海外TECH	DEV Community	How to keep a history of MQTT data with Node.js	https://dev.to/reductstore/how-to-keep-a-history-of-mqtt-data-with-nodejs-1kh6	How to keep a history of MQTT data with Node jsThe MQTT protocol is very popular in IoT applications It is a simple way to connect different data sourceswith your application by using a publish subscribe model Sometimes you may want to keep a history of your MQTT data touse it for model training diagnostics or metrics If your data sources provide different formats of data that cannot be interpreted as time series of floats ReductStore is what you need Let s make a simple MQTT application to see how it works PrerequisitesFor this usage example we have the following requirements Linux AMDDocker and Docker ComposeNodeJS gt If you re an Ubuntu user use this command to install the dependencies sudo apt get update sudo apt get install docker compose nodejs Run MQTT Broker and ReductStore with Docker ComposeThe easiest way to run the broker and the storage is to use Docker Compose So we should create a docker compose ymlfile in the example s folder with the services version services reduct storage image reductstore reductstore latest volumes data data ports mqtt broker image eclipse mosquitto ports Then run the configuration docker compose upDocker Compose downloaded the images and ran the containers Pay attention that we published ports for MQTTprotocol and for ReductStore HTTP API Write NodeJS scriptNow we re ready to make hands dirty with code Let s initialize the NPM package andinstall MQTT Client andJavaScript Client SDK npm init npm install save reduct js async mqtt When we have all the dependencies installed we can write the script const MQTT require async mqtt const Client require reduct js MQTT connectAsync tcp localhost then async mqttClient gt await mqttClient subscribe mqtt data const reductClient new Client http localhost const bucket await reductClient getOrCreateBucket mqtt mqttClient on message async topic msg gt const record await bucket beginWrite topic await record write msg console log Received message s from topic s is written msg topic catch error gt console error error Let s look at the code in detail First we have to connect to the MQTT broker and subscribe to a topic The topic namejust random string which producers should know In our case it is mqtt data MQTT connectAsync tcp localhost then async mqttClient gt await mqttClient subscribe mqtt data rest of code catch error gt console error error If the MQTT connection is successful we can start dealing with ReductStore To start writing data there we need abucket We create a bucket with the name mqtt or get an existing one const reductClient new Client http localhost const bucket await reductClient getOrCreateBucket mqtt The last step is to write the received message to the storage We must use a callbackfor event message to catch it Then we write the message to entry mqtt data mqttClient on message async topic msg gt const record await bucket beginWrite topic await record write msg console log Received message s from topic s was written data topic When we call bucket beginWrite we create an entry in the bucket if it doesn t exist yet Then we write data to theentry with the current timestamp Now our MQTT data is safe and sound in the storage and we can access them by usingthe same SDK Publish data to MQTT topicWhen you launch the script it does nothing because there is no data from MQTT You have to publish something to topicmqtt data I prefer to use mosquitto pub For Ubuntu users it is apart of the mosquitto clients package sudo apt get install mosquitto clients mosuitto pub t mqtt data m Hello world Getting data from ReductStoreNow you know how to get data from MQTT and write it to ReductStore but we need a little NodejS script to read the datafrom the storage const Client require reduct js const client new Client http localhost client getBucket mqtt then async bucket gt const record await bucket beginRead mqtt data console log Last record s await record readAsString Get data for lash hour const stopTime BigInt Date now const startTime stopTime n for await const record of bucket query mqtt data startTime stopTime const data await record read console log Found record s with timestamp d data record time catch error gt console error error To read the latest record in the entry is very easy const record await bucket beginRead mqtt data const data await record readAsString To take data for timeinterval we can use the query method It returns an async iterator so we can use for awaitloop to iterate over the records const stopTime BigInt Date now const startTime stopTime n for await const record of bucket query mqtt data startTime stopTime const data await record read console log Found record s with timestamp d data record time Pay attention the storage uses timestamps with microsecond precision so we can t use Date class and number type What is why we use BigInt ConclusionAs you can see the MQTT protocol and ReductStore very simple technologies that can be used together very easily inNodeJS You can find the source code of the example here If you have any questions or problems running it Feel free tomake an issue I hope this tutorial has been helpful Thanks LinksReductStoreJavaScript Client SDKMosquitto MQTT BrokerFull example on
