海外TECH	DEV Community	How to avoid AWS unintentional charges ?	https://dev.to/aws-builders/how-to-avoid-aws-unintentional-charges--3dam	How to avoid AWS unintentional charges Hello Devs Hope everyone is doing well This blog will be similar to my other blogs where I came across one problem and I struggled to solve then finally able to solve As the title suggests in this blog I am going to talk about how to avoid AWS charges which we do sometimes unintentionally like without checking in details settings and we just do click click and set up a particular service Actually a few days back I was helping one of my friends to set up his AWS cloud infrastructure for a website I was setting up EC ELB Route RDS in AWS As EC was basic one selected and ELB was selected as classic load balancer per Classic Load Balancer hour or partial hour per GB of data processed by a Classic Load Balancer But RDS was not selected as a basic requirement to handle big data import processing What did I did while creating RDS Selected AWS console gt RDS Asia Mumbai region Standard create gt MySQL Template I choose as Production Use defaults for high availability and fast consistent performance Standard instance name username and password setting Selected db t medium vCPUs GB RAM No EBS optimised Selected Provisioned IOPS SSD io Kept as value to provisioned IOPS Also kept checked Enable storage auto scaling option Created Multi AZ instance Others rest of setting normal as it like Security group VPC Authentication Note Provisioned IOPS SSD io and io volumes are designed to meet the needs of I O intensive workloads particularly database workloads that are sensitive to storage performance and consistency What mistake made in above steps Step number and was a mistake which I ignored and forgot to understand the pricing model Step is the bigger culprit for causing unintentional charges Actually the website was not running that big scaling level to use those params See my billing for reference What help to reduce pricing Selecting General Purpose SSD gp Unchecked Multi AZ environment This step is recommended when going to actual production and big scale level Not the initial stage Disabled Enabled storage auto scaling option This helps me to reduce pricing from to range What action I will recommend to avoid unintentional charges Above RDS example is one of the services which charge a higher one But make sure while creating other services give more importance to all default option before clicking on final create button Choose option or scaling or instance type which you required based on environment and scaling expectation Why to pay extra if scaling is not accepted on production environment Last action is important One is to use the AWS Pricing Calculator tool to evaluate a better pricing model Use this tool before creating any AWS service I made a big mistake ignoring this What is the AWS Pricing Calculator AWS Pricing Calculator is a tool which provides you the option to select service and configure options based on requirement like instance type SSD IOPS bandwidth request count Mark my word it gives exact similar pricing which you will be billed on usage Experiencing same thing now Choose exact params and calculate pricing It is free of cost to use It gives you the option to export as PDF or Excel How does it works Benefits Transparent pricingShare your estimatesHierarchical estimatesEstimate exports Best use cases Reduce spend on EC Reduce spend on RDS usage Estimate your AWS usage for approval This is about my experience on how I landed to pay higher charges and avoid unintentional charges for later use Thanks to the AWS Community Builder group who help and guide me here to solve this issue Proud to be part of this group Hope it will solve your issue if you come across a similar problem Feel free to comment if you have any issues If you like my blog please don t forget to like the article It will encourage me to write more helpful articles You can reach out to me over my twitter handle aviboy References	2022-05-01 17:28:31

海外TECH	DEV Community	Set up ESLint, Prettier and Husky in a React project | a step by step guide	https://dev.to/yvad60/setup-eslint-prettier-and-husky-in-a-node-project-a-step-by-step-guide-946	Set up ESLint Prettier and Husky in a React project a step by step guideWhen setting up a new project especially the one that will be worked on by many people team code quality is an important aspect to put into consideration and make your codebase more clean and standardized in this tutorial I will walk you step by step into setting up Eslint Prettier and Husky and getting them ready to work in your next project For this example we will be setting up those tools as a React Project and we will be using Eslint with Airbnb PrerequisitesNode we will be working in the node environment therefore you will need to have it installed on your machine VSCode as our code editor that s all you need let s get started Understanding these toolsthe main point of these tools is to ensure the quality of your code when working alone or working as a teamEslint is a linter for JavaScript linters are tools that will help you set up rules to follow as you write your code and they ensure that you follow your rules Prettier Is a code formatter that automatically formats your code to look cleaner and easier to read there are several code formatter but prettier is the most popular oneHusky is a tool that allows us to run scripts especially while using version control like git for our example we will be using husky to set up pre commit scripts to run prettier and Eslint on every commit You need to be working in a git repository to be able to use Huskywe will get back to these tools later in the guide for now follow the following steps