How we shrunk our Javascript monorepo git size by 94% This isn't click bait. We really did this! We work in a very large Javascript monorepo at Microsoft we colloquially call 1JS. It's large not only in terms of GB, but also in terms of sheer volume of code and contributions. We recently crossed the 1,000 monthly active users mark, about 2,500 packages, and ~20million lines of code! The most recent clone I did of the repo clocked in at an astonishing 178GB. #JavaScript #MonorepoOptimization #GitPerformance #CodeOptimization #SoftwareEngineering #DevOps #MicrosoftEngineering #CodeEfficiency #RepositoryManagement #ScalableCodebases https://lnkd.in/g9RPZbku

After reviewed a lot of open-source code, and corporate repositories, found one common typescript mistake that developers usually make. I was also the same person who made this mistake, but due to some unintended behavior, I dug deep and improved my practice. Many developers use typescript deceleration files (“.d.ts”) in a way that is not recommended. The Typescript team strongly discourages this practice. So, what the mistake actually is: 👎 Developers often use “.d.ts” files instead of .ts files for declaring types. 👎 It is surprising that many developers use .d.ts files for defining the types of regular modules. 👎 On the surface, .d.ts files may seem to behave the same as normal modules, but they have different purposes. Issues with the “.d.ts” file: ❌ TypeScript's type checking skips .d.ts files by default. ❌ .d.ts files are meant only for types, not runtime code. ❌ Adding runtime features to .d.ts files leads to errors. “.d.ts” files should not contain runtime code. ❌ Declarations in .d.ts files become available globally, causing naming conflicts and dependency management challenges. Purpose of Declaration Files: ✅ Declaration files are used by TypeScript to understand and type JavaScript files. ✅ They are used alongside JavaScript files to describe the types of the code. ✅ Placing .d.ts files alongside JavaScript files allows TypeScript to understand and provide accurate typings for JavaScript libraries. Recommendations: 👍  Using .ts files for types is recommended. 👍  Types should be put in normal modules like any other code, not in .d.ts files. 👍  .d.ts files should only be used for global alterations to interfaces and making changes to the global scope. Typescript also does not recommend this practice: https://lnkd.in/dCW_kDV5 if you find this post helpful for you, feel free to like, follow, and repost, and share the coding motivation to others. #typescript #javacript #practices #bestpractices #tips #tricks #scope #js #react #reactjs #next #nextjs #ts #eslint #opensource #developers #engineers #software #frontend #backend #code #dailytips #coding

Why is typescript so popular with enterprise solutions? Well with a few estimations we can see why it makes sense. 1. My team had about 4 people actively working on the front end Javascript code. 2. I had at most 3 tickets come to me about types in the 4 years I was on the team. 3. When a bug did come in, the fix was obvious and took about 15 minutes in total. How many customers were affected by a “type” bug? 1. 10M visitors/day 2. Estimate 0.25% saw the bug  3. About 30 days for the bug to be identified, put in a sprint and get the fix in production 10M * .0025 * 30 days * 3 tickets * 4 people / 4 years = 2.25M users affected per year. or DailyVisitors * .225 = totalAffected per year What are the costs of Typescript? Typescript runs at about a 1:1 compared to Javascript... so nothing there. One time costs: 1. Upfront training (1-2 days) 2. Converting code base to typescript (One person 2 weeks using a codemod?) Is a one time 3-4 week investment worth a more positive user experience for 2.25M users every year? That sounds like a pretty good tradeoff to me. I think it makes more sense if you’re using node.js as your backend, because then a type issue causes more than just a page refresh, or if you have substantially more daily visitors. Some people will get hung up on details of the estimation, but this exercise is really meant as a rough approximation to determine if it’s a reasonable decision.

🚀 NestJS is a great framework for building NodeJS APIs. While doing so, one major issue is the validation of input/output data. ⚠️ The NestJS team recommends using `class-validator`, but there is a better way. ✨ Using `openapi-express-validator` solves a few issues of the first approach: 📄 Greatly improves maintainability 📚 Ensures API documentation consistency 🔄 Reduces code duplication 🤔 Which request/response validation technique do you prefer? 👏= `class-validator` 💡= `openapi-express-validator` 😆= validation?!? who cares?

🚀 New article about injecting environmentvariables in statically built web applications with Vite and Nginx In this article, I explore methods for injecting environment variables into statically built web applications using Vite and Nginx. You'll learn how to automate this process using a Docker container and the envsubst tool to replace variables at runtime. Each step from project creation to container deployment is thoroughly explained and illustrated with code examples. I've also included a link to the repository with the complete source code.
