海外TECH	DEV Community	Easy Smart Contract Debugging with Truffle's Console.log	https://dev.to/mbogan/easy-smart-contract-debugging-with-truffles-consolelog-3l1b	Easy Smart Contract Debugging with Truffle x s Console logIf you re a Solidity developer you ll be excited to hear that Truffle now supports console logging in Solidity smart contracts While Truffle has long been a leader in smart contract development toolingーproviding an easy to use environment for creating testing and debugging smart contractsーa directly integrated console log was a feature it still needed But no more Developers can now easily log messages and debug their smart contracts all within the familiar Truffle Ganache environment Let s look at how What Is Console log Console log is a very popular feature in JavaScript and is widely used by developers to easily output logging messages and extract details directly from code In the context of web and smart contract development console log plays a similar role allowing developers to print out Solidity variables and other information from their smart contracts For example you can use console log to display the value of a variable or the output of a function call within your smart contract This can be extremely useful when debugging or testing your smart contract console log Console Logging The Smart Contract Developer s Best Friend How To Use Console Logging in TruffleMaking use of console log is quite straightforward First you ll have to ensure you have an up to date Truffle version running on your computer If you have any issues you might want to uninstall the package entirely then reinstall it For the commands used in this post we ll use NPM as our package manager npm install g truffleAfter a successful installation I suggest that you modify the truffle configuration file i e truffle config js as follows module exports solidityLog displayPrefix defaults to preventConsoleLogMigration true defaults to false displayPrefix decorates the outputs from console log to differentiate it from other contents displayed by the CLI preventConsoleLogMigration screens contract deployments from going through when on a test or mainnet You can opt out of this if you wish to deploy your contract with the console log included However if you choose to do this keep in mind that console log has unpredictable behavior when it comes to gas usage Now you re ready to try it out Import the contract sol contract into your Solidity code as usual Now you re ready to use the console log command as you would in JavaScript This includes using string substitutions like s and f pragma solidity import truffle console sol contract BookStore function transfer address to uint amount external console log Transferring s tokens to s amount to require balances msg sender gt amount Not enough tokens balances msg sender amount balances to amount emit Transfer amount to msg sender The above transfer function shows console log in action Imagine a call to the transfer function failing with the “Not enough tokens error The console log line in this case will show the number of tokens the call is trying to transfer This allows the developer to see the address and amount of tokens being transferred The message will look like this Transferring tokens to xbbcaebaeebedceccAn even better way to debug this could be to add in the balances msg sender into the console log statement or print it out on a separate line That way the sender s balance is visible in the console too You get the point You can also leave logs in test and mainnets this way you ll have a nice way to observe your smart contract And it s worth mentioning that tools like Tenderly will integrate the scrapping of logs which can be useful when debugging and testing smart contracts in a production environment Finally when using console logging it s important to follow all the good usage rules you already know such as using clear and descriptive log messages This will make it easier to understand the output and identify any issues that may arise Other Debugging Tools in TruffleWhile console logging is a powerful tool for debugging smart contracts keep in mind that Truffle offers other debugging tools as well Truffle has a powerful built in debugger CLI tool that can be used to step through the execution of a smart contract and inspect the state of variables at different points in the execution Additionally events are a nice way to log messages and track the behavior of a smart contract That said it s worth noting that using the debugger for something as simple as variable output can be overkill Similarly event logging only works when the transaction succeeds which can be a limitation in certain situations The bottom line is that the console log featureーin combination with the other debugging tools in Truffleーcan provide a better developer experience thanks to its simplicity and ease of use It gives developers the ability to quickly and easily log messages and monitor the behavior of their smart contracts while the other debugging tools can be used for more advanced debugging and troubleshooting Try It OutTruffle s new console logging feature is a valuable addition to smart contract development It s easy to use and can streamline the debugging and testing process The ability to log messages and track the behavior of smart contracts in real time can reduce inefficiencies and headaches It s a great tool to have in your toolbox	2023-01-26 13:53:11
海外TECH	DEV Community	Please, give me a feedback	https://dev.to/josethz00/please-give-me-a-feedback-457	Please give me a feedbackWhen you are doing something you probably want to know if you are doing it correctly and if not how you could improve Humans are social and smart animals so we tend to seek validation of our actions but be careful Validation ≠FeedbackFeedback is a form of obtaining validation but not only it it is also about revalidating old ideas exchange knowledge expose strengthnesses and weaknesses and summarizing all of these things to be a better person professional How frequently you receive feedbacks How frequently you give feedbacks It is very important to give feedbacks as is to receive them   Why are feebacks important Is it safe to drive a car that hasn t been serviced by a mechanic in years NoBut is it possible YesHow high are the risks Very high the car may end up breaking down in a critical momentThe same thing applies to people you can maintain an employee for years without giving him a single feedback However for not giving regular feedbacks you certainly have no idea of what s going on in his head Maybe your employee is thinking about quitting the job maybe he is wanting a promotion maybe he is overwhelmed maybe he is tired You will never know until you start doing regular feedback sessions with your team   Feedback sessionsFeedbacks must be bilateral it means that everyone involved in the feedback session should have the right to speak but also the duty to listen The most common type of feedback session is the famous alignment As a manager mentor you must be prepared to speak whatever is necessary but also to hear you may have to answer some questions   How it feels to be ignored Someone already ignored you I guess so and you probably didn t feel good when that