海外TECH	DEV Community	Crunch Pokemon Data with Python and Deta Base	https://dev.to/ramko9999/crunch-pokemon-data-with-python-and-deta-base-2p	Crunch Pokemon Data with Python and Deta Base Crunch Pokemon Data with Python and Deta Base Setup and work on a datastore faster than PikachuThis article was originally posted on Medium If you prefer reading it from there please do check it out IntroductionPerformance is a must when it comes to building software However in certain situations the speed to set up and integrate new services for proof of concept evaluation or infrastructure is overlooked Specifically in the realm of databases there are many options but I find Deta to be most seamless to set up and use Deta offers Deta Base I will refer to it as Base a NoSQL data store optimized for developer simplicity In this article I aim to show how to set up a Deta project and interact with your Base to store and manipulate Pokemon data Let s get started AgendaSetupCRUDQuerying SetupTo begin navigate to Sign Up create a new account and verify your account Once you sign in you should be on the following page Click the arrow in the top left we will create a new project from scratch Enter a name of your choice and hit create A popup with your project key and project id will appear Make sure you save the key With the project key saved create a new directory walk into it and run the following command pip install flask detaFlask is a web framework that we will use to create endpoints to listen to incoming requests Based on the requests we will interact with our remote database using the deta package Here is how the folder structure will look like app pyconfig pyIn config py we will store our project keyDETA KEY YOUR COPIED KEY In our project we will create a Base called pokemon and utilize it to store access and manipulate Pokemon data Before that let s go over the schema for a record in pokemon Each record in a Base must correspond to a unique identifier called key When we insert a Pokemon record into our Base we will provide name as our key As a result if we needed to get information on Charizard we just have to ask pokemon to find the associated record with Charizard as its key In app py let s set up the Flask app and our connection to our Base pokemon from config import DETA KEY from flask import Flask request from deta import Deta from json decoder import JSONDecoder app Flask name deta project Deta DETA KEY db deta project Base pokemon decoder JSONDecoder if name main app run All the data access and manipulations will occur through db Our setup is now complete Onto the CRUD CRUDCRUD is an acronym for creating reading updating and deleting data in a database We will explore how to perform each of the above operations in our pokemon Base All the work will be done in app py InsertionDeta provides ways of inserting data The first is through the put method put is the faster method of insertion If you call put on a record that already exists in the base put will overwrite the record In contrast insert is x slower than put In the case that you try to insert into the Base with an already existing key it will throw an error Let s create an endpoint to insert a new Pokemon with put Here is what the endpoint would look like using insert Deta also supports inserting multiple records at the same time with put many According to the documentation it is possible to insert at most items into the Base in a single call Deta Base SDK Let s test out what we have so far Let s insert the data for Pichu into the Base via an HTTP POST through pokemon on Postman Once you hit send navigate back to Deta Click on your Base under the Bases section You will now be able to view the data in your Base As you can see Pichu is in our pokemon Base AccessWe can use the get method to access the record of a given key Since our Pokemon name is the key we can directly access its record by providing its name We can test it with the following GET request UpdationAs stated previously in Insertion the put function can be used for overwriting records However put completely overwrites the record and can remove prior fields that are not part of the new updates As result if we want to partially update the record we can use the update function In fact update also allows for fine grained updations like incrementing values and appending prepending and removing elements in a list Deta Base SDK Let s make sure updating works with an example First I will insert the following data for Charizard region Johto Charizard is from Kanto region name Charizard height weight type Fire Charizard also Flying type evolution region should be Kanto and Charizard is also a flying type Let s update Charizard with a POST request to pokemon update Charizard After a GET request to pokemon Charizard it is clear that region and type are updated DeletionDeta provides delete a function that takes in a key and deletes the record associated with the key If I wanted to delete Charizard I would make an HTTP DELETE request to pokemon delete Charizard We have now explored how to insert access update and delete from our Base Let s learn how to query our Base QueryingPrior to querying make sure to fill up your Base with some more Pokemon Querying is done through the fetch method To elaborate fetch takes in a query or a list of queries and accumulates a list of records whose fields match the query or queries A query is nothing more than a dictionary where the mapping between the keys and values represents the query condition For instance suppose I wanted to get Blastoise s record with a query instead of get here is how it would work query name Blastoise results next db fetch query blastoise results We accumulate all the records with name equal to Blastoise It is also possible to query based on inequalities For instance we can query for all Pokemon that weigh greater than kg and are less than meter tall query weight gt height lt pokemon next db fetch query We can append “ gt and “ lt at the end of numerical fields to query for records with respective values greater than or less than a threshold There are a lot more suffixes that can be added to the end of a query field so I recommend reading the documentation for your specific use case Deta Base SDK Let s create an endpoint that will return Pokemon which are of a parameter type “ contains checks if a provided query element exists in the list associated with the field To provide an example if I wanted all the fire type Pokemon I would send a GET request to pokemon type Fire There are Pokemon returned from the above request This is a little overwhelming since this query will return all the fire type Pokemon in our Base Deta also provides us with the ability to limit the number of query results with buffer Let s set the buffer arg in fetch to Now we only get two records back Finally by changing the pages argument in fetch it is possible to spread the result data over multiple pages ConclusionMy primary goal with this writing was to shed greater light on a database that you can set up and work on in the blink of an eye It took hardly much time to create the project and based on the above examples CRUD and Querying are as simple as they can get For these reasons Deta Base is perfect for proof of concepts serverless applications hackathons and many more situations and projects that require simplicity and speed ResourcesDeta Home Flask Deta SDK Bulbapedia	2021-04-18 21:09:50
海外TECH	DEV Community	21 Popular JavaScript Libraries Every Web Developer Should Know	https://dev.to/ubahthebuilder/21-popular-javascript-libraries-every-web-developer-should-know-5746	Popular

to build simple websites CLIPBOARD JSAs its name already implies Clipboard allows you copy data from your site right off the bat No need to install any additional dependency BABELSome of us may be already be aware of the story of the tower of Babel in the bible Creating a language division amongst the builders to cut of communication and create discordance Well this tool is the solution to that problem in the context of JavaScript When creating code browser compatibility is open an issue to consider Older web browsers tend to be dropped in favour of newer ones but not all users update There are still machines and devices out there that are running old versions of web browsers Babel is a JavaScript compiler which compiles your JS code to ES compliant nature This means your code can run on new browsers such as Edge as well as older ones such as IE SVELTESvelte is a complete new approach to building user interfaces While traditional frameworks like React and Vue are browser based Svelte shifts that work into a compile step that happens when you build your app LETTERING JSLettering is an interesting JavaScript library for texts You can style and layout individual texts on your page

WebGL and uses HTML canvas if the former is not supported PixiJS is made of multiple consumable components that can be installed in your project with NPM YarnD JSD js is a JavaScript library for manipulating documents based on the nature of data received It stands for “Data Driven Documents which kind of explains its task The library uses pre built functions to select DOM elements create SVG objects style them and add transitions and other effects These objects can also be styled using pure CSS SOCKET IOYou should know that by default the connection between the browser and web server is closed once the server responds with data So how do you keep the connection open so data can seamlessly flow bi directionally without having to make new requests in the process Socket io based on web sockets is a JavaScript libabry which enables event based two way communication between the browser and the web server It utilizes a node js server MATH JAXAh good old maths As its name suggests
