海外TECH	DEV Community	JavaScript for Making API Calls	https://dev.to/shittu_olumide_/javascript-for-making-api-calls-4lgk	JavaScript for Making API CallsThere are a variety of ways to make an API request with JavaScript ranging from plain JavaScript to jQuery to additional tools that greatly simplify the process In this article we ll utilize a standard JavaScript technique We ll change our code in following courses to make our API request in a variety of ways We ll also learn about several tools for working with asynchronous programming in the process APIs after all are asynchronous While we ll just be using async tools to make API calls in this part the async tools we ll learn may be used to other asynchronous JavaScript tasks as well We ll make an API request the old fashioned manner in this session using only vanilla JavaScript This old fashioned method is used by all of the tools that jQuery utilizes to perform API requests However we won t cover the jQuery technique in this section because the Fetch API is a far superior option Fetch is likewise based on this time honored method So while you may not utilize this strategy for the independent project in this area though you certainly may you will have a better knowledge of how technologies like Fetch function when we use them later in this section Starting OffWe won t include all of the code for setting up our environment in the next sections The sample code below is available in a fully functional webpack environment in the repository at the conclusion of the lecture If you re going to create this project from scratch you ll need to include a webpack environment which you can either build yourself or get from the repository at the conclusion of the class We don t require a tests directory because we aren t testing anything We don t need a js directory right now In this session we ll put all of our JS code in index js which is the same naming scheme we ve been using with webpack projects We only need to look at two files for the code sample below index html and index js HTML code lt html lang en US gt lt head gt lt title gt Weather lt title gt lt head gt lt body gt lt div class container gt lt h gt Get Weather Conditions From Anywhere lt h gt lt label for location gt Enter a location lt label gt lt input id location type text gt lt button class btn success id weatherLocation gt Get Current Temperature and Humidity lt button gt lt div class showErrors gt lt div gt lt div class showHumidity gt lt div gt lt div class showTemp gt lt div gt lt div gt lt body gt lt html gt For a location we have a basic form input There are also various divs for displaying errors temperature and humidity Let s have a look at the API call s code import from jquery import bootstrap import bootstrap dist css bootstrap min css import css styles css document ready function weatherLocation click function const city location val location val let request new XMLHttpRequest const url city amp appid YOUR API KEY HERE request onreadystatechange function if this readyState amp amp this status const response JSON parse this responseText getElements response request open GET url true request send function getElements response showHumidity text The humidity in city is response main humidity showTemp text The temperature in Kelvins is response main temp degrees To begin we ll look at our import declarations We have a click handler that pulls a city value from a form puts it in a variable named city and then erases the form field location val This section is just for review The following is the first line of the new code let request new XMLHttpRequest We create a new XMLHttpRequest or XHR for short object and save it in the request variable XMLHttpRequest is a little deceptive name These objects are used to interface with servers which is exactly what API calls are for They aren t only for XML queries As previously stated XML is a rather widespread data format used by APIs However JSON is becoming increasingly popular and XMLHttpRequest objects may be used with JSON as well as other forms of data not simply XML The URL for our API call is then saved in a variable const url city amp appid Add Your API Key This isn t required but it does make our code simpler to understand For the code to operate properly you ll need to add your own API key in YOUR API KEY HERE Because our string is a template literal with an embedded expression city the value that the user enters in the form is transmitted straight into our URL string via our city variable The remainder of the code is divided into three sections A function that monitors any changes to the XMLHttpRequest s readyState The request is really processed and sent A callback function that will be used to display results in the browser Let s start with the function that monitors the XMLHttpRequest for changes request onreadystatechange function if this readyState amp amp this status const response JSON parse this responseText getElements response Onreadystatechange is a property of our XMLHttpRequest object This attribute can be set to the value of a function that performs anything we desire We have an anonymous function an unnamed function set to the value of that property in the example above We could even tweak the code to just track changes in the ready state request onreadystatechange function console log this readyState If we did the console would show the following The comment has been included Opened Headers Received Loading DoneThese numbers represent the many states in which our XMLHttpRequest object may be found Because this is the initial state and the readyState hasn t changed yet you wouldn t see which corresponds to Unsent Note that if you attempt this in the console ESLint will complain about no unused vars This is due to the fact that the getElements method which we define later in the code is no longer in use To make ESLint feel better temporarily comment it out Also when you re finished be sure to restore the code to its original state We wouldn t want to do anything until this readyState is because the data transmission isn t finished yet At work this is classic async Once this is done and this if this readyState We ll do anything with the data if this status Why does this happen Is it necessary for this status to be included in our conditional We discussed how a response signals a successful API request in the last lecture To put it another way before our code analyses the data the API request must be successful and the data transfer must be complete When the conditional is true we execute the following code const response JSON parse this responseText This responseText is another built in property of XMLHttpRequest objects as you might expect Once a server answer is received it is immediately filled It should be evident by now that XMLHttpRequest objects are