海外TECH	DEV Community	Let's discuss Generics in TypeScript	https://dev.to/toluagboola/lets-discuss-generics-in-typescript-3d0p	Let x s discuss Generics in TypeScriptThis article will discuss Generics their syntax their importance and use cases PrerequisitesTo succesfully follow and understand what will be explained you need to have the following installed NodeJSTypeScriptYour IDE of choice Now what are Generics Generics are a way to define reusable functions classes and interfaces that can work with a variety of types instead of a single type Generics basically enable us to keep them generic by making them work according to the passed type s Take the following function that returns whatever is passed function returnArg arg string string return arg let a returnArg Cat console log a Cat We can see that it will not be possible to pass a number to this function and that is because of the explicit annotation that specifies that it will only accept a string If we wanted it to work with numbers one thing we can do is define another function that accepts a number function returnArg arg number number return arg let b returnArg console log b This will work fine but it results in code repetition which is time consuming and isn t intuitive An alternative is to set the type of the argument to any function returnArg arg any any return arg let a returnArg name Cindy Using any will have the same effect as generics However it will cause our program to lose the information about what type was passed and what type will be returned This means that it is not type safe and defeats the purpose of type checking That s where generics come in With this approach we can make the above function work with data of any type without rewriting it Let s create a generic version of the returnArg function function returnArg lt T gt arg T T return arg let a returnArg let b returnArg a a let c returnArg cat mouse cat mouse let d returnArg name Tolu age name Tolu age The above function uses what is called a type variable which is a special kind of variable that works on types only and not values It is usually captured within angle brackets Whatever data type is supplied at the time of the function call is captured in the type variable T to be used later This allows our function to work on a variety of types while maintaining type safety and preventing code repetition As we can see in the variables above returnArg will accept any data type that is passed into it without losing any vital information about what type is passed Using Generics with multiple parameters of different typesIf there are multiple parameters in a function you can represent each of them within a type variable list like this function returnArg lt A B C gt arg A arg B arg C arg A arg B arg C return arg arg arg const a returnArg Tolu true console log a arg arg Tolu arg true The type variables A B and C are generic types for whatever arguments will be passed Generic interfacesNot only functions can be generic Interfaces and classes can too Here s how a generic interface is written interface A a lt T gt b lt U gt c lt V gt To write a generic interface we can pass generic types to an interface definition just like functions It s members will reference the passed types as seen above If for example we want to represent a person with a generic object we can create a generic interface for it like this interface Person lt A B C D gt name lt A gt age lt B gt likesToEat lt C gt callName lt D gt const person Person lt string number boolean gt void gt name Tolu age likesToEat true callName function alert this name At the point of use of the interface we are to supply the specific types that we want the type variables to represent as shown in the person variable declaration Generic classesclass Pair lt T U gt first T second U constructor first T second U this first first this second second In this example we ve defined a Pair class that can hold two values of any type The type variables T and U in the class declaration indicate that the class is generic and that the types of the first and second values will be determined when the class is used The Pair class has two properties first which holds the first value and second which holds the second value We can create instances of the Pair class with any type of data like this const booleanAndString new Pair lt boolean string gt true Alice const objectAndNumber new Pair lt greeting string number gt greeting hello In the first line we create an instance of Pair with a boolean and a string In the second line we create another instance of Pair with a number and an object that has a greeting property This goes to show the flexibility that generics afford us ConclusionGenerics are an important feature of TypeScript that allow us to write functions interfaces and classes that can work with any data type This creates flexible reusable concise and type safe code which contributes to high quality applications that are easier to maintain It is worth it to learn about generics and how to put them to effective use within your applications I hope that you have gotten some value from this article Kindly leave any questions or additional information in the comment section Thanks for reading	2023-03-14 09:40:00
