Method to Build Fast Applications with Golang Development Services?
In recent years Golang has gained a lot of interest amongst the mobile app developer community owing to its type safety, easy refactoring, speed and easy deployment capabilities. We bring to you some interesting information about how you can go about building fast applications with Golang with this blog.
- An Introduction about Go
An open source language, Go was built by hackers from Google who did not take much to the interface and working of C++. Go doesn’t have the features of OOPS such as inheritance or encapsulation nor does it have the complexity of any object-oriented language. This language has been designed keeping in mind an easy to use interface which can be utilized by all developers for building simple applications at a rapid pace. While developing an application with Go language, you need to know a few sets of commands and features and bam… you are ready to begin!
- Multi-Git Repositories
A multi git allows you to make changes to multiple code sources at once and this is an important tool at your disposal when you are looking for rapid development. If you have your code team working on a single code segment and they happen to be coding from different location, multi-git comes in handy. A multi git program will allow you to modify data in each of these different repositories used by developers from various locations simultaneously without the need to make changes across each repository individually.
- Package and Imports
Every application you build in Go will have a set of packages which work together to carry out the functionality of the application. There is a single main.go file which is similar to the main in C++, executed first followed by the other connected packages. You can get the required package and or import the same from sources available online using the ‘Go’ and ‘Get’ command available.
- Command Line Arguments
A command line argument is how you provide an input to any application built in Go. These arguments provide the requisite inputs for the application you wish to run with a single line of code. These command line arguments are parsed according to the flag packages which are imported as the main procedure begins execution.
- Environment Variables
One other way to configure any application or program in Go is by using the environment variables. Using these variables, you can run a single application or code snippet multiple times using the same set of arguments. Two main environment variables used in this language are “MG_Root” and “MG_REPOS”. A multi git program runs and manages multiple repositories and controls the same through MG_Root variable and the names and value of repositories will be stored in the ‘MG_REPOS” variable and these are used to configure applications.
- Verification of Repositories
Now that we’ve discussed about running an application and controlling the input arguments and setting up environment variables, the next step is to ensure that every repository is attached to the main package. To do so, a list is traversed and the repository address is concatenated in front of the directory address, however in case of mismatch the same fails and an error is reported. As you can see, building an application with go and running it is pretty simple!
Being fairly easy to code, GO is the preferred language for many mobile app and web application developers. In fact, it is easy to build scalable app engines too with GO; do give it a try and watch our blog space for more such blogs on GO, ROR and RMAD.
Thus, Golang development services is best platform to make fast application.
