海外TECH	DEV Community	PHP isn't dead! Don't be afraid to use it and implement it in your projects...	https://dev.to/manuthecoder/php-isnt-dead-dont-be-afraid-to-use-it-and-implement-it-in-your-projects-2225	PHP isn x t dead Don x t be afraid to use it and implement it in your projects Ok Let s get this straight PHP is not dead It s not going to die anytime soon Why PHP released a new version recently actually just a few months ago It exists in more than of all websites It s also used actively by millions of developers None of that will disappear out of thin air Despite the fact that many new languages flourish every year I would not hesitate to say that PHP besides JS is one of the safest languages in the world in terms of jobs and will securely guarantee an enormous job market around the world for much longer than years Here is why PHP adopts new ideas slowly It may sound like a weird reason for a programming language to keep up with the contemporary development trends In fact what happens is only proven polished and time checked ideas find their way into PHP PHP has low entry level This means that it is one of the easiest languages to start coding for newbies ever Then once it is adopted by newbies it often turns out that this language is enough for a lot of people that do not need genius complex mathematical and scientific features Result they just keep using PHP Big platforms and companies which use PHP make lots of money every day WordPress for example which is made in PHP is a free framework but WordPress com is a commercial WordPress hosting and makes money out of it Then there are tens of others like it Now multiply this business volume by the number of other big PHP projects like shopping carts CRMs issue tracking systems web analytics And one of the biggest reasons Servers accessibility The cheapest servers VPS for web projects always support PHP PHP has one of the lowest minimum requirements to the memory processor speed Is PHP on the decline Yes Is it a crappy programming language Absolutely But that doesn t mean it s going away any time soon Consider COBOL An almost sixty year old language that s horrible by modern standards and has been on the decline for thirty years Yet it runs our financial infrastructure and there are still an estimated one million COBOL developers worldwide Maybe that is what PHP will be like in a couple of decades	2021-11-20 07:24:31
海外TECH	DEV Community	Adding Continuous Integration with GitHub Actions 🛠	https://dev.to/mqnguyen/adding-continuous-integration-with-github-actions-33hm	Adding Continuous Integration with GitHub Actions IntroductionWith static analysis tooling and unit tests added to the project it is time to increase the complexity of my project At the moment I have written several tests to check on the different functionalities of my program However they had to be manually run by executing npm run test in the terminal which will be very tedious if there are a lot of files to test Additionally we also need to consider human errors as there is no way to guarantee that all contributors remember to run the test before committing their code Choosing a CIWith this in mind it is to introduce continuous integration or CI for short It allows us to set up a workflow that listens to every time someone introduces new changes builds the code and automatically runs tests against it While we have many CI services such as Azure DevOps Evergreen or Jenkins I ll choose GitHub Actions for this task Setting up the CIThere are different options to set up GitHub Actions You can either choose to do it manually or choose from numerous templates My project MINI works just fine with the Node js template Title of the workflowname Node js CI Trigger this workflow on push and new PRon push branches main pull request branches main jobs to run inside this workflowsjobs build choose a platform to run on runs on ubuntu latest options strategy matrix node version x x steps use a preset step to checkout the code uses actions checkout v use a preset step to setup Node environment name Use Node js matrix node version uses actions setup node v preset options with node version matrix node version cache npm command to run run npm ci run npm testAfter setting up GitHub Actions I made two pull requests to check if it worked as intended One containing an intentional error and the other with the same error fixed Writing test for othersAfter ensuring that the CI was working I decided to file an issue to Tue s repo and asked if I could help him test his text to HTML conversion We worked with each other through Slack and GitHub with myself taking notes of what he wanted to check and what the expected results should be After struggling with managing and rebase commits when changing the code based on Tue s review I was able to merge my pull request ConclusionI intend to use continuous integration in additional projects in the future and it was helpful to understand how it works and how to set it up It makes collaboration considerably easier because it prevents unintended problems and code breaking changes Happy coding	2021-11-20 07:23:33
