### Configurando Seu Projeto React com Vite


Olá novamente, desenvolvedores! Se você ainda não conferiu a Parte 1 deste guia, onde instalamos as ferramentas necessárias, não hesite em [clicar aqui] para começar do zero. Agora que estamos prontos, vamos prosseguir com a criação do nosso projeto React usando Vite.

**1. Iniciando um Novo Projeto Vite**

Primeiro, abra o seu Visual Studio Code (VSCode) e acesse o terminal. Eu geralmente utilizo o Git Bash, mas você pode escolher o terminal que preferir. No terminal, execute o seguinte comando:

```
npm create vite@latest
```
Este comando irá iniciar o processo de criação de um novo projeto Vite. Ele solicitará que você insira o nome do seu projeto. Você pode chamá-lo do que quiser, vou chamar o meu de “portfoliov2”, pois esta é a segunda iteração do meu portfólio. Após inserir o nome, você será solicitado a escolher algumas opções, como a linguagem e o gerenciador de pacotes.

Coloque o nome que quiser!

**2. Configurando as Opções do Projeto**

Escolha as seguintes opções:

**- Template**: Selecione “React” para criar um projeto React.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fzk5g3ukg7a7kcso1bxl.png)

Vamos usar React para o projeto.

**- JavaScript/TypeScript**: Escolha “TypeScript” para tirar o máximo proveito da tipagem estática que o TypeScript oferece.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/aolthakb9id1x76ej4j9.png)

Escolha TypeScript

Agora que você fez essas seleções, o Vite irá criar a estrutura inicial do seu projeto React em uma pasta com o nome que você escolheu (“portfoliov2”, no meu caso).

**3. Navegando até a Pasta do Projeto**

Para entrar na pasta do seu projeto, use o comando cd (change directory, directory é basicamente “pasta”) seguido pelo nome do projeto. No meu caso, eu usaria o seguinte comando:

```
cd portfoliov2
```
Isso fará com que você entre no diretório recém-criado, onde todo o código-fonte do seu projeto React está localizado.

**4. Instalando as Dependências**

Agora que você está dentro da pasta do projeto, é hora de instalar todas as dependências necessárias. Para fazer isso, execute o seguinte comando:

```
yarn
```
Isso instruirá o Yarn a instalar todas as bibliotecas e pacotes necessários para o seu projeto React. Aguarde até que o processo seja concluído.

Pronto! Agora você tem um projeto React configurado e pronto para ser desenvolvido. Na próxima parte deste guia, exploraremos como iniciar o servidor de desenvolvimento, fazer alterações e ver seu aplicativo React ganhar vida.

Continue acompanhando este tutorial sobre como iniciar um projeto React com Vite. Estamos apenas começando, e as próximas etapas serão ainda mais empolgantes!

PostgreSQL's MVCC: Navigating Concurrent Data Access
Tags: postgressql, apacheage, database, mvcc
Published: 2023-08-31 16:51:45

PostgreSQL shines with its Multiversion Concurrency Control (MVCC) model. This approach empowers developers to ensure data consistency and boost performance in multiuser environments.

## Snapshot Consistency

- MVCC lets SQL statements operate on data snapshots, preventing inconsistent views caused by concurrent transactions.

## Lock-Free Efficiency

- Traditional locks for reading and writing data don't conflict in MVCC.
- Reading never blocks writing, and writing never blocks reading.

## Serializable Snapshot Isolation (SSI)

- PostgreSQL takes MVCC further with SSI.
- Guarantees strict transaction isolation without performance trade-offs.

## Explicit Control

- Table- and row-level locking options are available.
- Useful for manual conflict management, though MVCC usually offers better performance.

## Flexible Advisory Locks
- PostgreSQL introduces advisory locks for broader use cases.
- Offers adaptable locks beyond transaction boundaries.

## Concurrency Optimization
- MVCC empowers developers for effective concurrent data handling.
- Balances data consistency and performance for seamless multiuser interactions.

## Conclusion
PostgreSQL's MVCC is a pivotal tool for efficient concurrent data access. By embracing snapshots, avoiding lock conflicts, and leveraging advanced features like SSI, developers can create high-performance applications while upholding data integrity. Whether optimizing concurrency or building multiuser systems, PostgreSQL's MVCC is a valuable asset.

WAL buffer and WAL segment file
Tags: postgres, apacheage
Published: 2023-08-31 16:50:03

WAL stands for Write-Ahead Logging. It is a standard method for ensuring data integrity. WAL data is a description of changes made to the actual data, and is also known as metadata.

WAL’s central concept is that changes to data files (where tables and indexes reside) must be written only after those changes have been logged, that is, after log records describing the changes have been flushed to persistent storage. This ensures that in the event of any error, we will be able to recover the database using the log. Any changes that have not been applied to the data pages can be redone from the log records. This is roll-forward recovery, also known as REDO.
WAL buffers and WAL segment files are two components of the WAL system in PostgreSQL.

**WAL buffers** are in-memory buffers that temporarily hold transactions until they are written to disk. They are used to speed up write operations by allowing transactions to be written to disk in batches rather than one at a time. If the WAL buffer becomes full, the contents of the buffer are dumped into a WAL segment file.

