海外TECH	DEV Community	Build a Restful CRUD API with Node.js	https://dev.to/zagaris/build-a-restful-crud-api-with-node-js-2334	Build a Restful CRUD API with Node js What CRUD API means The CRUD paradigm stands for the four primitive database operations that are CREATE READ UPDATE and DELETE So with the term CRUD API we mean the API which have the ability to create read update and delete entities from a database For this example the entity is the employee Let s BeginAPI Endpoints are the followingMethodsUrlsDescriptionGETapi employeesGet all employeesGETapi employees idGet a specific employeePOSTapi employeesCreate a new employeePUTapi employees idUpdate an existing employeeDELETEapi employees idDelete an existing employeeWe create the repository and install the dependencies The entry point is the server js file mkdir express api cd express api npm init npm install express helmet morgan body parser monk joi dotenv save npm install nodemon save devAbout the packagesexpress It is a minimal and flexible Node js web application framework helmet It helps in securing HTTP headers in express applications morgan It is an HTTP request logger middleware for Node jsbody parser It is responsible for parsing the incoming request bodies monk A tiny layer that provides substantial usability improvements for MongoDB usage joi It is an object schema description language and object validator dotenv It loads environment variables from a env file nodemon It restarts automatically the node application when file changes in the directory have been detected Setup Express Web Server src server jsconst express require express const morgan require morgan const helmet require helmet const bodyParser require body parser require dotenv config const app express const monk require monk app use helmet app use morgan dev app use bodyParser json const port process env PORT app listen port gt console log Listening on port port Create and configure the env file envIt contains all the enviroment variables that we use TEST DB URL variable is for test cases in order to prevent the insertion of test data in the database Also you can specify the port number you want DB URL localhost my

Listening on port port We go to the package json file and replace the script section with the following scripts start node src server js dev nodemon src server js The command npm start starts the Node

海外TECH	DEV Community	Python Business Idea: What You Must Do If You Know Python	https://dev.to/motivatedman/python-business-idea-what-you-must-do-if-you-know-python-2anb	Python Business Idea What You Must Do If You Know PythonBesides the fact that Python is one of the most in demand languages globally so it can be a great language to get a job everyone can try many other easy business ideas You might do a job or you have just finished the language and thinking to start working on it In whatever circumstances you are the following startup idea will worth your time Let s start with the story how I discovered that Python could be highly beneficial for any developer as a side business and as a full time business I was researching web development business ideas and I realized that many people make some handsome money without much effort even with a single language Many developers are teaching Python on YouTube and there are millions of views on each video Let s see how much beneficial it could be to start a YouTube channel to teach Python Starting a YouTube ChannelYouTube was started back in it was an entertaining platform but that s an older thing People have literally changed in the last two decades For instance they moved from Yahoo to Google and Facebook So they moved to YouTube It did not remain an entertaining platform and became the second largest search engine with the largest content data The monetization of video gave people a huge opportunity to become self employed To make a long story short it s has become th biggest opportunity to help people solve their problems But solving problems won t be for nothing It will give you huge benefits in return And as Python has been a highly in demand language if you simply teach pretty easy things on your YouTube channel that you start it will be highly paying The question might arise in your mind How can it be highly beneficial to start a YouTube channel The reason is that RPM and CPC for this language are pretty high CPC of Keyword Python Tutorial It s huge Secondly all those learning Python are not ordinary users They are premium users many of them will buy apps for development like MockPlus or Adobe Dreamweaver And some will be interested to learn it hard from your premium course For example someone I trusted recommended me Rapidload for my blog and I just purchased it without any hesitation The third income source for your channel will be sponsors once you build an audience you will simply get dozens of opportunities to make sponsored videos Thus wherever you are whatever you are doing the YouTube business could be your biggest side business that will make you self employed pretty soon Your channel will be your asset Each video you make will be the property of your channel so if you even make fewer videos once the effect will be the compound effect How much will it cost to start your channel If you made your mind to your channel the next question surely be the startup cost It won t be a high amount of channel Let s accumulate it You need a laptop for your startup Indeed you must already have one but if you don t have one then you can get it for under  Here are the best fastest laptops under dollars Become YouTube Master in a day It will cost you almost free You can pick any course from Udemy I got this one for you So overall it will be a total of investment if you already have a laptop otherwise it will be up to That s not a big deal because in return you will be making thousands of dollars a month	2021-10-07 19:19:55
