海外TECH	DEV Community	Are You Really API-First Or Do You Just Think It?	https://dev.to/aws-builders/are-you-really-api-first-or-do-you-just-think-it-1h8o	Are You Really API First Or Do You Just Think It I recently had the opportunity to meet with Postman executives and other industry leaders in the API space It was a terrifying exhilarating and humbling experience We talked about everything from developer experience to API lifecycle to API first development to even the future of the API landscape It was awesome I make it no secret that I m passionate about two things serverless and APIs To be in the midst of the most passionate API heads around was invigorating When we started having conversations around API first development something caught my attention I have been talking about being API first for years thinking I was doing it but when we talked about the nuance of implementation I quickly realized what I thought was a lie Ok not really a lie but I was under the wrong impression What I discovered is that you might be under the wrong impression just like I was So let s talk about it and figure out if you actually are developing API first or if you just think you are What Is API First I will never explain this as well as Kin Lane from Postman does He can explain all the aspects of being an API first company in points High level API first means that you prioritize your APIs as your product You put intentional strategy into their design implementation security and discoverability While these traits might sound like obvious components to focus on it s really the context that is the differentiator Traditionally you ll see companies that put the focus on design security discoverability etc into the application they are building Meaning the full stack app they are shipping off to customers This inherently isn t an issue but it isn t API first With API first the context is your API It s the mechanism used to manipulate your system You put your emphasis there so integrators have the same keys to the system as you with a few exceptions API first is about a mindset shift from building custom applications for your consumers to enabling them to build it themselves Take the hassle off of you to create and maintain custom apps Provide a meaningful developer experience for your consumers and they will flex your system in ways you never expected If you think you do this already so did I Let s discuss what all this means when it comes to the day to day What Does That Mean When putting API first development into practice the detail really surfaces in standard process changes you ll have to make It s not just the order of events that needs to change but the effort that goes into structuring the work Defining the WorkThe first phase of API first is define The definition phase of API development involves more than just developers It involves the business and product units working with development to clearly define the functionality this API is intended to bring What business problems are you trying to solve What data entities are involved What is the lifecycle of each of these entities More detailed questions like should this be a PATCH or a PUT how should we structure the endpoint format and how do we handle paging should already be answered questions and defined in your governance model If you don t already have a governance model in place that would be a good place to start If you don t know where to start on building a governance model you can use the Postman Open Technologies Governance Rules collection as a foundation Governance rules are meant to be iterated on So find what you like make modifications and address anything new that comes up The important part is that you start somewhere Approaching the work in this manner is the same whether you are creating a brand new API from scratch or adding functionality to an existing one Getting the group together to discuss the business objectives and clearly define the problem area is always step one Splitting Up StoriesWhen I first started with my version of API first I was under the impression that it meant all I had to do was work on the endpoint stories first API first does not mean simply doing your API stories before your UI storiesIn fact it is totally viable to work on the UI and API implementation at the same time with API first development Your first set of stories is building out the API spec which includes endpoints schemas and examples for your requests and responses Once those are completed you can create a mock server which will return fake data in the expected format With this in mind your UI development can begin while you start the real implementation of your API Remember with this development approach you treat your API as your product Any UI you build on top of it is a value add Testing and MonitoringResiliency and robustness are key success indicators in API development To test these components your APIs should have a variety of different tests that stress them in different ways Contract tests verify the API accepts and returns the correct schema in the request and responsePerformance tests makes sure your API returns a response in the expected amount of timeSecurity tests determines if your API has the correct access control around data and endpointsEnd to end tests run workflows through the system to make sure different business objectives can be completedNot only should you have each of these tests for your API but you also need to have a way to make sure they aren t throwing errors Use any sort of APM like DataDog New Relic and even Postman to monitor the success rates of your tests and notify the proper team when something stops working Including automated API tests as part of your definition of done is an indicator you are doing API first right If you aren t running these tests as part of your development cycle you need to start Contract tests and performance tests can be dynamically generated But for end to end tests you need to put some conscious manual effort into making those run real world scenarios The better you can automate the scenarios your consumers are running the higher likelihood you won t push out a breaking change Making Your API DiscoverableWhen I was managing a cloud native dev team we would complete the work on a new API and move onto the next story Other teams around my company would have no idea there was a new API and in the off chance they found out about it they would have no idea how to find it and integrate with it Heck even developers on my team would have a hard time finding details on an API This is because we weren t making our APIs discoverable Imagine you re selling your house and your realtor lists it on online on their website They don t put a sign in your yard or advertise it on social media Chances are your house isn t going to sell in any reasonable amount of time This is because it isn t discoverable How are buyers supposed to find your house Do they have to know to look at your realtor s website That s not going to happen The same thing applies when you re building an API You need to surface it an a place people know where to look then advertise the crap out of it If people have to ask you where to find the documentation for your API or what APIs you have available consider that a red flag that you aren t doing a great job with discoverability Postman has both a public network and a private network to