海外TECH	DEV Community	AWS open source newsletter, #161	https://dev.to/aws/aws-open-source-newsletter-161-59d8	AWS open source newsletter June th Instalment Welcome to of the AWS open source newsletter and another week for fresh new open source projects and code for you to practice your four freedoms This weeks projects include tools that will help you create temporary elevated credentials a new Java library that provides methods for encrypting and decrypting cryptographic materials an AWS DynamoDB wrapper for Node TypeScript developers and a solution to help you find and visualise data assets We also have some great demo code that shows you how you can deploy an AWS managed Active Directory Keycloak a tool to help automate the creation of transcripts for your prod casts and a great project that helps you to build continuous deployment pipelines following current good practices This weeks newsletter is also filled with lovely content on some of your favourite open source projects featuring Falcon Keycloak Cedar FreeRTOS Apache Airflow Apache Spark Apache Hudi Apache Iceberg and Delta Lake Apache Flink OpenChatkit Pinniped Kubecost Karpenter ONNX Apache Kafka Babelfish for Aurora PostgreSQL AWS Amplify Next js OpenSearch Flux ArgoCD KVM and more I have added a few events that are happening this week and next so make sure you do not miss those too FeedbackBefore you dive in however I need your help Please please please take minute to complete this short survey and bask in the warmth of having helped improve how we support open source Celebrating open source contributorsThe articles and projects shared in this newsletter are only possible thanks to the many contributors in open source I would like to shout out and thank those folks who really do power open source and enable us all to learn and build on top of what they have created So thank you to the following open source heroes David Krohn Marcell Jobs Nicholas Saenz Julienne Anel Orazgaliyeva Carlos Santana Sai Vennam Suraj Narwade James McIntyre Siva Guruvareddiar Elamaran Shanmugam Re Alvarez Parmar Adam McLean Ashok Srirama Hemanth AVS Giacomo Margaria Lotfi Mouhib Hamza Mimi Vikram Elango Andrew Smith Dhawalkumar Patel Nir Tsruya and Ankit Gupta Daniel Arenhage Kalaiarasu M Shana Schipers Ian Meyers Carlos Rodrigues Damon Cortesi Vincent Beck Tony Smith Darin McAdams Daniel Bass Lee Gilmore and Johannes Koch Latest open source projectsThe great thing about open source projects is that you can review the source code If you like the look of these projects make sure you that take a look at the code and if it is useful to you get in touch with the maintainer to provide feedback suggestions or even submit a contribution Toolsiam identity center teamiam identity center team this repository contains the source code for the deploying temporary elevated access management TEAM application TEAM is an open source solution that integrates with AWS IAM Identity Center and allows you to manage and monitor time bound elevated access to your multi account AWS environment at scale The solution is a custom application that allows users to request access to an AWS account only when it is needed and only for a specific period of time Once the time period has elapsed elevated access is automatically removed Very nice project with great documentation aws cryptographic material providers library javaaws cryptographic material providers library java provides methods for encrypting and decrypting cryptographic materials used in higher level client side encryption libraries The AWS Cryptographic Material Providers Library abstracts lower level cryptographic materials management of encryption and decryption materials It uses cryptographic best practices to protect the data keys that protect your data The data key is protected with a key encryption key called a wrapping key or master key The encryption method returns the data key and one or more encrypted data keys Supported libraries use this information to perform envelope encryption The data key is used to protect your data and the encrypted data keys are stored alongside your data so you don t need to keep track of the data keys separately You can use AWS KMS keys in AWS Key Management Service AWS KMS as wrapping keys The AWS Cryptographic Material Providers Library also provides APIs to define and use wrapping keys from other key providers Note The AWS Cryptographic Material Providers Library is released as a developer preview and is subject to change The current release is not intended to be used in production environments tinymotinymo is a nice AWS DynamoDB wrapper for Node TypeScript developers It simplifies constructing DynamoDB s JSON based command inputs within your code and should make the experience a lot less annoying Repo has plenty of examples to get you started too cdk aws ad connectcdk aws ad connect from AWS Community Builder and Ambassador David Krohn and Marcell Jobs that makes it easy to deploy and configure an Active Directory Connector using AWS Step Functions sensitive data protection on awssensitive data protection on aws this solution allows enterprise customers

