Working with URL encoded form values

Tue, 19 Sep 2023 00:00:00 +0000

In the book, we discussed how to send and received multipart form data. That is, forms containing both text fields and file uploads, typically using the content type as multipart/form-data. When we are working with only text fields, it is sufficient to instead use the content type, application/x-www-form-urlencoded and send the data as a URL encoded set of key value pairs. For example, as described by the MDN article, say=Hi&to=Rheo will be the request payload for a form with two text fields, say and to with the values, Hi and Rheo respectively.

Using SQLite from Go

Thu, 29 Jun 2023 00:00:00 +0000

In the book, we used MySQL server as a way to store relational data from our applications. In this post, we will see how to use work with SQLite from Go.

The demo code used is available in this repository.

The table names and operations are intentionally chosen to losely match that of the official Go Project tutorial, Accessing a relational database which uses MySQL as the database server.

Let’s get started!

I write my blog posts in Markdown format, and then use Hugo static site generator to generate HTML files. The topic of this blog post is how those HTML files are served to you.

If you happened to come across my GopherCon 2021 lightning talk, this blog post describes the topic in all the gory detail!

Hello world

Hello everyone. “Practical Go: Building Scalable Network and Non-Network Applications” is now out electronically as well as in print.

The book targets readers who have learned the Go language basics - syntax, understanding of types, being able to write functions (details are available in the “Getting started” chapter - but essentially, just a passing familiarity with the language is enough I think). I say that and reasonably confidently since that’s where I was when I started writing this book. I wrote this book, not to share with you things I already knew - far from it. The book is essentially a documentation of my journey of learning Go and applying it to solve problems which I think based on my experience are being solved by folks in the industry a.k.a real world today.
