Understanding Two-Way Binding in Angular 17
Tags: angular, angular17
Published: 2024-04-06 08:14:49

Angular, a powerful front-end framework, introduces a feature that seamlessly connects the Model (data) and the View (UI) — Two-Way Binding. This functionality ensures that changes in the View automatically propagate to the Model, and vice versa. Let’s delve into the intricacies of Two-Way Binding, exploring its syntax, applications, and how it combines both property and event binding.

## Two way binding

Two way binding is a feature in Angular that synchronizes the Model(data) and the View(UI). This means the changes in the View automatically updates the Model, and the changes in the View are reflected back to the Model.

Use two way binding to listen for events and update values simultaneously between the child and parent components

**Syntax**: It is denoted by the **[(ngModel)]** **(banana in the box syntax)** directive.

```
<!-- Two-way data binding example -->
<input [(ngModel)]="username">
```

The **[(ngModel)]** directive is a shorthand for binding the **value** property of the <input> element to the **username** property of the component and listening for input events to update the **username** property.

Two way binding combines both property and event binding

You can achieve two-way binding by using separate property binding and event binding. For example, with an input field:

```
<input [value]="username" (input)="username = $event.target.value">
```

This binds the **value** property of the input to the **username** property of the component, and the **(input)** event is used to update the **username** property when the input changes.

## Property binding

Helps you set values for properties of HTML elements and directives

```
<!-- Property binding example -->
<img [src]="imageUrl" alt="Image">
<button [disabled]="isButtonDisabled">Click me</button>
```

## One Way Binding(interpolation)

Interpolation is way to bind dynamic values directly into the text content of HTML elements.

```
<h1>{{ pageTitle }}</h1>

```
## Event binding

Allows you to respond to user events (such as clicks, keypresses, etc.) by triggering methods in the component.

```
<!-- Event binding example -->
<button (click)="onClick()">Click me</button>
<input (input)="onInputChange($event)">
```
The **$event** is a special variable that holds information about the event, such as the value of the input at the time of the event.

## Incase you did not know

· In HTML, an **attribute** is a value that is added to an HTML tag to provide additional information about the element. A **property**, on the other hand, is a value that is set on a JavaScript object to provide additional information about the object

· Directives are markers on the DOM element that tell Angular to do something to a DOM element or its children

"ERROR: Perform RPC timed out after 602.000s" in YSQL
Tags: yugabytedb, distributed, postgres, database
Published: 2024-04-06 07:13:46


When executing a SQL statement, the YugabyteDB query layer (known as YSQL and using PostgreSQL) sends read and write operations to the storage layer (DocDB). They are remote calls (RPC) and must time out if it takes too long, for whatever reasons. This is where you can experience such error: `ERROR:  Perform RPC (request call id 6171) to <ip_redacted>:9100 timed out after 602.000s`.

The parameters that control this timeout:
- client_read_write_timeout_ms cluster flag for YCQL and YSQL
- ysql_client_read_write_timeout_ms cluster flag for YSQL
- statement_timeout session parameter (PostgreSQL)
- hardcoded value of 600 seconds in YugabyteDB [code](https://github.com/yugabyte/yugabyte-db/blob/2.21.0/src/yb/client/session.cc#L409)

Here is the logic in [YBCSetTimeout()](https://github.com/yugabyte/yugabyte-db/blob/2.21.0/src/yb/yql/pggate/ybc_pggate.cc#L1623): There is a timeout set at YSQL level ([statement_timeout](https://postgresqlco.nf/doc/en/param/statement_timeout/)) and a timeout set at cluster level (`ysql_read_write_timeout_ms` ). When both are set, the timeout is set to the minimum of the YSQL and DocDB settings, which means increasing one above the other will allow longer waiting. 

If `statement_timeout` is set to zero, which is the default, it is considered not set, and only the DocDB setting matters.

Here are the defaults for DocDB parameters:
```
--client_read_write_timeout_ms=60000
--ysql_client_read_write_timeout_ms=-1
```

What is not visible from the parameters is when `ysql_client_read_write_timeout_ms` <0 it doesn't default to `client_read_write_timeout_ms` but to a hardcoded of 600 seconds (in [YsqlClientReadWriteTimeoutMs()](https://github.com/yugabyte/yugabyte-db/blob/2.21.0/src/yb/client/session.cc#L409))

This explains the error `timed out after 600.000s` in YSQL. If you want to allow longer queries to the storage, the solution is to increase `statement_timeout` to over 600000 (all those parameters are in milliseconds). If you want to reduce the timeout, the solution is to set `ysql_client_read_write_timeout_ms`

ReactX (RX)
Published: 2024-04-06 06:41:49

ReactiveX (Rx) is a library for composing asynchronous and event-based programs using observable sequences. It provides a powerful set of tools and operators for working with asynchronous data streams, allowing developers to easily manage and manipulate streams of data over time.

At its core, ReactiveX introduces the concept of Observables, which are sequences of data or events that can be observed over time. Observables can emit data, error, or completion events, and subscribers can react to these events asynchronously. This model enables developers to write reactive code that reacts to changes and events in a declarative and composable manner.

Rx offers a wide range of operators for transforming, combining, and filtering observable sequences. These operators allow developers to express complex asynchronous logic in a concise and readable manner. Additionally, ReactiveX libraries are available in multiple programming languages, including Java, JavaScript, C#, Python, and others, making it accessible to a broad developer audience.

ReactiveX is commonly used in applications where handling asynchronous operations such as network requests, user input, or UI events is a central concern. It is particularly popular in modern web and mobile development, as well as in reactive programming paradigms like functional reactive programming (FRP).

For example, In React.js, you can use ReactiveX (RxJS) for managing asynchronous operations, handling state changes, and dealing with event streams in a reactive and composable way. Here's a simple example demonstrating how you might use RxJS with React.js:

Let's say you have a component that fetches data from an API when a button is clicked, and you want to display the fetched data:
import React, { useState } from 'react';
import { fromEvent } from 'rxjs';
import { switchMap } from 'rxjs/operators';
import axios from 'axios';

const RxComponent = () => {
  const [data, setData] = useState(null);

  const fetchData = () => {
    // Simulate an API call
    return axios.get('https://jsonplaceholder.typicode.com/posts/1');
  };

  const buttonClickStream = fromEvent(document.getElementById('fetchButton'), 'click');

  buttonClickStream
    .pipe(
      switchMap(() => fetchData())
    )
    .subscribe(response => {
      setData(response.data);
    }, error => {
      console.error('Error fetching data:', error);
    });

  return (
    <div>
      <button id="fetchButton">Fetch Data</button>
      {data && (
        <div>
          <h2>Data:</h2>
          <p>{data.title}</p>
          <p>{data.body}</p>
        </div>
      )}
    </div>
  );
};

export default RxComponent;
I made a stop watch with html

## stopwatch
I always wanted to make an easy app that has a clock ,a stopwatch and a weather forecast card out of which I completed working on one feature which is the clock. The second feature which I did is the stopwatch which contains little more html than the last and JavaScript . It literally has 70lines of JavaScript and CSS if we want to do so .This app took me literally 2days to do while the clock on the other hand 1day .So I literally got mad of that JS as I used to do so .