make it easy for you to share your APIs externally and internally ConclusionAPI first means treating your API as your product To do that your focus and emphasis has to change You aren t driving design decisions based on where you think a user should click Instead you re thinking about how you can easily let integrators chain requests together to complete a business scenario Work across the organization to design your API spec in a meaningful way Iterate the design until you re happy with it Don t start writing code until the spec is complete Put renewed attention on monitoring capabilities Change your definition of done Don t accept anything that needs to be manually tested every time a change is made Automate the tests and notify the team when it breaks Let the world know what you ve done Put your APIs in a network that allows them to be easily discovered Don t rely on word of mouth and tribal knowledge when your API is done Your dev team doesn t scale They can t work on new APIs and evangelize the APIs they already completed This development approach feels like it turns standard development on its head And that s a good thing Disruption drives innovation By pivoting your organization to focus on APIs and developer experience you open the doors to things you never thought possible People are creative If you give them the keys to your API they will make it do things you never thought imaginable Which is what we re all here for Happy coding	2022-06-01 12:25:57
海外TECH	DEV Community	Hoisting in JavaScript 🔥 😍[Visually Explained]	https://dev.to/narottam04/hoisting-in-javascript-visually-explained-cfa	Hoisting in JavaScript Visually Explained Developers often have a love hate relationship with JavaScript because sometimes it doesn t work as expected Learning JavaScript fundamentals and its quirks can assist developers in debugging and writing clean code This blog post aims to explain one such peculiarity i e hoisting using animated gifs After reading this blog you will be one step closer to becoming a Rockstar Developer Execution of JavaScript code Before understanding the concepts of hoisting let s first learn how javascript will run code behind the scene through an example var a var b var sum a b console log sum In this simple example we initialize two variables a and b and store and respectively Then we add the value of a and b and store them in the sum variable Let s see how JavaScript will execute the code in the browser When the JS first receives our code it will create an execution context Execution context will first scan through all the code and allocate memory to all the variables and functions For variables specifically var JavaScript will store undefined in the memory and for functions it will keep the entire function code reference in memory Now that we have scanned and allocated memory to the code we can execute the code JavaScript will again start going through the whole code line by line As it encounters var a  it assigns to a in memory Until now the value of a was undefined Similarly it does the same thing for the b variable It assigns to b Then it calculates and stores the value of the sum in memory which is Now in the last step it prints the sum value in the console and then destroys the global execution context as our code is finished If you want to learn more about execution of code in JavaScript I wrote an article about it on the dev community Link How Javascript works explained visually Hoisting in varTo understand hoisting in a variable defined with var let s take the example we took in the execution of code However in this example we re going to print the sum at the beginning not at the end console log sum var a var b var sum a b The above code would throw an error in other programming languages but not in JavaScript As we saw in the section on the execution of code when JS first receives our code it will create an execution context Execution context will first scan through all the code and allocate memory to all the variables and functions Now after scanning the code it will start the execution of the code line by line In the first line javascript checks the value of sum in memory and prints undefined as an output Now as it encounters var a it assigns to a in memory Until now the value of a was undefined Similarly it does the same thing for the b variable It assigns to b Then it calculates and stores the value of the sum in memory which is If we console log after we calculate the sum let s see the output Initially it will print undefined after computing the sum it will print This peculiarity in javaScript is called hoisting Let s learn hoisting in let const keywords and functions Hoisting in let and constWhen we refer to a variable declared with the var keyword before its declaration it simply returns its default value undefined However as demonstrated in the previous example this can sometimes result in unexpected behavior Therefore ES introduced two new JavaScript keywords to combat this unexpected behavior let and const These two keywords are Block Scope To keep this article concise we would be learning more about the scope in another blog Let s see the hoisting in let and const through an example console log a console log sum var a let b const c const sum a b c So let s start with the execution of code again when JS first receives our code it will create an execution context Execution context will first scan through all the code and allocate memory to all the variables and functions I know I ve mentioned this multiple times but it s important As opposed to var where undefined is stored in memory let and const variables are uninitialized After scanning the code it will start executing the code line by line The first line will print the value of a i e undefined in the console But when we try to access a let and const keyword before initialization a ReferenceError gets thrown whenever we try to access uninitialized variables Uninitialized variables cannot be accessed since they are in a temporal dead zone Temporal dead zone simply means we don t have access to the variables before declaration If we try to print the value of b instead of the sum the result would be the same The value of the sum must be printed once the deceleration of the value to the variable is complete Here is the visualization of the execution of code Hoisting in functionWhen javaScript begins scanning code and comes across a function it stores the function s reference in memory It is the reason why we can invoke the function before we have created it Let s see it in action through an example printSum function printSum a b const c a b console log c The output of the following code will be Let s try to visualize first JavaScript will scan the code it will encounter a function in the rd line and it will add a reference of the function to the memory Javascript will now run the code line by line It comes across a function on the first line When a function is executed in javascript it creates a new execution context within our global execution context Consider the function execution context to be a mini execution context with its memory and a location to execute the code in the function Read more about how functions execute code in this blog post Once all the code inside the function is executed the execution context of the function is destroyed ReferenceNamaste JavaScriptI hope this post was informative Feel
