海外TECH	DEV Community	Basics of Building a CRUD API with Typescript (NestJS and FoalTS)	https://dev.to/alexmercedcoder/basics-of-building-a-crud-api-with-typescript-nestjs-and-foalts-4h49	Basics of Building a CRUD API with Typescript NestJS and FoalTS Using Typescript for development for frontend and backend development keep growing Typescript allows for better IDE hints and less runtime errors due to type errors with its typing system On top of that Typescript makes popular OOP patterns like dependency injection more applicable vs when typing doesn t exist like in plain javascript In DI you use typing in class constructor to instantiate and inject services throughout your application Two frameworks keep typescript close to their hearts when building a backend application in NodeJS NestJS and FoalTS In this tutorial we will discuss CRUD and REST API conventions and apply them to building a basic API in Nest and FOAL Summary of RESTful ConventionTHe restful convention gives us a blueprint of making the basic routes for CRUD Create Read Update Delete functionality in a uniform way API Restful RoutesName of RouteRequest MethodEndpointResultIndexGET modelreturns list of all itemsShowGET model idreturns item with matching idCreatePost modelcreates a new item returns item or confirmationUpdatePut Patch model idUpdated item with matching IDDestroyDelete model idDeletes item with matching IDIf we weren t build an API but instead rendering pages on the server there would be two additional routes New which renders a page with a form to create a new object submitting the form triggers the create route Edit which renders a page with a form to edit an existing object submitting the form triggers the Update route Since we are building an api Edit and New aren t necessary as the burden of collecting the information to submit to the Create and Update route will be on whoever builds the applications that consume the API Frontend Applications built in frameworks Building an API Setupcreate a folder for this exercise and navigate your terminal to that server let s create our two project NestInstall Nest CLI Globally npm i g nestjs cliCreate a new nest project nest new n practicecd into folder and run dev server with npm run start which default runs on port localhost FoalInstall the Foal CLI Globally npm install g foal cliCreate a new Foal Project foal createapp f practicecd into folder and run dev server with npm run develop which default runs on port localhost Creating our ControllerA controller is a class where we will house a bundle of functions These functions will fire when certain requests are made to our server based on their request methods GET PUT POST PATCH and the endpoint this that The rules of which methods endpoint combinations point to which controller methods are called our routes In both of these frameworks routes are defined as function decorators decorator that designate the route each function belongs to create a new controller NestJS run command nest g controller posts creates src posts posts controller ts FoalTS run command foal generate controller posts create src app controllers posts controller ts For FOALTS make sure to update app controller ts to register the new controller import controller IAppController from foal core import createConnection from typeorm import ApiController PostsController from controllers export class AppController implements IAppController subControllers controller api ApiController controller posts PostsController lt async init await createConnection Now let s update and test each of the RESTful routes in our controllers Our DataWe aren t using a database so instead we ll use an array as our data layer Keep in mind if the server restart the array will reset itself need databases for persistent data Since we are using typescript we can define our data type Post and create an array of posts Put this at the top of your controller files Interface Defining the Shape of a Postinterface Post title string body string Array of Postsconst posts Array lt Post gt title THe First Post body The Body of the First Post The Index RouteThe Index route allows us to get all items of our model with a get request So in our case a get request to posts should get us all the posts Update the controllers as show below and then go to posts in your browser NESTJSimport Controller Get

海外TECH	DEV Community	Don't Launch Now - Things I Learned From My Launch and Development Hell	https://dev.to/madebyayan/don-t-launch-now-things-i-learned-from-my-launch-and-development-hell-32mm	Don x t Launch Now Things I Learned From My Launch and Development HellLaunching can be hard but not launching is even harder This is a bit of a long post and is divided into several sections For your convenience this study consists of the following sections Having A Product But Not Being Able To LaunchDevelopment HellA Post or two A HopeThe Week Before LaunchThe Launch Day FixEnd Of Launch DayLessons LearnedAbout The Product Having A Product But Not Being Able To LaunchAfter working on Focus Wall for a while I decided that its time to finally launch since it had already passed its MVP stage a while back However something held me back from just launching it I had a decent website and the product was ready but I just couldn t get myself to launch it This would mainly be because