海外TECH	DEV Community	SQL Server to React in 60 Seconds With Prisma	https://dev.to/jonrcrowell/sql-server-to-react-in-60-seconds-with-prisma-16fj	SQL Server to React in Seconds With PrismaPreviously published at fullstackfish comConnecting SQL Server to React with Prisma is a straightforward and satisfying experience This post will guide you through the process of getting your Azure SQL Server data onto a screen in a React app in less than a minute Really As long as you pause your timer while npm is downloading files Of course there are a few prerequisites before you can get it connected that quickly Prisma supports working with existing databases which we are doing in this post as well as defining the database in your app and then creating the database objects through migrations which will be covered in other posts You must have an existing Azure SQL Server with a database that you have credentials for You must also have your ip whitelisted in Azure The database must have at least one table with data that we can query You must have up to date versions of Node js or higher and Visual Studio Code installed See nvm is for barbarians Manage Node versions with Volta instead for a great way to manage Node versions You must have create next app installed globally npm global install create next app if you don t You must have an empty folder on your hard drive for this project And that s it Let s do this Open your empty project folder in VS CodeOpen a terminal and run the following command to initialize a new next app npx create next app The dot will create the next app in the current path Once the app is initialized you should see a confirmation Run the app to verify it compiles and runs correctly npm run devOpen http localhost in a browser to verify Now stop the app and let s get some data You ll need to add the following dependencies prisma as a dev dependency and prisma client as a regular dependency npm i D prismanpm i prisma clientCheck your package json file to verify that you have version or greater of prisma in the dev dependencies Initialize prisma in your app This will add a prisma folder in root with a schema prisma file It will also add a env file if you don t already have one which you shouldn t at this point For future reference if you do have a env file this step will add a new entry into the file without harming anything else you may have in there npx prisma initThe default connection that is configured in the schema prisma file is for Postgres Let s fix that Edit the file to look like this schema prismagenerator client provider prisma client js datasource db provider sqlserver url env DATABASE URL Note the constant DATABASE URL that is referenced We ll update the value of that constant in the env file now Set the connection string in the env file to point to your Azure SQL Server database I m using a username and password for this example Explaining all the variations on connection strings is beyond the scope of this post but I m assuming you can figure that out My connection string with the sensitive bits masked to protect the innocent DATABASE URL sqlserver SERVERNAME database windows net database DATABASENAME encrypt true trustServerCertificate false hostNameInCertificate database windows net loginTimeout user USERNAME password PASSWORD Connection strings can be long so you ll have to scroll to the right to see the whole thing Now we re ready to introspect the database This step will populate the Prisma schema based on your database schema Make sure you have your schema prisma file open before you run the following It s fun to watch the magic happen npx prisma db pullBoom Our app and database are now friends Assuming your connection string is correct and you have access to your database you should now see a list of all the tables in the dbo schema generated as models in your schema prisma file This functionality is currently limited to tables in the dbo schema You won t have views or functions or stored procs in the schema file which is true for all databases Prisma works with so don t get your SQL Server feelings hurt You can still interact with those objects in your app Now that we have a valid schema let s run the command to generate the Prisma client npx prisma generateNext is a fabulous tool that keeps your backend and frontend code safely separate but extremely easy to work with in the same project among many other benefits Add a lib folder in root with a prisma js file and copy paste or type the following into that file lib prisma jsimport PrismaClient from prisma client let prisma if process env NODE ENV production prisma new PrismaClient else if global prisma global prisma new PrismaClient prisma global prisma export default prisma This is the best practice defined by Prisma and Next for the integration You ll be able to import a single instance of the prisma client throughout your app something we ll do shortly which will handle connection pools for you and protect you from memory leaks See Best practice for instantiating PrismaClient with Next js for more details Let s define an API route that our front end will consume Add a file in pages api called products js Replace products with whatever table you want to work with from your database I m using Adventure Works for this example Add this to the products js pages api products jsimport prisma from lib prisma export default async function handle req res const products await prisma product findMany res json products Now delete the contents of the pages index js file and replace it with the following as a guide You ll need to use your React skills to create a component that incorporates your data You ll need to replace products with whatever table you want from your database and use fields from that table instead of the ones I m using below pages index jsexport const getServerSideProps async gt const res await fetch http localhost api products const products await res json return props products export default function Product products return lt div gt products map p gt return lt div key p ProductID gt lt p gt p Name ー p ListPrice lt p gt lt div gt lt div gt That s it Let s see if it worked npm run devOpen http localhost in a browser and behold your data Hit me up on twitter jonrcrowell to let me know what you think or if you ran into any issues Prisma

