海外TECH	DEV Community	API: Def, Types, Spec, and Docs. A stone's throw into the application programming interface.	https://dev.to/dulemart/api-def-types-spec-and-docs-a-stone-s-throw-into-the-application-programming-interface-2g4i	API Def Types Spec and Docs A stone x s throw into the application programming interface You don t have to be around the tech space for months before coming across the word API Words like API shouldn t be a new thing to anyone that reads tech magazines or blog posts like what you are doing now one thing reading of blog post and a tech magazine helps you with is getting familiar with buzzwords in the tech space Before learning web development the word API sounded like a complex term that would be difficult to understand and start running with Over time the term has become a frequently used word companies are now developing API as a product and creating a role for documentarians to help them organize and structure words that will enable their users to use their API without any difficulty I got to know about the history of API after reading about it on RED HAT APIs emerged in the early days of computing well before the personal computer At the time an API was typically used as a library for operating systems The API was almost always local to the systems on which it operated although it sometimes passed messages between mainframes After nearly years APIs broke out of their local environments By the early s they were becoming an important technology for the remote integration of data Technically API stands for Application Programming Interface Most large companies have built APIs for their customers or for internal use or as a Product as a means of collaboration between two different and remote companies The Web as an InstanceThink about the Web as a large network of connected servers where we make a request through HTTP and get a response that is been define in a structured way The web provides information to users from a remote server every web page on the internet is stored somewhere on a remote server that receives request and process response When you type a web address into your browser a request goes out to the web remote server Once your browser receives the response it interprets the code and displays the page API Def While the acronym is commonly referenced few understand its actual meaning Like we clearly stated above what the acronym represents Understand that software is built to communicate this is the whole essence to while most software applications are built with the integration of APIs that serve then data from other applications it could be to communicate with a store by placing orders and check out or a bank by processing payment or transfer Software or its elements don t need a graphical user interface to communicate with each other Software products exchange data and functionalities via a machine readable medium which can be likened to Application programming interfaces An API is a set of programming code that enables data transmission between one software product and another It also contains the terms of this data exchange Types of APIThere are severe types of APIs and some APIs are been made available base on their release policy API release policy could be Private Partner and Public For example with Javascript API you can perform an action like While the browser usually is above any code running in it a Mozilla derived API allows JavaScript limited access to browser settings Think about aspects such as reading the user s homepage how bookmarks are handled and where new tabs show up API release policy Private These APIs are solely used within an organization and In house developers use these APIs to integrate a company s IT systems or applications build new systems or customer facing apps leveraging existing systems The private strategy allows a company to fully control API usage Partner Openly promoted but available for known business partners who have signed an agreement with the publisher or the API company The common use case for partner APIs is software integration between two parties For example an e commerce platform like Timiun integrated a payment API develop and publish by Monify Public These types of APIs are publicly available to use like OAuth APIs from Google It has also not given any restriction to use them So they are also known as Public APIs APIs can be classified according to the systems for which they are designed There are Database APIs that enable communication between an application and a database management system working with databases by writing queries to access data change tables etc Web APIs provide machine readable data and functionality transfer between web based systems which represent client server architecture These APIs mainly deliver requests from web applications and responses from servers using Hypertext Transfer Protocol HTTP API SpecAn API spec is made up of a plan of how your API should look structurally like an architectural design of a product The best part of an API Spec is that it enables you to isolate design flaws or problems before you write a line of code The advantage that comes with planning your API specification is something worth the time put in Building your API base on specification could possibly add two or more weeks to the deadline for the development life cycle but it worth it The idea behind APIs is simple it should be flexible enough to be used by anyone and adequately documented to enter face with the developers using it Most time thinks of API having customer support where a developer could chat up the support about the