add some extra videos over time, but the actual content is fully covered in the released videos.
-
You didn't answer my question...
Email me and I'll do my best to answer your questions. Or if you prefer phone, just let me know how and when to reach you and I'll give you a call.
What are you waiting for?
Don't waste another minute struggling to figure everything out. Pick a package that meets your needs and start learning web development with Go!

-
Source Code
Get access to all of the source code used in the book from start to finish. You can easily jump to the code before/after a specific chapter, making it easy to jump to a specific section of the book or double check your work.
Bonus Chapters
You will receive 3 bonus chapters covering how to integrate with the Dropbox API via OAuth, allowing your users to connect their Dropbox account, select a folder on their Dropbox account, and import the images in that folder as a gallery.

The Book
The least expensive option (but still great)!
While the screencasts, video interviews, and everything else are incredibly valuable, the book itself shouldn't be overlooked. It is where I spent the most time and effort and laid the groundwork for everything else. You will be referring to the best practices in this book for years to come.
If your budget is preventing you from purchasing the bonus content and screencasts, I highly recommend this package. You won't regret it.
