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…)
In our previous tutorial, we have explained about Channels in Golang. In this tutorial, we will explain how to make HTTP Requests in Golang.
There are net/http package is available to make HTTP requests. We just need tp import the package in our script and can use GET, POST, PostForm HTTP functions to make requests.
So here in this tutorial we will explain how to make GET, POST, PostForm HTTP requests in Golang. (more…)
In our previous tutorial, we have explained how to achieve Concurrency with Goroutines in Golang. In this tutorial, we will explain about Channels in Golang and how Goroutines communicate with Channels.
Channels are the pipes that used with Goroutines for sending and receiving values. We can send the values with Channels from one Goroutines and can receive those values in another Goroutines. (more…)
In our previous tutorial, we have explained how to work with Maps in Golang. In this tutorial, we will explain about Goroutines in Golang. Goroutines are functions in Golang that are run concurrently which means multiple operations can be handled at the same time. It’s about creating and executing multiple processes independently.
With Goroutines, we can easily convert sequential programs into concurrent program without having to worry about thread pools as the Golang creates very light-weight threads that’s managed by Go runtime. (more…)
In our previous tutorial, we have explained how to handle Marshalling and Unmarshalling in Golang. In this tutorial, we will explain about Maps in Golang. Map in Golang is a data structure that provides an unordered collection of keys/values pairs. Golang maps are same like associative arrays, hash or dictionaries in other programming languages.
The maps are used to store and access values based on key. A key works like an index, pointing to the value associate with that key. A map data structure is used for fast lookup, retrieval and deletion of the data based on keys. (more…)
In this tutorial, we will explain how to encode and decode data in Golang. Data encoding is an important part of any programming language to encode data into JSON or decode data into String.
In Golang, struct data is converted into JSON and JSON data to string with Marshal() and Unmarshal() method. The methods returned data in byte format and we need to change returned data into JSON or String.
In our previous tutorial, we have explained about Parsing JSON Data in Golang. In this tutorial, we will explain about data marshal and unmarshal in Golang. (more…)