happened Some people feel ignored at work when they do not receive feedbacks from their superiors These people will start to think that nobody cares about their work so they will be demotivated and will start start commiting more and more mistakes   How to solve this Start giving feedbacks obviously As soon as possible But remember feedbacks build trust and are also based on trust so if you spent many months without giving a single feedback to the people who work with you ONE feedback won t solve your problemas You are gonna have to be constant regular feedbacks to recover the lost time and to build trust   Don t let the cycle begin againOnce your team members are motivated again don t stop giving them feedbacks break the cycle Continue with the regular feedback sessions keep iterating   AutonomyMicromanagement is bad you have to give feedbacks at the same time that you release your team to be more independent Let you coworkers do more tasks is a clear and good sign of trust you are delegating the tasks because you believe they are capable to make it   People are differentSome people need more feedback than others some people can survive more time without receiving feedback others will require feedback every time As a manager you have to know and accept this People that require more feedback may be insecure or anxious and people who avoid feedbacks may be shy and are trying to avoid potential awkward situations   Don t skip the corrective feedbacksGiving and receiving positive feedbacks is way easier than corrective feedbacks Corrective feedbacks are meant to modify a behavior that isn t good so they usually happen when something is going wrong As a manager you need to tell your employees when something isn t good and as a employe you have to calmly listen to what your manager is saying and then try to absorve everything that you think that s useful to improve your performance Corrective feedbacks should not be offensiveWhen giving a corrective feedback be careful to don t disrespect your coworker with too harsh words shouting and other offensive communication behaviors	2023-01-26 13:34:54

海外TECH	DEV Community	Frameworks: Choosing between React, Angular and Vue.	https://dev.to/oluwatrillions/frameworks-choosing-between-react-angular-and-vue-48f3	Frameworks Choosing between React Angular and Vue Frameworks have helped make JavaScript load time faster Using pure JavaScript for large projects that update from time to time is suicidal and hence the need for frameworks What are JavaScript frameworks These are collections of JavaScript code libraries that provide developers with pre written JavaScript code so these libraries can be used in projects A framework takes absolute control of the structure of the project its features and its behavior Think of a framework as a car with multiple libraries such as steering oil gauge carburetor engine etc The car controls how these other parts work and when they work A framework cannot work on its own without the collection of libraries built into it the same way a car can t function on its own without the engine Yes that s a framework I can say for sure that over of JavaScript frontend developers use one framework or another because it makes work faster and also makes JavaScript easier to use Using vanilla JS can be a suicide mission because of its complexities when used for large projects or when you need a faster application So now let s talk about which framework you should choose after getting familiar enough with JavaScript Our frameworks to choose from are React Angular and Vue and that s because these are the most preferred and popular front end frameworks used by developers in the space REACT JS This is the most popular and most widely used framework out there by front end developers in developers use React for their projects and this is because it is fast reusable scalable and has a very large community supporting React has so many advantages that will make you adopt it as your preferred framework Let s look at some of the reasons why so many developers use React It is component based Components are self contained modules of code that make it easier to manage state and reuse code Since most of the codes we write as front end developers is to solve state management components make it easier to separate state and not just lump all the UI in one file With components codes are easier to write read re used and modified It uses the virtual DOM This is one of the reasons why React is the fastest framework Because it uses the virtual DOM React only re loads the part of the UI where changes were made Unlike vanilla JS that reloads the whole entirety of the page only the component that changed is reloaded thereby resulting in a faster application It supports enterprise applications React has made enterprise applications endearing because of its so many advantages and ease to use Enterprise codes are written in separate bits for easy read and management and React has that offered that on a platter of gold such that enterprises only have to manage code in one component instead of having to make changes in a very large codebase React also has some Flaws and notable among them is the fact that it only supports the View in the Model View Controller MVC pattern ANGULAR JS This is a structural framework for perfect Single Page Applications SPAs It was the first of it s kind because it set the tone for the invention of other front end frameworks Angular is easy to learn and use and one of it s biggest advantages over other frameworks is that it can be used directly in HTML using the tag as entry Like React Angular has some reasons why the earlier adopters of frameworks adopted it and why some new developers prefer it too Let s see some of those reasons Applications built with Angular have very good performance if not the best Angular has good maintainability It supports the Model View Controller MVC pattern The MVC pattern divides your codes into three segments model view and controller Model represents data View represents UI and Controller represents the logic This pattern makes codes esier to read and maintain The notable Flaw in Angular is that it uses the regular DOM which loads the entirety of the page when changes are made to the code and so this makes loading time slower VUE JS Vue is an adaptable framework in that it can be easily integrated with other frameworks Vue is a perfect framework for the undecided developer torn in between Angular and React because Vue allows you to write your UI template in HTML like Angular and package these templates into components like React Vue supports both HTML and JSX so it is easy to learn and use Reasons why some developers prefer it is limitless and it s the fastest growing framework so far Let s highlight some of the reasons It is very easy to learn and use It is very adaptable and can easily be integrated into other frameworks It can be used for large applications It s the best of both worlds in Angular and React MY VERDICT I ll choose React because it is widely adoptable and is simply the most used by enterprises and the most sought after framework by RECRUITERS If you think this was helpful you can Follow me and like the article It will encourage me to write more articles
