Ontem saiu o Node.js v18.15 com uma pancada de coisas legais e esse bug eu havia corrigido no 19 e finalmente ele veio para a versão LTS
Pra mim, essa é a prova de que quantidade de código não tem nada a ver com produção ou impacto

As Node.js Streams são parte do Node.js desde o início e muita coisa interna do Node.js as usa para controlar eventos e processar dados sob demanda

Generator function* in JavaScript:
A thread 🧵
#100DaysOfCode #javascript #Angular #reactjs #devbubble
A thread 🧵
#100DaysOfCode #javascript #Angular #reactjs #devbubble
In JavaScript, generator functions are a special type of function that allows you to use the yield keyword to pause and resume the execution of the function.
#100DaysOfCode #NodeJS #CodeLife
#100DaysOfCode #NodeJS #CodeLife
They allow you to create iterators, which are objects that can be used to iterate over a sequence of values.
A generator function is defined using the function* keyword and can be invoked using the yield keyword.

Memoization is a technique used to optimize the performance of a function by caching its results for a given set of inputs.
#100DaysOfCode #reactjs #Angular #NodeJS
#100DaysOfCode #reactjs #Angular #NodeJS
The idea is that if a function is called multiple times with the same input, it's more efficient to return the cached result instead of re-computing the result each time.

Data virtualization: With Proxies in JavaScript.
A thread 🧵
#100DaysOfCode #javascript #rarely_used #devbubble
A thread 🧵
#100DaysOfCode #javascript #rarely_used #devbubble
Data virtualization using Proxies in JavaScript refers to the ability to create virtualized data structures, such as virtualized arrays, that load their data on demand rather than loading all data at once.
#100DaysOfCode #ReactJS #Angular
#100DaysOfCode #ReactJS #Angular
This can be useful for improving the performance of an application when working with large data sets.
In this Eg., we create a VirtualArray class that takes in two args- the length of the array & a loader function.

Estava produzindo uma super aula do meu curso de Node.js Streams (em inglês), ensinando sobre como paralelizar o processamento de arquivos usando Node.js
A ideia é subir um processo para cada arquivo, e cada processo filtra os usuários que possuem o email em dominio gmail

Só que eu automatizei a validação para verificar que todos os itens foram processados e enviados para um arquivo de saida
Então primeiro fui lá e usei o `grep` para filtrar o texto do arquivo e o `wc -l`, para obter a quantidade de linhas.

A WeakMap is a map that holds weak references to its keys.
This means that the keys are eligible for garbage collection if there are no other references to them.
This feature can be useful for implementing caches or other similar data structures.

#reactjs #Angular #NodeJS #js
A WeakMap is a special kind of map where keys must be objects and the map doesn't prevent garbage collection of its keys.
You can think of a WeakMap as a map that doesn't "own" its keys, and therefore doesn't keep them alive.

Announcing that a core part of @logseq is now scriptable with #NodeJS through github.com/logseq/nbb-log…! This means you can query and analyze your graphs with independent applications. Two specific use cases that are now possible:
Node.js scripts can run any #Datalog query that the Logseq app can. These scripts run independent of a Logseq app and can run in CI environments like Github actions. Learn more at github.com/logseq/nbb-log…
Node.js scripts can extract almost every actionable piece of text Logseq recognizes e.g. a url, property, page reference, etc. Learn more at github.com/logseq/nbb-log…

How to create a simple Express server in Nodejs 👇
First, you will need to create a project folder and then install the Express library.
To do this, open a terminal window and type:
npm install express --save
To do this, open a terminal window and type:
npm install express --save
Once installed, create a file called index.js in your project folder.
This is where you'll write the code for your server.
In the index.js file, add the following code to import the Express library and start the server:

Node.js is based on the V8 JavaScript engine developed by Google, which means it compiles and executes JavaScript code at high speed. This makes it an ideal choice for building real-time, data-intensive applications.

One of the key advantages of using Node.js is its event-driven, non-blocking I/O model. This means that it can handle a large number of concurrent connections with minimal overhead, making it perfect for applications that require high scalability.

How to consume any Database as a Stream for heavy data processing using JavaScript 🤯🔥

The secret for processing anything using JavaScript is to handle data on demand.
Imagine data you wanna migrate data from a SQL database to a NoSQL DB. You would need to apply some business rules, clean up fields, filter data and then output them to the final output.

You might know that you can block the Node.js (and the data source you're consuming) if you handle too much data at once in memory
The best practice then is to limit results, send individual data to a stream pipeline, and then ask for more data until you've consumed it all.