海外TECH	DEV Community	Using Docker for Rails development	https://dev.to/2nit/using-docker-for-rails-development-1928	Using Docker for Rails developmentRecently I got assigned to an old project and while luckily it had instructions on how to set it up locally in the Read me the number of steps was damn too high So instead of wasting half a day executing them I wasted days automating them future devs will thank me…maybe I wanted to get as close as possible to a one command local env setup To simplify the process as you have guessed from the title of the article I decided to set up docker and docker compose I started with an example config from awesome compose Level just get the app to run on dockerFROM ruby WORKDIR myappCOPY Gemfile myapp GemfileCOPY Gemfile lock myapp Gemfile lockRUN bundle installCOPY myappCOPY config database yml example myapp config database ymlCMD bundle exec rails s p b I won t enter into details too much the main concept is first copy just the gemfiles and install gems this is done to take advantage of the caching mechanism in building images to speed up rebuilding copy the rest of the app codecreate a config file for the database based on a template the details will be passed through ENV variables Since this time the goal is local developments assets compilation is not an issue we want to optimize Next the maestro orchestrating the local env docker composeservices db image postgres volumes tmp db var lib postgresql data environment POSTGRES PASSWORD password web build command bash c rm f tmp pids server pid amp amp bundle exec rails s p b ports environment POSTGRES HOST db REDIS URL redis redis REDIS HOST redis depends on db redis redis image redis alpine command redis serverMost of it is thanks to the help of awesome composeWhat we want to achieve here Run our app alongside a postgres database and a redis serverHave the postgres database data persistUse env variables to pass the component names for routingAs a warning note avoid mapping any port that s not necessary So no mapping of for postgres db While it s not an issue for local dev if you use a similar config on a production server it could open you to some brute force attacks The odd thing you may have noticed that we have both a REDIS URL and a REDIS HOST env It s because the default redis cache use requires the url param to have the protocol redis at the beginning but our app also uses redis store for session store which requires just the host without the protocol Chances are you don t use redis store and can safely remove the unnecessary env Level add some dev quality of life configsSo this config was enough for me to get rolling and work on the project and contribute but it s not the most comfortable thing due to a couple of issues Any change to the code required turning off the docker compose instances rebuilding and turning the infrastructure on again and that adds up I can t use binding pry do debugSo to be able to cut on the restarts necessary and auto update code we will use volumes web build volumes myappAdding a volume will mirror the current dir to the app dir in the image will automatically mirror any change we make to the code While this won t help with changes to config files it will handle most changes in real time Assuming we run on typical dev env configs To enable access to binding pry you need to add the following to the web service web build volumes myapp tty true for binding pry stdin open true for binding pryBut adding this won t allow us to just access the debug console from the console used to run docker compose we will need to find the id of the web process and connect to it docker ps docker attach cdeab Level add some reusability and sidekiqOne last thing missing now in my case was the possibility to also run sidekiq It was not necessary in the beginning but once the development went on we needed to work on some async tasks to handle long data import processes x my app amp my app build volumes myapp environment POSTGRES HOST db REDIS URL redis redis REDIS HOST redis depends on db redis tty true for binding pry stdin open true for binding pryservices db image postgres volumes tmp db var lib postgresql data environment POSTGRES PASSWORD password web lt lt my app command bash c rm f tmp pids server pid amp amp bundle exec rails s p b ports sidekiq lt lt my app command sidekiq L log sidekiq log C config sidekiq dev yml P tmp pids sidekiq pid redis image redis alpine command redis serverSo as you can see before starting to define services we created a block that will contain all the common configs between the rails app and the sidekiq process containers The only differences are the command and the ports since sidekiq doesn t need any open and we can t have containers trying to occupy the same port anyway And with this addition I d consider the docker config done for this project While it still requires more than one command to setup initially with the database creation migration seeding it s a step requiring additional scripting on top of docker compose Maybe for another article The commands toolboxAs a parting note i d like to list the docker command i found myself using most often docker compose up build start the appdocker compose down stop it if running in the backgrounddocker compose ps check the status of currently running imagesdocker compose run web bash run commandsdocker images show list of built imagesdocker image prune delete unused images since they can take up a lot of hard drivedocker ps docker kill if docker compose not doing the jobTip you may consider creating an alias for docker compose to avoid typing it every time	2023-03-14 09:32:27
