海外TECH	DEV Community	Think like a PRO...grammer	https://dev.to/nombrekeff/think-like-a-pro-grammer-10k1	Think like a PRO grammer Hey there I was bored and wanted to write something I ve ended up with this a step by step guide on how I approach a task from the most basic to the best fitting implementation for the needs What will I build Piece of code for fetching data It will be fetching a jokes API which returns either a list of jokes or a random joke I will then try to improve it step by step until I have a solid and scalable base ContextNothing is built except for the API the task is to create a way of fetching the jokes so that the UI team can start doing their job Initial implementationMost simple scenario would be to create some sort of function that fetches all the jokes and one that fetches a random one Easy enough let s see how that works function fetchAllJokes return fetch then response gt response json function fetchRandomJoke return fetch then response gt response json As you can see this would immediately work and let the UI team do their job right now But it s not very scalable let s see how to improve on this without breaking anything for the UI team Iteration We know that for now we can only get jokes but we also know that most likely this API will expand in the future And we will need to implement other stuff like creating updating jokes Fetching other resources etc One thing I try to remind myself before I start to build or design a feature is can I make it so I don t have to touch this code again Most times the answer is yes by kind of using the open close principle which states that a function method class should be open for extension but closed to modification Another rule I try to apply to myself is work yourself upwards What I mean is start from the most simple low level functionality and then start building on top of that In this case the lowest level functionality is executing fetch with a set of options So I start by defining a custom function around fetch function fetcher url options return fetch url method HttpMethods GET options It s mostly the same as calling fetch directly but with a difference It centralizes where fetch is called instead of calling fetch directly in several places in the app we only use it in the fetcher function It s easier to change modify in case fetch API changes or we want to do something before or after each fetch request Though I would resist it if it can be avoided as you will see later on in the post Now that we have this base we can start building on top of it Let s make it possible to use the most common HTTP methods like POST PUT GET DELETE function fetcherPost url options return fetcher url options method HttpMethods POST function fetcherPut url options return fetcher url options method HttpMethods PUT I think you get the gist of it We create a function for each method We would use it as follows function fetchAllJokes return fetcherGet then response gt response json function fetchRandomJoke return fetcherGet then response gt response json This is ok but we can do better Iteration The API uri will probably be the same in all requests and maybe other ones too So let s store that in an env variable function fetchAllJokes return fetcherGet env API URL jokes then response gt response json Better now you can see that converting response to JSON is also being repeated How could we improve this First let s see how NOT TO DO IT which would be to just add it to the fetcher function in the end all requests pass through it right function fetcher url options return fetch url method HttpMethods GET options then response gt response json function fetchAllJokes return fetcherGet env API URL jokes Yes we get rid of it in the fetchAllJokes function but what if a request does not return JSON We would need to then remove it from the fetcher and add it again to only those requests that return JSON Wasting time changing stuff we have already done and remember the rule can I make it so I don t have to touch the code I write again Now let s see HOW TO DO IT I want to express that there are always many correct ways to solve a problem this is one of them It s in no way the only or best solutionOne option would be to extract the functionality into a function for example function jsonResponse response return response json Then we could use it as followsfunction fetchAllJokes return fetcherGet env API URL jokes then jsonResponse And if we receive other formatfunction fetchAllJokes return fetcherGet env API URL jokes then xmlResponse This is a good approach as it lets us process the response afterward depending on the data returned We could even extend the fetcher function for each data format function jsonFetcher url options return fetcher url options then jsonResponse function xmlFetcher url options return fetcher url options then xmlResponse This approach is even better in some senses as we can check things like headers body etc on each request For example we want to ensure that with json requests a header of type application json is sent function jsonFetcher url options const isPost options method HttpMethods POST const hasHeaders options headers null if hasHeaders options headers if isPost options headers Content Type application json return fetcher url options then jsonResponse Now any time a post request is made with jsonFetcher the content type header is always set to application json BUT and a big BUT with this approach you might have spotted a problem We now have to create new functions for each method fetcherGet fetcherPost for each fetcher Iteration This could be improved by rethinking how we create fetchers instead of overriding the fetcher function we could return an object containing all methods for that specific fetcher One solution to this problem would be to create a function which receives a fetcher and returns an object with all methods attached function crudForFetcher fetcher return get url options return fetcher url options method HttpMethods GET post url options return fetcher url options method HttpMethods POST more methods Create fetch for each fetcher typeconst fetchDefault crudForFetcher fetcher const fetchJson crudForFetcher jsonFetcher const fetchXml crudForFetcher xmlFetcher fetchJson get my api com hello There s still a thing that s bugging me a bit it is that we need to pass the full API URI in each request now it s really simple to add this functionality as we have it all broke down What we can do is improve the crudForFetcher function a bit more by making it receive some options function crudForFetcher fetcher options uri root const uri root options return get path options return fetcher path join uri root path options method HttpMethods GET more methods const jokesFetcher crudForFetcher jsonFetcher uri env API URL root jokes What this change does is merges the URI root and path of a specific request into a single URI In the case of jokesFetcher the URI for the requests will always start with We can now safely replace our original functions without the UI team needing to change anything but we now have a lot more power and ready to scale yay function fetchAllJokes return jokesFetcher get function fetchRandomJoke return jokesFetcher get random As you can see we have not modified anything we ve built except for crudForFetcher Everything put togetherfunction fetcher url options return fetch url method HttpMethods GET options function jsonResponse response return response json function jsonFetcher url options return fetcher url options then jsonResponse function crudForFetcher fetcher options uri root const uri root options return get path options return fetcher path join uri root path options method HttpMethods GET post path options return fetcher path join uri root path options method HttpMethods POST Exposed APIconst fetchJokes crudForFetcher jsonFetcher uri env API URL root jokes function fetchAllJokes return jokesFetcher get function fetchRandomJoke return jokesFetcher get random SummaryWe ve taken a simple implementation and bit by bit building up until we have something that will scale quite well without breaking anything along the way with a bit more refinement work of course I ve been using this approach for the last couple our years in a variety of projects frameworks languages etc and it s working out pretty well for me It s also been really productive in the sense that it has reduced the amount of work I need to do significantly And just to reiterate this is one approach of many that could work in this scenario I might post a different approach using oop What to take out of this Understand the task at handLook at the forest not just the trees don t just implement the feature think about it and the stuff around it Build things progressively but not recklesslyMake functions methods as closed as possibleKeep things simpleI really enjoyed writing this and I hope you like the read as well If you did consider supporting me by reacting to the post following me here or over on GitHub or commenting ️	2021-08-21 13:37:41