difficulties s he could be facing integrating using the API but this is while we have Technical writers and Documentarians I supposed API DocsAPI documentation is a technical content deliverable containing instructions about how to effectively use and integrate with an API Swagger ioAs stated above API documentation is a company s customer support system for marketing their API so you understand how effective and the amount of effort that has been put out to have that ready for consumption Is easy to ready documentation but it is more fun when it is properly structured in a manner that a user can easily locate what s he is looking out for Most documentation teams while building the docs for their APIs are responsible for continuous maintenance of the documentation so they basically design means of getting feedback from users on how to improve the docs Once I heard someone saying if you don t document it then it didn t happen documentation is an art of credibility and reading documentation carefully is an art of consistency Thanks for reading	2021-04-17 17:43:48
海外TECH	DEV Community	Data visualization: Using amCharts in React.js with Mojo	https://dev.to/raigaurav/data-visualization-using-amcharts-in-react-js-with-mojo-29mh	Data visualization Using amCharts in React js with MojoIn my previous article I talked about using amCharts library with Perl Mojolicious Today we will looking at creating the similar chart with React js instead of plain JavaScript I will keep it short since we already talked about it previously and will be reusing most of the code There are ways we can use the react js Without JSX using tag With JSXJSX stand for JavaScript XML It allow you to easily write HTML in react For now we will take the baby step and start without JSX Creating the data configWe will use the exact same example as in previous article and try to create a multi line chart title Number of automobiles sold per day by manufacturer label domainAxis Date rangeAxis Numbers of automobiles sold data Date Honda Toyota Ford Renault Date Honda Toyota Ford Renault Date Honda Toyota Ford Renault Date Honda Toyota Ford Renault Creating the mojo appThe version I am using for this article is mojo generate app MojoReactAppThis command will generate a example application with proper directory structure for a MVC application and mentioned previously Now go inside the dir and try to run this app morbo script mojo appWeb application available at Open the browser and hit http localhost and you can see the welcome page The rest of step is exact similar to mention in Creating the mojo app section in previous article So I will not board you by repeating it again We will directly see the react part Adding React js to appWe will update the default html ep to include the react js lt DOCTYPE html gt lt html gt lt head gt lt meta charset utf gt lt title gt lt title gt lt title gt content head lt head gt lt body gt lt div gt content lt div gt lt script src umd react production min js crossorigin gt lt script gt lt script src umd react dom production min js crossorigin gt lt script gt content end lt body gt lt html gt We are using the production minified version You can also use the development version also for debugging purpose I have added react js on layout template as we will be using it all our web pages In multi line chart html ep layout default title Charts content for head gt begin lt link rel stylesheet type text css href css charts css gt end lt div id root gt lt div gt content for end gt begin javascript javascript javascript javascript js multi line chart js javascript begin var domContainer document getElementById root createMultiLineChart domContainer lt chart data gt end endWe are geeting the chart data form create multi line chart in lib MojoReactApp Controller Charts pm when the template get rendered Lets update the public js multi line chart js to make it a React Component use strict React without JSXconst e React createElement class MultiLineChart extends React Component constructor props super props this

XYChart this createChart chart this chart chart componentWillUnmount if this chart this chart dispose render return e div id this state chartId null function createMultiLineChart domContainer chartData ReactDOM render e MultiLineChart chartId chartdiv data chartData null domContainer We are calling the createMultiLineChart function from our template with parameters The main point to know here is the state and lifecycle functions componentDidMount and componentWillUnmount Since there are already plenty of documentation available I encourage you to look into it One of the place to learn the concept is react official docs State and LifecycleIf you look closely the rest of function definition is not much changes from the previous used javascript We just wrapped it in react The final directory structure is mojo react app ┣etc ┃┗input data json ┣lib ┃┣MojoReactApp ┃┃┣Controller ┃┃┃┗Charts pm ┃┃┗Model ┃┃┃┗Data pm ┃┗MojoReactApp pm ┣public ┃┣css ┃┃┗charts css ┃┗js ┃┃┗multi line chart

user perspective side nothing has changed you will see the same output as before As I mentioned before we will starting with baby step The usage of the above mentioned way is very limited You can use the react js without jsx when your scope is small where you have to make a website of few pages because here we are not using the full power of react To use the react js with full potential and unleash its power you have to use jsx We will be looking in to it our next article The above example is available at github Perl onion logo taken from hereMojolicious logo taken from hereReact logo
