Level up your git commit messages

What is a commit message?

In short, a git commit records changes to a repository.

Why a good commit message?

How to write a good commit message?

  • One commit for one “logical change”
  • Include module/feature name enclosed in [ ]
  • Followed by a type of commit
  • Followed by a meaningful and descriptive message
  • Do include Jira bug id if the commit is fixing an issue
  • Do include ticket id if it’s a new feature

Example:

Types of commit messages:

build: Changes that affect the build system or external dependencies

ci: Changes to CI configuration files and scripts

docs: Documentation only changes

feature: A new feature

fix: A bug fix

perf: A code change that improves performance

refactor: A code change that neither fixes a bug nor adds a feature

style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)

test: Adding missing tests or correcting existing tests

Things to avoid when creating commits:

  • Mixing two unrelated functional changes.
  • Sending large new features in a single giant commit.

It may well be the case that the code for a new feature is only useful when all of it is present. This does not, however, imply that the entire feature should be provided in a single commit. New features often entail refactoring existing code. It is highly desirable that any refactoring is done in commits which are separate from those implementing the new feature. This helps reviewers and test suites validate that the refactoring has no unintentional functional changes. Even the newly written code can often be split up into multiple pieces that can be independently reviewed.

Track stock market information right in your Terminal.

     Introduction: As a developer, I love working with the terminal. The plain, simple, and in my opinion the best way to interact with the computer (also it makes you look geeky). I spent most of my time in the terminal. By now you must have guessed I am a huge fan of the terminal and terminal-based applications. Recently I developed an interest in stock markets and started tracking the stock markets. Since I love working with the terminal I decided to build a terminal oriented application that can help me to track the stock market. Inspir e d by  wttr.in  I build  terminal-stocks  which can provide the stock's current prices, historical prices, and global market summary. How to use terminal-stocks terminal-stocks  is available and can be used without installation. Get the current price of the stock. curl terminal-stocks.herokuapp.com/ITC.NS Current price of stocks You need to provide the ticker of the stock and terminal-stocks will give you the price information of the stock.  t

Setting up Nginx as a reverse proxy for Node.js App

Okay.. but what is a reverse proxy? A reverse proxy is a web server that centralizes internal services and provides unified interfaces to the public. Requests from clients are forwarded to a server that can fulfill it before the reverse proxy returns the server’s response to the client. Nginx is a popular choice to use as a reverse proxy for your node.js application. Got it. Now let’s set up Nginx Let’s say your nodejs server is running locally on localhost:3000. We will set up Nginx to get the request and forward the request to our nodejs server. Ins t alling Nginx on ubuntu sudo apt-get update sudo apt-get install nginx Configure Nginx Disable the default, virtual host unlink /etc/nginx/sites-enabled/default 2. Create a configuration file cd /etc/nginx/sites-available sudo nano reverse-proxy.conf 3. Put the following content in the file server { listen 80; listen [::]:80; access_log /var/log/nginx/reverse-access.log; error_log /var/log/nginx/reverse-e

RESTful CRUD API with Deno, Oak and MongoDB

In this post, we are going to build a RESTful CRUD API with Deno, Oak and MongoDB as database. In the previous article, we discussed how to install deno in your local machine and start using Deno. If you haven’t read that article, please read the article below and install the deno first. Getting started with Deno, Your first app Hello Deno. Let's install Deno. Deno ships as a single executable with no dependencies. You can install it using the installers… blog.shashi.dev After installing the Deno, we will start building the restful crud api’s. We will use o ak  microframework. Some of the other deno microframeworks are: abc deno-drash deno-express oak pogo servest In this article we will be using oak, which is inspired by koa. Setting up the project: Create a new directory called  restful-api-deno mkdir restful-api-deno 2. After c r eating the directory just  cd  into the directory cd restful-api-deno 3. Create a new file  server.ts  and paste the following code init. import { Ap