GCP	Cloud Blog	Service orchestration on Google Cloud	https://cloud.google.com/blog/topics/developers-practitioners/service-orchestration-google-cloud/	Service orchestration on Google CloudGoing from a monolithic architecture to microservices has clear benefits including reusability scalability and ease of change Most of the time business problems are solved by coordinating multiple microservices This coordination is based on event driven architectures which can be implemented via two approaches choreography and orchestration Click to enlargeService choreography and service orchestrationService Choreography  With service choreography each service works independently and interacts with other services in a loosely coupled way through events Loosely coupled events can be changed and scaled independently which means there is no single point of failure But so many events flying around between services makes it quite hard to monitor Business logic is distributed and spans across multiple services so there is no single central place to go for troubleshooting There s no central source of truth to understand the system Understanding updating and troubleshooting are all distributedService Orchestration To handle the monitoring challenges of choreography developers need to bring structure to the flow of events while retaining the loosely coupled nature of event driven services Using service orchestration the services interact with each other via a central orchestrator that controls all interactions between the services This orchestrator provides a high level view of the business processes to track execution and troubleshoot issues In Google Cloud  Workflows handles service orchestration  Once you have decided between the two approaches for your application design questions are largely about the characteristics of the services and the use case You should prefer orchestration within the bounded context of a microservice but prefer choreography between bounded contexts That is you ll likely have choreography at a higher level with orchestration at lower levels both in the same system Google Cloud provides services supporting both orchestration and choreography approaches Pub Sub and Eventarc are both suited for choreography of event driven services whereas Workflows is suited for centrally orchestrated services  Google Cloud support for service orchestration Workflows Workflows is a service to orchestrate and automate Google Cloud and HTTP based API services with serverless workflows It is a fully managed scalable and observable way to define a business process and orchestrate calls to several services Workflow calls those services as simple web APIs Using Workflows you can define the flow of your business logic in a YAML based workflow definition language and use the UI or API to trigger the workflow You can use Workflows to automate complex processes including event driven and batch jobs error handling logic sequences of operations and more  Workflows is particularly helpful with Google Cloud services that perform long running operations as Workflows will wait for them to complete even if they take hours With callbacks Workflows can wait for external events for days or months Google Cloud support for service choreographyPub SubPub Sub enables services to communicate asynchronously with latencies on the order of milliseconds Pub Sub is used for messaging oriented middleware for service integration or as a queue to parallelize tasks Publishers send events to the Pub Sub service without regard to how or when these events will be processed Pub Sub then delivers events to all services that need to react to them Subscribers Pub Sub is also used for streaming analytics and data integration pipelines to ingest and distribute data as covered in the Data Analytics post  Eventarc Eventarc enables you to build event driven architectures without having to implement customize or maintain the underlying infrastructure It offers a standardized solution to manage the flow of state changes also known as events between decoupled microservices Eventarc routes these events to Cloud Run while managing delivery security authorization observability and error handling for you Eventarc provides an easy way to receive events not only from Pub Sub topics but from a number of Google Cloud sources with its Audit Log and Pub Sub integration Any service with Audit Log integration or any application that can send a message to a Pub Sub topic can be event sources for Eventarc  Additional services that help with both choreography and orchestrationCloud TasksCloud Tasks lets you separate out pieces of work that can be performed independently outside of your main application flow and send them off to be processed asynchronously using handlers that you create These independent pieces of work are called tasks Cloud Tasks helps speed user response times by delegating potentially slow background operations like database updates to a worker It can also help smooth traffic spikes by removing non user facing tasks from the main user flow   Difference between Pub Sub and Cloud Tasks Pub Sub supports implicit invocation a publisher implicitly causes the subscribers to execute by publishing an event Cloud Tasks is aimed at explicit invocation where the publisher retains full control of execution including specifying an endpoint where each message is to be delivered Unlike Pub Sub Cloud Tasks provides tools for queue and task management including scheduling specific delivery times rate controls retries and deduplication Cloud SchedulerWith Cloud Scheduler you set up scheduled units of work to be executed at defined times or regular intervals commonly known as