quite strong and perform a significant amount of work for us The built in JSON parse method in JavaScript is used to parse this responseText This guarantees that the data is formatted correctly as JSON data Otherwise our code won t identify the data as JSON and when we try to obtain data from it using dot notation we ll receive an error Working with APIs necessitates the use of the JSON parse method Other programming languages as we mentioned in a previous lecture include methods for parsing JSON as well Then using the data in the response variable we ll build a callback getElements response A callback occurs when a function calls another function In a moment we ll go through this in further detail Before we do that let s talk about XMLHttpRequest objects in more depth By placing a breakpoint within our conditional and then executing the code in the browser we can see exactly what characteristics an XMLHttpRequest object has request onreadystatechange function if this readyState amp amp this status debugger It s wiser to add a breakpoint from the Sources tab the sample above only demonstrates where the breakpoint should be placed An XMLHttpRequest object as you can see has a lot of capabilities Most of these assets aren t worth worrying about right now There are however a few that will come in use throughout this section responseText We ve previously talked about this It contains the response s text The identical text can also be found in the response property Status The status code is the API status code A score of indicates that it was a success There are a variety of different codes such as not found statusText As you can see it s OK With a status code of this is standard That indicates we re ready to go If anything goes wrong though we could get a more descriptive error message like not found or not permitted Let s get back to our new code let request new XMLHttpRequest const url city amp appid YOUR API KEY HERE request onreadystatechange function if this readyState amp amp this status const response JSON parse this responseText getElements response We ve covered everything except for the two lines below request open GET url true request send Except for the last two lines which are highlighted in the comment we ve covered everything We ve created a new XMLHttpRequest object and set a method to the onreadystatechange property to listen for changes in the object s ready state at this point in our code but we haven t done anything with it yet The request must still be opened and sent request open GET url true request send The method of the request in this instance GET the url which we saved in a variable named url and a boolean indicating whether the request should be async or not are all sent to XMLHttpRequest open We want the request to be async once more we don t want our users browsers to freeze The three parameters will nearly always be the same for the API calls we make in this section the only exception will be if you make a POST or other form of request instead of GET We send the request after we ve opened it The readyState of the XMLHttpRequest object will change as we ve already explained and the function we ve attached to the object s onreadystatechange will fire each time the readyState changes Finally our getElements method will be run when our conditional in the function we ve linked to the onreadystatechange property is activated A callback occurs when a function calls another function Callbacks may rapidly become perplexing particularly when one function calls another which in turn calls another and so on As a result they may be somewhat daunting to newcomers Remember that a callback is simply a function calling another function when you see scary looking callbacks in the real world In a later lesson when we cover the notion of callback hell we ll describe why callbacks may be so frightening For the time being it s crucial to understand that callbacks are one method JavaScript writers may deal with async code It used to be the sole option for dealing with async code Fortunately we now have access to new technologies that will make our life simpler Later in this section we ll look at some of these tools Because we need to wait till our conditional is triggered before using getElements we need to utilize a callback here Keep in mind that JavaScript is a non blocking language Even if some of the code is async it will continue to run Let s see what would happen if we didn t utilize a callback Note This code will not work It s meant to show why we need to structure our code to use a callback let response request onreadystatechange function if this readyState amp amp this status response JSON parse this responseText request open GET url true request send getElements response When we execute request send in the code above our request is submitted to the server Keep in mind that this will take some time Our request will be accepted or denied by the server and we will receive a response We must first wait for the answer to load before parsing it JavaScript on the other hand is not a blocking language That implies it won t wait for request send to finish before continuing The call to getElements response will happen right away and we ll get the following error Cannot read property main of undefinedThis is a typical async problem getElements response is not async although request send is When getElements is invoked the result will still be undefined since the function is still running The answer will be specified later but our code will break before that This is why a callback is required Let s look at our original code once more request onreadystatechange function if this readyState amp amp this status const response JSON parse this responseText getElements response function getElements response showHumidity text The humidity in city is response main humidity showTemp text The temperature in Kelvins is response main temp degrees getElements response will not be invoked in this code until the conditional is true In other words we ensure that the function doesn t start until we receive a response from the server by utilizing a callback One of the many essential use cases for callbacks is async code Callbacks can assist us in determining the order in which functions should be executed If we require a sync function to execute after an async function we may use a callback to ensure that the code runs in the expected sequence Of course when we need a sequence of sync and async methods to run in a specified order things may quickly get strange ConclusionWe covered how to build and send an XMLHttpRequest object in this lecture You should have a better knowledge of how JavaScript creates HTTP requests after doing so We also spoke about how to utilize callbacks to ensure that our code runs in the order we want it to	2022-01-23 23:02:15