**WAL segment files** are on-disk files that store the contents of the WAL buffer when it becomes full. They are used to ensure that all transactions are written to disk before being acknowledged as complete. When a new transaction is started, it is written to a new WAL segment file.
How does no code app development work?
Tags: webdev, nocode
Published: 2023-08-31 16:43:06

[No-code app development](https://thenocodexperts.com/) is a revolutionary approach that allows individuals with little to no programming knowledge to create mobile or web applications without writing a single line of code. Instead of traditional coding, no-code platforms use visual interfaces and drag-and-drop tools to design, build, and deploy applications.

**The process typically involves the following steps:
**
1 **Platform Selection:** Choose a suitable no-code app development platform that aligns with your project requirements and goals.
Design and Layout: Utilize the platform's visual interface to design the layout and user interface of your application. Drag and drop elements such as buttons, images, and text boxes to create the desired design.

2. **Data Modeling:** Define the data structure and relationships within your application. No-code platforms often provide pre-built databases and data models that can be customized to suit your needs.

3. **Functionality Integration:** Use the platform's built-in functionalities and pre-built components to add desired features to your app, such as user authentication, data storage, and notifications.

4. **Testing and Iteration:** Once the app is built, thoroughly test its functionality and user experience. Iterate and make adjustments as needed to enhance performance and usability.

5.**Deployment:** Publish your app to the desired platform, whether it's an app store for mobile apps or a web server for web applications.

No-code app development democratizes the app creation process, empowering individuals and businesses to bring their ideas to life quickly and efficiently, without the need for extensive coding expertise. 

It's an excellent option for those who want to create simple applications or prototypes without the complexities of traditional coding languages. However, for more complex and customized applications, traditional coding may still be necessary.
PostgreSQL Triggers: Simplifying Automated Actions
Tags: apacheage, postgressql, database, triggers
Published: 2023-08-31 16:41:09

PostgreSQL triggers offer a powerful mechanism for automating actions within the database.

## Trigger Basics

- Triggers execute specific functions automatically upon defined operations.
- They can be attached to tables, views, and foreign tables.
- Triggers can fire before, after, or instead of INSERT, UPDATE, DELETE, and TRUNCATE operations.

## Varieties of Triggers

1. Row-Level Triggers: Executed once per modified row.
2. Statement-Level Triggers: Executed once per SQL statement.
3. INSTEAD OF Triggers: Used on views to modify underlying tables.
4. BEFORE Triggers: Fired before the operation.
5. AFTER Triggers: Fired after the operation.
6. INSTEAD OF Triggers: Fired instead of operation (views only).

## Trigger Execution Sequence

- Triggers are invoked in alphabetical order by trigger name.
- If a BEFORE trigger returns NULL, subsequent triggers are not fired for that row.
- Statement-level triggers are executed even if no rows are affected.

## Trigger Functions and Cascading

- A trigger function is defined before creating the trigger.
- Trigger functions are invoked within the same transaction as the statement.
- Be cautious of cascading triggers that might lead to recursion.

## Examining Trigger Data

- Trigger input data includes the type of event (e.g., INSERT, UPDATE) and arguments.
- Row-level triggers have access to NEW (INSERT/UPDATE) and OLD (UPDATE/DELETE) rows.
- Statement-level triggers can request transition tables to access affected rows.

## Practical Uses of Triggers

- Validation: Enforce data consistency with checks before modification.
- Auditing: Log changes for auditing purposes using AFTER triggers.
- Synchronization: Propagate updates to related tables.
- Default Values: Automatically insert default values.
- Data Transformation: Modify data based on specific criteria.
- View Modifications: Modify views with INSTEAD OF triggers.

## Conclusion
PostgreSQL triggers simplify and streamline tasks by automating specific actions in response to data modifications. By grasping the distinctions between row-level, statement-level, and INSTEAD OF triggers, developers can harness their power to enhance data integrity, tracking, and overall database functionality.

Published: 2023-08-31 16:35:09

Locale support in PostgreSQL ensures applications honor cultural preferences like sorting, number formatting, and more. Let's explore the essentials of this feature:

## Automatic Initialization and Customization

- PostgreSQL uses ISO C and POSIX locale facilities from the OS.
- Locale settings are initialized during database cluster creation with initdb.
- Use --locale option with initdb to specify a different locale.

## Different Contexts for Locale Selection

1. OS Environment: Sets initial locale defaults for the cluster.
2. initdb Command-Line: Explicitly define locales during cluster creation.
3. Database-Level: Individual databases can have distinct locales.
4. Column-Level: Customize locale settings for specific table columns.
5. Query-Specific: Choose locales for particular queries.

## Locale Providers

- PostgreSQL supports multiple providers: libc (OS C library) and icu (external ICU library).
- Choose based on performance and customization needs.

## Performance Considerations

- While locales enhance localization, they can impact performance.
- They slow character handling and hinder index use with the LIKE clause.
- Use locales only when necessary.

## Troubleshooting and Contribution

- Verify OS locale configurations with the locale -a command.
- Confirm PostgreSQL's locale with the SHOW command.
- Contribute to message translations for improved localization.

## Conclusion
PostgreSQL's locale support ensures applications cater to users' cultural preferences. By understanding initialization, customization, and performance trade-offs, developers can create applications aligned with linguistic and formatting choices.
