海外TECH	DEV Community	How to build AdonisJS API to store your Raspberry Pi Temperature	https://dev.to/bobbyiliev/how-to-build-adonisjs-api-to-store-your-raspberry-pi-temperature-5c6a	How to build AdonisJS API to store your Raspberry Pi Temperature IntroductionI have a few Raspberry Pi devices at home and I wanted to be able to collect the data from their temperature sensors on a regular interval and store that data in a Postgres database Later on I could use that data for some analytics together with Materialize In this tutorial we will use AdonisJS to build a simple API that will collect the data from the sensors and store it in a Postgres database as shown in the following image This can be used to collect the temperature data of a large number of Raspberry Pi devices PrerequisitesBefore you get started you would need to make sure that you have the following installed Install Node jsInstall Postgres What is AdonisJSAdonisJS is a Node js framework that is used to create RESTful APIs along with full stack web applications It is a great tool to build web applications that can be deployed to any platform It feels a lot like Laravel but it is based on Node js rather than PHP If you are not familiar with AdonisJS no worries you would still be able to follow along However if you want to learn more about AdonisJS make sure to check out this tutorial here AdonisJS for Beginners How to install AdonisJSTo install AdonisJS you would need to run the following command npm init adonis ts app latest raspberry pi adonisjs appOnce you run that you will be asked to select a project structure You will be able to choose between an API Web App and a minimal possible AdonisJS app CUSTOMIZE PROJECT❯Select the project structure …Press lt ENTER gt to select❯api Tailored for creating a REST API server web Traditional web application with server rendered templates slim A smallest possible AdonisJS application For this tutorial let s go with the API option Using your arrow keys select web and hit enter After that you will be asked to choose a name for the project I will leave this as raspberry pi adonisjs app but feel free to choose a different name I will then press enter and say yes to the rest of the settings ❯Enter the project name ·raspberry pi adonisjs app❯Setup eslint y N ·y❯Configure webpack encore for compiling front end assets y N ›yOnce that is done you can switch to the new project directory cd raspberry pi adonisjs appAnd once in there start the webserver node ace serve watchThe ace command is very similar to the artisan command in Laravel It is a command line interface for running AdonisJS commands The node ace serve command will start the webserver and watch for changes to your code To check all of the ace commands you can run node ace Installing LucidSimilar to Laravel Eloquent AdonisJS provides an ORM The ORL is called Lucid and we will be using it today Lucid comes with an Active Record ORM Query Builder Migrations Seeds and Factories To install Lucid run the following command npm i adonisjs lucidOnce done you would need to do a quick configuration Configuring LucidIn order to configure Lucid you need to run the following ace command node ace configure adonisjs lucidYou will be asked to select the database driver that you want to use Here make sure to select PostgreSQL Next you will be asked to select where you want to display the configuration instructions I chose In the terminal which prints out the necessary environment variables that you have to add to your envfile Make sure to update the DB DATABASE and DB USERNAME and DB PASSWORD variables in your env file accordingly so that you can connect to your database Add a mode and a migrationTo add a model and a migration run the following command node ace make model Sensor mThis will create a new model and a migration CREATE database migrations sensors tsCREATE app Models Sensor tsOpen the migration file and update the file so that it looks like this import BaseSchema from ioc Adonis Lucid Schema export default class Sensors extends BaseSchema protected tableName sensors public async up this schema createTable this tableName table gt table increments id table string device table string temperature table string timestamp Uses timestamptz for PostgreSQL and DATETIME for MSSQL table timestamp created at useTz true table timestamp updated at useTz true public async down this schema dropTable this tableName We basically added extra columns that will store the name of the device the temperature and the timestamp when the data was recorded To run the migration run the following command node ace migration runThis will create the sensors table in your database with the columns we specified Creating a ControllerNext we will create a controller This is where we will add the functionality that will allow us to store the Raspberry Pi data in our Postgres database Again we will be using the ace command to create a new controller node ace make controller SensorsControllerThis will create a controller file at app Controllers Http SensorsController tsNext let s create the routes that we would need Adding our methodsAs we are going to use this API to store the data from our Raspberry Pi devices we will add just a single method to our controller With your favorite text editor open the SensorsController ts file and add the following method import Route from ioc Adonis Core Route import Database from ioc Adonis Lucid Database import HttpContextContract from ioc Adonis Core HttpContext export default class SensorsController public async store request let name raspberry if request qs name null name request qs name let timestamp if request qs timestamp null timestamp request qs timestamp let temperature if request qs temperature null temperature request qs temperature console log name timestamp temperature await Database insertQuery table sensors insert device name timestamp timestamp temperature temperature return message Successfully added sensor data There are a few things to note here The import statement is importing the Route and Database from the ioc Adonis Core Route and ioc Adonis Lucid Database packages The await keyword is used to wait for the database query to finish The request qs method is used to get the query string parameters from the request That way we will be able to get the name timestamp and temperature sent by the Raspberry Pi devices Creating the AdonisJS routesYour routes file is stored at start routes ts In there we can specify our application URLs and map them to different controllers and methods We do not yet have the methods ready but we know that we would need the following routes GET temperature This route will store the data sent by the Raspberry Pi devices Open your routes file at start routes ts and update it so that it has the following content import Route from ioc Adonis Core Route Route get temperature SensorsController store Adding authenticationFor the sake of this tutorial I would not be implementing a full blown authentication as the API would be running locally on my network and would not have any sensitive data However if you want to take this one step further you can follow the steps from the documentation here on how to implement this AdonisJS Authentication Docs Adding cron jobs to the Raspberry Pi devicesNow that we have our controller and routes we can add a cron job to the Raspberry Pi devices which will send the data to the API and store it in our database Let s create a small bash script which we will run every minute bin bash AdonisJS API URL Make sure to change this to your API URLapi url http localhost temperature Specify the name of the Raspberry Pi device name raspberry if z NAME then name raspberry fi Get the temperature from the Raspberry Pi device function temperature temperature opt vc bin vcgencmd measure temp tr d temp C echo temperature Get the current timefunction timestamp time date s echo time echo name timestamp temperature curl X GET api url name name i amp timestamp timestamp amp temperature temperature Make sure to change the URL to your AdonisJS API If you are running this on the same Raspbery Pi you can leave it as localhost if not you could use the IP of the device that you are running the API on Save the script as temperature sh and make it executable chmod x temperature shThen edit your crontab sudo crontab eAdd the following line to your crontab home pi temperature shThis will run the script every minute and send the data to the API ConclusionYou can find the code for this tutorial here AdonisJS API Raspberry Pi TemperatureAs the second part of this tutorial we will use Materialize to run streaming SQL queries on the data collected by the API We are going to build the following setup If you want to learn more about AdonisJS I could suggest checking out this tutorial here Building a real time web application with Materialize and AdonisJSТоlearn more about Materialize make sure to check out this tutorial here Learn Materialize by running streaming SQL on your nginx logsHope that this helps	2021-12-19 10:32:01