Installing Eslint dependenciesEslint is a lint for identifying and reporting on patterns found in ECMAScript JavaScript code lints or linters are tools that are used to flag programming errors bugs stylistic errors and suspicious constructs to reduce errors and improve the overall quality of your code in some cases they can spot those errors and auto fix them for you Eslint specifically is a popular open source lint that works best with JavaScript and TypeScript it allows us to configure and customize it to our needs by specifying your own rules or extending standardized rules from companies like Google Airbnb Run the following command to install ESLint as a dev dependency npm install eslint save dev Configuring ESLintin this guide we will be configuring ESLint with Airbnb JavaScript styles which are standard when it comes to JavaScript This means that Eslint will check our code according to what s allowed and not allowed by the Airbnb style guide you can learn more about the Airbnb JavaScript style guide herefollow this step to configure Eslintnpm init eslint configyou will need to answer some questions about how you would like to use eslint follow the following configuration note that I chose react as the library Airbnb as the style guide and JSON as the file format You can change these configurations according to your project after following the above steps a file named eslintrc json should be created with the following code will be auto generated according to the configuration made above that object of rules is where you can put your own rules if you want to but for now we are using Airbnb rules as mentioned in extends plugin react recommended airbnb For more on eslint rules you can check their official site here Installing Prettier dependenciesprettier is an opinionated code formatter that styles code consistently and is easier to use it supports HTML CSS Javascript and most of their librariesrun this command to install prettier as a dev dependency note that save exact ensures that everyone will install the same version of prettier to avoid inconsistencynpm install save dev save exact prettier Configure Prettierin the root folder create a file named prettierrc json this will contain custom rules options that you may want prettier to follow while formatting your code enter the following code in your prettierrc json tabWidth useTabs true printWidth semi true trailingComma es singleQuote true endOfLine lf you can learn more about these prettier rules and more here Integrating Prettier with ESLintAs mentioned above we will be using Eslint as our linter and prettier as our code formatter Linters usually contain not only code quality rules but also stylistic rules Most stylistic rules are unnecessary when using Prettier but worse they might conflict with Prettier so to use them both safely we had to install eslint config prettier dependencyrun the following commandnpm install save dev eslint config prettiereslint config prettier Turns off all eslint rules that are unnecessary or might conflict with Prettier to make sure that eslint only check code syntax style while Prettier check code formattingto configure eslint config prettier in your eslintrc json extent prettier add it as last like following env browser true es true extends plugin react recommended airbnb prettier parserOptions ecmaFeatures jsx true ecmaVersion latest sourceType module plugins react rules Configure scriptsto be able to run ESLint and Prettier we need to add scripts in our package json as the following scripts lint eslint fix max warnings format prettier write lint eslint fix max warnings this script runs eslint from the root folder and auto fix error and checks that we don t have any warning format prettier write this script will run prettier from the root folder and auto fix format errors Installing HuskyHusky is a tool that allows us to work with Git hooks Git hooks are scripts that you can set up to run at certain events in the Git lifecycle like before every commit or push In our case we will be using Husky to run ESlint and Prettier as our pre commit hook so that no one will be able to commit when their code doesn t follow our rules creating pre commit and configuring Husky can be challenging to set up and share across the team therefore we will be using a tool called lint staged that installs Husky and set up everything for you and you only specify scripts to run on every commit the best part is that with lint staged we save time by only checking staged changed files since we don t want to check in every file if we didn t edit themMake sure your folder is a git directory run the following command to install lint stagednpx mrm lint stageda folder called husky will be created including different files as mentioned belowthe command npx lint staged in the pre commit file means that on every commit git will run scripts in the lint staged command in package jsonif you open package json you will notice that lint staged entry was added at the bottom like the following lint staged js eslint fix js css md prettier cache write by calling npx lint staged these commands in this lint staged object will be triggered and for all js we would run eslint and on all js css md you can even add html json if you have any we would run prettier we can even run the scripts that we configured earlier like the following lint staged js npm run lint js css md html npm run format Bonusfor better experience if you are using VSCode you can install ESLint and Prettier extension that will work better with the above configuration There you have it you just configured Eslint prettier and Husky in a node project next time you have a team or an open source project your code quality will be ensured I will see you in a next one	2022-05-01 17:02:44