I was being psychologically held back due to the fact that I didn t have a big enough following on any social media which led me to believe that I shouldn t launch now as it wouldn t be worth it unless people start showing more interest on social media And hence the launch didn t happen Development HellSo after that I naturally went on to building my next project Developing is the one thing that sucks me in and even though I enjoy it sometimes it feels like this passion is holding me back from truly achieving somethings as I just jump from one thing that excites me to the next one after its completed And as fun as developing designing and coding are there seemed to lack a meaning behind it all If other people aren t able to use the things I m making and take advantage of my tools and products then what s even the point of making them A Post or two A HopeIt s not always that something you read changes your perspective on things but when that does happen you start seeing things in a new light And that s what happened when I encountered this post on Indie Hackers Just as I was working on my new project I came across that post and reading it sparked something in me and made me realize that it s okay to just launch because I ve built something that I want and if I don t put it out in the world someone else who might want it as well might never get it At the same time I had also come across this post and it helped me understand how to handle social media in a way while developing my product I ve always wanted to post more about what I m building and my process but I never knew where to start So this post pointed in the a clear direction and now I ve got a bunch of GEMS to post And because of that twitter seems to have become a more relaxed place rather than a source of anxiety The Week Before LaunchAfter the development hell had somewhat faded I committed myself towards a single goal that within a week I d launch my product on Product Hunt So I left the current project that I had been working on and started polishing Focus Wall for the launch At the time I even wrote a comment on a post about my goals for the upcoming week During the week I shared progress of the product on Twitter and even slight details of it This resulted in my follower count going from to in less that a week which I consider to be a big achievement as I hadn t been active on social platforms prior to that The Launch Day FixThe Product Hunt Launch was right after the list refreshed I had been working on the first comment for about an hour and added it the launch page along with some generic screenshots What I didn t realize back then was that product hunt compress the images that you add and just having dark screenshots didn t look good especially on phone So I spent the next few hours completely redesigning the images and adding self made mockups and styles And as soon as I finished making one image I d upload it to the the page and then work on the next one After fixing the page and website with better images I did see the number of upvotes go up though I can t be certain if it was because of this or not Along with this I also had a sale going on over on itch io and a coupon for gumroad the two places where I uploaded the app I then wrote about the launch on reddit added a milestone on indie hackers and shared it on twitter And also added the product upvote hunt button to my site End Of Launch DayAt the end of the launch day Focus Wall ranked nd on Product Hunt with upvotes which I don t consider to be a bad rank for someone who just launched their very first product in fact its motivated me work harder on my next product the one I had kept on hold to release Focus Wall Along with that I had also gotten my very first customer within just the first hours of my launch and that got me excited to work on it further knowing that other people want it as well Though the traffic on gumroad wasn t the best the product was featured as one of the top products on itch io since it appealed to all sorts of developers And all of this traffic was totally organic I hadn t told any friends or family about the launch just to see where I can get without relying on any extra factors for the launch Lessons LearnedInstead of plain screenshots make sure to use better pics that stand out next time and to check how it looks on various displays Don t let social media give you anxiety if you just give it a bit of your time it ll become a relaxing place where you can not only show your products but even express yourself Don t let the fear of not launching now get to instead launch when you re ready rather than keeping your product in the shadows And this is a big part of the reason why I started building in public as well as it s better to have your product out there instead of keeping it hidden from someone who might need it And the above statement is further strengthened from all the sales I ve made so far It s made me realize that I wasn t the only one who needed this and if I hadn t released it it wouldn t have reached to people who wanted it And I guess that s the rewarding part about being a maker you not only have fun making what you enjoy but you also get to give people something that they need that only your unique product or solution can provide About The ProductFocus Wall is a clean dynamic desktop
