海外TECH	DEV Community	Storing Data with Dapr	https://dev.to/azure/storing-data-with-dapr-cd8	Storing Data with DaprDapr No not dapper dapr If you haven t read my past articles about dapr that s ok Let me try to boil this big project down to a sentence Dapr is a process you run that does all the hard stuff for your app you d rather not doIf you want to read more about it see the intro blog post And with that let s talk about and demo probably the hardest thing that most any apps have to deal with storing data ‍ ️Dapr does other things besides storage too Why It MattersDealing with data stores is hard You have to get the right SDK mock out your data store for unit tests write integration tests for round tripping data make sure you deal with migrations failover and more Dapr helps with all that but it also comes with some limitations too Before we go demo the thing some pros and cons for storage You read write data with a pretty simple REST API or gRPC You get a lot of useful features retries anyone You can swap out implementations Dapr comes with a bunch of different implementations of the data API across clouds and open closed source You have to fit your data model into key value Not all apps fit into this modeland You have to do a bit of reading to take advantage of some useful storage features Strong consistencyOptimistic ConcurrencyRetry policiesIn Dapr land the data storage API isn t called a database on purpose because it gives you a key value storage API It s not SQL or any other kind of rich query language so keep that in mind when deciding what to use If you want you can check out more details on storage here ‍ ️Surf s Up Let s Demo This ThingDapr comes with a bunch of different implementations of the data API across clouds and open closed source We ll use the Redis implementation here You ll need to have Docker installed and running for this demo to work ️⃣ Installing I followed the installing instructions using the Linux script since I m using WSL wget q O bin bashI had to provide my password because the script sudos things so if you re not into letting a random script from GitHub get superuser on your computer you can download binaries instead It was installed and I could test things out dapr help A serverless runtime for hyperscale distributed systemsUsage dapr command Available Commands components List all Dapr components configurations List all Dapr configurations help Help about any command init Setup dapr in Kubernetes or Standalone modes invoke Invokes a Dapr app with an optional payload deprecated use invokePost invokeGet Issue HTTP GET to Dapr app invokePost Issue HTTP POST to Dapr app with an optional payload list List all Dapr instances logs Gets Dapr sidecar logs for an app in Kubernetes mtls Check if mTLS is enabled in a Kubernetes cluster publish Publish an event to multiple consumers run Launches Dapr and optionally your app side by side status Shows the Dapr system services control plane health status stop Stops a running Dapr instance and its associated app uninstall Removes a Dapr installationFlags h help help for dapr version version for daprUse dapr command help for more information about a command It even has ascii art ️⃣Hello World Let s get something running The hello world tutorial actually goes much farther than I expected it would You get an app up and talking to the storage API backed by Redis but then you get a second app up and running and have it call an API on the first one It s actually showing off service invocation too I first got the hello world sample code git clone amp amp cd samples hello worldThe sample code has a Python app and a Node app Both has a REST API in them The Node App First the Node app The demo README first goes through the Node code a bit The really interesting bit I saw was that we re doing a POST request with the fetch API to the local Dapr API to store some data What was cool was you can also just return some JSON and it ll be automatically stored state key nomnomnom value pizza I really like that part because you don t have to manually do anything to get data into the database It just happens On to running the thing You do the standard thing to install the JS dependencies npm installnpm WARN node server No repository field added packages from contributors and audited packages in sfound vulnerabilities ╭ー╮ ││ │New patch version of npm available → │ │Changelog │ │Run npm install g npm to update │ ││ ╰ー╯But you then run it with the dapr CLI not npm or node This spits out a lot of log lines and that s normal Here s approximately what it looks like dapr run app id nodeapp app port port node app js️Starting Dapr with id nodeapp HTTP Port gRPC Port DAPR time T level info msg starting Dapr Runtime version commit ef dirty app id nodeapp instance DESKTOP DQPVM scope dapr runtime type log ver lt snip gt APP Node App listening on port DAPR time T level info msg application discovered on port app id nodeapp instance DESKTOP DQPVM scope dapr runtime type log ver lt snip gt ️Updating metadata for app command node app jsYou re up and running Both Dapr and your app logs will appear here Ok now it s running You use the dapr CLI to also make calls to the web service I like the simplicity of a single CLI dapr invoke app id nodeapp method neworder payload data orderId App invoked successfullyYou can also use curl for this if you wantAnd verifying that the request actually went through and the data was stored we have logs APP Got a new order Order ID APP Successfully persisted state And we can also call the Node App s API to get the new data back out of the datastore curl http localhost v invoke nodeapp method order orderId This and the above dapr invoke call are using one of the features in Dapr s service discovery building block The Python App Now for the grande finale The Python code calls the Node app in an infinite loop so we should be able to see the Node app responding to requests and also see the datastore fill up at the same time First we set up the Python dependency pip install requests lt snip gt Successfully installed certifi chardet idna requests urllib And then I ran it with the same dapr run command we used for the Node app except in a new terminal tab I cut out all the verbose log lines this time dapr run app id pythonapp python app py️Starting Dapr with id pythonapp HTTP Port gRPC Port ️Updating metadata for app command python app pyYou re up and running Both Dapr and your app logs will appear here Now back in the Node app logs storage is starting to fill up APP Got a new order Order ID APP Successfully persisted state APP Got a new order Order ID APP Successfully persisted state lt snip gt That s It From experience getting storage and microservice to microservice calls working from scratch takes time carefully crafted code and effort I wanted to compare this Node Python codebase to compare my experience and was pleasantly surprised Let s break it down lines of Node code including commentsWe could save a lot of lines if we returned the data JSON dictionary instead of using fetch calls lines of Node code including commentsFrom experience with Go I can say that a battle tested storage layer for this kind of thing would be about lines That s an apples to oranges comparison but I know for sure that all the battle tested bits are now behind that slick storage API the Node app is using And funny enough that part is written in Go P S don t forget to clean up dapr stop app id nodeapp amp amp dapr stop app id pythonapp Bonus Behind the ScenesI mentioned above that you need to have Docker installed in order to get this working That s all because Dapr needs an image running in the background for this demo to work cbad redis docker entrypoint s… weeks ago Up hours gt tcp dapr redisThe important one is Redis By default all the storage API calls the Node app is making get routed into Redis Wrap UpSo we ve seen the storage API and a bit of the service invocation API Honestly those two pieces alone can get you a long way just on basic usage alone As you get more advanced you ll probably want to learn more about and use things like concurrency management and retry policies Any way you go the docs repository and particularly the state management section are great references That s all for today I hope you go forth and enjoy dapr
