Deploy Go Application in ubuntu





golang has faciltity of cross compilation. So you can write a your application on any of supported  platform and deploy it over any supported platform. So will go step by step from compilation to deployment of the project over ubuntu server ( linux server )

Requirements

1. Linux Server

I mostly use ubuntu but this also work with CentOs

2. FTP/sFTP Upload Tool 

For windows I will recommand winScp Download
For Mac I personlly use ftp uploader provided by the mozzila as firefox addon Download


3. SSH Tool

For windows i will recommand putty  Download
For Mac I personally use FireSSH  Download

Thats it.



Compile the project for the linux


(I am using the windows for this tutorial , but for mac the links are show where neccessary)

Run this command to compile the project

Set GOOS for cross Compilation (windows )












> set GOOS=linux 

upper command will set the golang host architecture to linux
( this is temporary change so after reboot it will set the original host. GOOS defines the platform/ architactre for which the code will build)

> go build
This is the normal build command you use to generate the build of application
( you can also use the go install command. in that case your binary will generate in the bin folder, but for cross complation build command is recommaned by the golang team)



Upload the necessary files using the FTP/sFTP tool 


Here nessarry files means the assets files and the binary of your project
Upload files using the winscp


Use SSH client 


replace add with your binary name

$ chmod u+x app 


Running the application in background 
Run the application using SSH client
$ ./app
(here one problem is that as soon as you close your ssh client application will be terminated so use the step show below )

To make application running in background and make sure that it will not killed by hup run this command
$./app & > nohup.out

Hope you find it helpfull

Firebase - update a spacific fields of single element of object of array in firestore

Firebase - update a spacific fields of single element of object of array in firestore  Its actully advisable to use map instead of array when ever it is possible. But, there are cetain cases where you don't have option to do so.  For example, you are directly saving the response from some outer source without any modification and they send you an array. In this case you will have array to work with. Firestore does not support array here is why  "bad things can happen if you have multiple clients all trying to update or delete array elements at specific indexes. In the past, Cloud Firestore addressed these issues by limiting what you can do with arrays " For more details information you can refer to Kato Richardson post Best Practices: Arrays in Firebase .  Firestore document having array [ used from stackoverflow question ] Suppose you have array of object something like shown in array. Now you want to update endTime field of the object on the index [1]

Sciter : GUI Application with Golang using HTML/CSS

GUI library for golang sciter This is the words from Sciter's Web site, Sciter brings a stack of web technologies to desktop UI development. Web designers and developers can reuse their experience and expertise in creating modern looking desktop applications. Various GUI frameworks offer different UI declaration and styling languages, such as QML and  XAML (Microsoft WPF) . On the contrary, Sciter allows using time proven, robust, and flexible HTML and CSS for GUI definition and GPU accelerated rendering.   Before using sciter I already tried other alternatives but none of them was satisfactory as an example first i tried andlabs / ui  library   i already have written a post on it. You can read it on post gui programming with golang .  But this library is still under construction and has no support for production apps. Secondly, I go for electron but the problem was my simple calc like the app was of size 150mb. Which is 15mb of go and other was the e