海外TECH	DEV Community	Good practices and Design Patterns for Vue Composables	https://dev.to/jacobandrewsky/good-practices-and-design-patterns-for-vue-composables-24lk	Good practices and Design Patterns for Vue ComposablesI recently had a great discussion with my team at Vue Storefront about patterns for writing Vue composables In the case of our system composables are responsible for storing the main business logic like calculations actions processess so they are a crucial part of the application Unfortunately over the time we didn t have that much time to create some sort of Contract for writing Composables and because of that few of our composables are not really composables I am really happy that right now we have this time to refactor our approach to building new composables so that they are maintainable easy to test and actually useful In this article I will summarise ideas that we have created and also merge them with good practices and design patterns that I read about in few articles So this article will be divided into three sections General Design PatternsMy recommendationsFurther readingEnjoy and also let me know what patterns and practices you are using in your projects General Design PatternsThe best source in my opinion to learn about patterns for building composables is actually a Vue js Documentation that you can check out here Basic ComposableVue documentation shows following example of a useMouse composable mouse jsimport ref onMounted onUnmounted from vue by convention composable function names start with use export function useMouse state encapsulated and managed by the composable const x ref const y ref a composable can update its managed state over time function update event x value event pageX y value event pageY a composable can also hook into its owner component s lifecycle to setup and teardown side effects onMounted gt window addEventListener mousemove update onUnmounted gt window removeEventListener mousemove update expose managed state as return value return x y That can be later used in the component like following lt script setup gt import useMouse from mouse js const x y useMouse lt script gt lt template gt Mouse position is at x y lt template gt Async composablesFor fetching data Vue recommends following composable structure import ref watchEffect toValue from vue export function useFetch url const data ref null const error ref null watchEffect gt reset state before fetching data value null error value null toValue unwraps potential refs or getters fetch toValue url then res gt res json then json gt data value json catch err gt error value err return data error That can be then used in the component like following lt script setup gt import useFetch from fetch js const data error useFetch lt script gt Composables contractBased on the examples above here is the contract that all composables should follow Composable file names should start with use for example useSomeAmazingFeature tsIt can accept input arguments that can be primitive types like strings or can accept refs and getters but it requires to use toValue helperComposable should return a ref value that can be accessed after destructuring the composable like const x y useMouse Composables can hold global state that can be access and modified across the app Composable can cause side effects such as adding window event listeners but they should be cleaned when the component is unmounted Composables should only be called in lt script setup gt or the setup hook They should also be called synchronously in these contexts In some cases you can also call them in lifecycle hooks like onMounted Composables can call other composables inside Composables should wrap certain logic inside and when too complex they should be extracted into separate composables for easier testing My recommendationsI have built multiple composables for my work projects and Open Source projects NuxtAlgolia NuxtCloudinary NuxtMedusa so based on these I would like to add few points to the contract above that are based on my experience Stateful or and pure functions ComposablesAt certain point of code standarization you may come into a conclusion that you would like to make a decision about the state hold in the composables The easiest functions to test are those who do not store any state i e they are simple input output functions for example a composable that would be responsible for converting bytes to human readable value It accepts a value and returns a different value it doesn t store any state Don t get me wrong you don t have to make a decision OR You can completely keep both stateful and stateless composables But this should be a written decision so that it is easier to work with them later on Unit tests for ComposablesWe wanted to implement unit tests with Vitest for our Frontend application When working in the backend having unit tests code coverage is really useful because there you mainly focus on the logic However on the frontend you usually work with visuals Because of that we decided that unit testing whole components may not be the best idea because we will be basically unit testing the framework itself if a button was pressed check if a state changed or modal opened Thanks to the fact that we have moved all the business logic inside the composables which are basically TypeScript functions they are very easy to test with Vitest and allows us also to have more stable system Scope of ComposablesSome time ago in VueStorefront we have developed our own approach to composables way before they were actually called like that actually In our approach we have beed using composables to map business domain of E Commerce like following const cart load addItem removeItem remove useCart This approach was definitely useful as it allowed to wrap the domain in one function And in the simpler examples such as useProduct or useCategory this was relatively simple to implement and maintain However as you can see here with the example of useCart when wrapping a domain that contains much more logic than just data fetching this composable was growing into a shape that was really difficult to develop and maintain At this point I started contributing into Nuxt ecosystem where different approach was introduced In this new approach each composable is responsible for one thing only So instead of building a huge useCart composable the idea is to build composables for each functionality i e useAddToCart useFetchCart useRemovefromCart etc Thanks to that it should be much easier to maintain and test these composables Further readingThat will be all from my research If you would like to learn more about this topic make sure to check out the following articles	2023-06-19 07:11:53
