In our previous Golang tutorial, we have explained how to create REST API in Golang. In this tutorial, we will explain how to work with regular expressions in Golang.
A regular expression or regex is a sequence of characters to define a search pattern. It’a powerful technique used in most of programming language. Instead of writing many code lines, regex provides fast solution to handle everything in a single line of code to search, replace, extract, pattern matching etc. (more…)
In our previous tutorial, we have explained how to Delete Files in Golang. In this tutorial, we will explain how to create REST API in Golang.
REST (Representational State Transfer) is the most used interface to populate the dynamic data and perform operations such as add, update and delete in web applications. The REST APIs are used in all kinds applications to make GET, POST, PUT or DELETE HTTP requests to perform CRUD operations on data.
In this tutorial, we are going to explain to create simple REST API with Golang to perform GET, POST, DELETE and PUT on dynamic data. We will mainly focus on the basic concepts of this, so we will perform actions on employee JSON data instead of database. So you can use this by connection with database as per your application requirement. (more…)
The Geolocation is identification of an object in a geographic location. It includes information related to latitude, longitude, address, country code, country, zip code and more.
Geolocation data is useful for businesses to know about customers to target with relevant information. Due to importance, the businesses always looking for geolocation data of their customers. It’s not an easy task to get the accurate geolocation data, but thanks to the IPWHOIS.IO Geolocation API which provide the accurate geolocation solution.
IPWHOIS.IO provide fast and accurate gelocation data from across the world. The API is very easy to integrate and deliver results in JSON, XML or Newline format. It is totally free for up to 10,000 requests per month. IPWHOIS.IO API is used by thousands of developers all around the world. (more…)
In our previous tutorial, we have explained how to Read File Line by Line in Golang. In this tutorial, we will explain how to Delete Files in Golang.
While working with files and directories, sometimes we need to delete specific file or all files from a directory. It’s very easy in Golang to delete a file. There are a Remove() and RemoveAll() method from os package in Golang to delete the files from a directory. (more…)
In our previous tutorial, we have explained to work with Date and Time in Golang. In this tutorial, we will explain how to work with Structs in Golang.
Structs in Golang is a ability to create user-defined data type from group of data fields with different data types. The data field in a struct can be declared with built-in or user-defined data types.
The concept of struct can be compared with the object-oriented programming which supports composition but not inheritance. (more…)
In our previous tutorial, we have explained How to Make HTTP Requests in Golang. In this tutorial, we will explain how to work with Date and Time in Golang.
Date and Time is a common functionality in web applications to display dates in different formats according to requirement. Sometimes we need to get current timestamp or sometimes need to convert timestamp into human readable date time format. In Golang, we can use Time package to handle date time functionality. (more…)
