海外TECH	DEV Community	You just need URL() instead of URLSearchParams() for query params	https://dev.to/basharath/you-just-need-url-instead-of-urlsearchparams-for-query-params-2od1	You just need URL instead of URLSearchParams for query paramsReading and manipulating URLs or query strings is involved in various applications for obtaining data from requests and routing users or requests Different languages have different ways to deal with query parameters or routing at the backend  In this article we re going to look at the ways to read and manipulate query strings and URLs using URL and URLSearchParams APIs of Javascript at the client or more specifically in the browser In the browser there s a global variable called location or window location using which we can get various details about the URL of your active browser tab Using location property we can get details like full URL protocol host hostname port pathname search params as a string etcBut to parse and read any URL other than our active tab address we have URL and URLSearchParams APIs at our disposal in JavaScript  Let s get into more details of these JavaScript APIs How to use URL API in JS A URL constructor is used to construct normalize parse and encode URLs It provides various properties to read and manipulate the components of a URL URL takes an absolute URL string as an argument and returns an object with various properties to read and manipulate the passed URL  Let s understand this URL by using a sample URL with query params const parsedUrl new URL Smith amp age amp id console log parsedUrl age amp id In the above code we can see that URL could parse the supplied URL string correctly The parsedUrl can be used as a string directly anywhere we want or we can use the various properties and methods attached to it by the URL class URL has got most of the properties similar to the window location object which includes host hostname href origin port protocol search searchParams username password etc  const url new URL blog name John Smith amp age amp id heading url host example com url hostname example comurl href blog name John Smith amp age amp id headingurl origin url pathname blog url port url protocol https url hash headingurl search name John Smith amp age amp id url searchParams URLSearchParams So by using URL API we can get various types of info about the URL link that we pass If you observe the prop url searchparams is actually returning the URLSearchParams which we are going to see in the next section In certain URLs we have username and password in the URL itself and such URLs can be parsed easily to get username and password details using this URL API const newUrl new URL https john somePass dev example com api test console log newUrl username johnconsole log newUrl password somePassTo modify any of the props we can just simply assign any valid value to it  const url new URL blog name John Smith amp age amp id heading url href url pathname about url hash important url search name Bond amp age console log url age importanturl origin Error Cannot set property originYou can set or modify any of the properties of url except origin and searchParams if you try an error will be thrown   How to use URLSearchParams in JS In the last section we have seen the ways to read and modify URLs but reading and setting individual URL query strings can be done easily using the URLSearchParams constructor  URLSearchParams takes the query string of a URL as argument and returns an iterable object with various methods to read and manipulate the query parameters If you pass a full URL to the URLSearchParams it will clip off the inital param after So it s always good to pass only the query string part of the URL or just pass query string as an object with key value pairs const link age amp id amp name smith const url new URL link const searchParams new URLSearchParams url search For active browser link use location searchsearchParams get name johnsearchParams getAll name john smith searchParams has age truesearchParams toString name john amp age amp id amp name smithsearchParams append place Munich Adding a new query paramsearchParams set id Updating the id to searchParams toString name john amp age amp id amp name smith amp place MunichsearchParams delete place searchParams toString name john amp age amp id amp name smithThere are other methods like keys values entries and forEach iterates over the values to iterate the search params  Other than forEach method all return iterables so array methods like forEach can t be run on those We need to convert them to an array and use methods like forEach map etc  const searchParams new URLSearchParams name john amp age amp id searchParams forEach v gt console log v john Array from searchParams keys forEach k gt console log k name age idArray from searchParams values forEach v gt console log v john Object fromEntries searchParams entries name john age id In the above code snippet for the methods keys values and entries we converted them to arrays and object to see the results Now if we go back to the URL API methods we have searchParams method there using that we can get all the details that we could get using URLSearchParams except that we cannot set any query parameters from there  const url new URL Smith amp age amp id url searchParams get name John Smithurl searchParams has age trueurl searchParams toString name John Smith amp age amp id url searchParams forEach i gt console log i John Smith Object fromEntries url searchParams entries name John Smith age id Using URL we can pass full URL address and can still read the correct query params unlike URLSearchParams where we need to pass only the query string to read the correct query parameters data So that s all about URL and URLSearchParams in Javascript In conclusion what we can infer is in most of the cases to read the query strings we you just need to use URL API If you liked this article

really need to know about Make sure you sign up for it so you do not miss a thing Quick updatesAWS SAM CliLast week we announced the general availability of AWS Serverless Application Model CLI AWS SAM CLI support for local testing of AWS Cloud Development Kit applications AWS SAM and AWS CDK are both open source frameworks for building applications using infrastructure as code IaC AWS SAM is made up of the SAM template which is a way to describe infrastructure in an application using JSON or YAML and SAM CLI which is a tool to build package test and deploy AWS SAM applications AWS CDK is a development framework to define your cloud application resources using familiar programming languages such as Python or Node js Before this announcement you could use the AWS SAM CLI to build test and package serverless applications defined using AWS CloudFormation or AWS SAM templates With this release you can use AWS SAM CLI to run local testing on Lambda functions and REST APIs on API Gateway defined using the AWS CDK NodeJSAWS Lambda functions using the Node js runtime now support code packaged as ECMAScript modules allowing Lambda customers to consume a wider range of JavaScript packages in their Lambda functions In addition Lambda customers can now take advantage of top level await a Node js language feature When used with Provisioned Concurrency this improves cold start performance for functions with asynchronous initialisation tasks For more information see the blog post Using Node JS ES Modules and Top Level Await in AWS Lambda ECMAScript ES modules are a packaging format for JavaScript code used to publish JavaScript code libraries so they can be imported and re used in other applications Until now Lambda s Node js runtimes only supported code using the earlier CommonJS packaging format With this release customers can use the ES module format for both their function handler and any code they import With this release customers can also use top level await a Node js language feature to wait for asynchronous initialisation tasks to complete during the function initialisation phase This capability is especially useful for functions configured with Provisioned Concurrency which creates runtime environments ahead of time This is designed to reduce cold start latency resulting in more responsive applications Customers can use ES modules and top level await with all Lambda functions using the Node js runtime and subsequent releases of newer Node js runtimes Apache KafkaAmazon Managed Streaming for Apache Kafka Amazon MSK now supports Apache Kafka versions and for new and existing clusters These new Apache Kafka releases includes security improvements and bug fixes Apache HudiApache Hudi is an open source transactional data lake framework that greatly simplifies incremental data processing and data pipeline development by providing record level insert update and delete capabilities This record level capability is helpful if you re building your data lakes on Amazon Simple Storage Service Amazon S or Hadoop Distributed File System HDFS In this post New features from Apache Hudi and available on Amazon EMR Udit Mehrotra and Gagan Brahmi share a summary of some of the key new features and capabilities included since Apache Hudi release versions and Amazon EMR on EKSAmazon EMR on EKS enables customers to easily run open source big data frameworks such as Apache Spark on Amazon EKS Amazon EMR on EKS customers setup and use a managed endpoint available in preview to run interactive workloads using integrated development environments IDE such as EMR Studio Data scientists and data analysts may need to use libraries in their code that are not available in the public distribution of Amazon EMR on EKS Spark runtime Customers use custom images functionality to create Spark driver and executor images that contain their application dependencies Until now customers who used Amazon EMR on EKS managed endpoints to run interactive workloads were unable to use custom images With this release you can now build a custom image with your application dependencies and use the image in your interactive jobs run using managed endpoints You can also use the Custom Images feature to customise container images for AWS Graviton based instances Customers often have applications with different compute architecture requirements For example customers may want to run machine learning workloads on AWS Graviton ARM based instances that offer compelling price performance benefits while running daily data transformation jobs on non Graviton based instances Previously Amazon EMR on EKS users could only customise container images of non Graviton based EC instances With this release users can customise images for both Graviton based and non Graviton based EC instances Building deploying and using container images for different architectures from the same image repository in Amazon EMR on EKS is now more simple KubernetesAmazon Elastic Kubernetes Service EKS now supports IPv enabling customers to scale containerised applications on Kubernetes far beyond limits of private IPv address space while achieving high network bandwidth with minimal complexity Kubernetes uses a flat networking model that requires each pod to receive an IP address This simplified approach enables low friction porting of applications from virtual machines to containers but requires a significant amount of IP addresses that many private IPv networks are not equipped to handle Further clusters running in IPv based networks require complex network routing configuration to enable pod communication with internet services With EKS support for IPv pods are assigned only a globally routable IPv address and you easily scale applications in your cluster without consuming limited private IPv address space This globally routable IPv address can be used to directly communicate with any IPv endpoint in your Amazon VPC on premises network or the public internet IPv support is enabled through the Amazon VPC CNI plugin which directly integrates with the EC networking stack to deliver high performance and reliability With native VPC integration you can secure your applications using standard components including egress only internet gateways security groups and network access control lists ACL EKS configures networking so that pods can still communicate with IPv based endpoints outside the cluster enabling you to adopt the benefits of IPv and Kubernetes without requiring that all dependent services deployed across your organisation are first migrated to IPv Read more in the post from Sébastien Stormacq Amazon Elastic Kubernetes Service Adds IPv Networking Videos of the weekElectricEyeI missed this session from Jonathan Rao due to over reaching myself so happy that I was able to check it out on YouTube With continual increase of adoption of public cloud workloads and the expansion of services therein security and developer teams have a hard time keeping up with best practices of configurations While the cloud service providers and commercial partners have helped bridge the gap with Cloud Security Posture Management CSPM teams are still left in the dark with not often used or newly launched services Adopting Open Source Security tools can help bridge these gaps extend current coverage and further empower developer and security teams to detect issues before they become security incidents Watch this YT video to see Jonathan do a demo of ElectricEye and open source AWS CSPM tool with over available checks and support services which can help with extending your CSPM AWS DeepRacerChris Miller shows you how you can learn to code create and collaborate with a global

to inspire endless possibilities for programming your AWS DeepRacer device Apache LuceneAnother video from re Invent this time Michael Sokolov and Michael Froh take a look at the inner workings of modern open source development by following a significant complex change from inception to release In Amazon completed a multiyear migration of its customer facing product search engine onto a new service based on Apache Lucene supported by many AWS services In production Amazon observed Lucene s segmented nature influencing query latency and had an idea to reduce its segment count The idea seemed simple but its realisation through close collaboration with the Lucene developer community took nearly a year This session dives deep into this journey Events for your diaryIf you have an event
