Experience
A Hays Plugin for IntelliJ IDEA
A plugin that allows users to easily create code, files, and folders from defined templates. It boosts users' productivity by shortening the time needed to create new files and folders, reducing the challenge of rewriting the same base code while maintaining the code structure and naming convention. Available templates include Laravel, Angular, React with JavaScript, TypeScript, and MUI, and React Native with JavaScript and TypeScript.
A React Hook Form
A stateful form hook and API to easily control React and React Native forms and their fields with minimal JSX code. It supports Joi validation and error handling and has easy-to-use predefined fields or can use form APIs to handle custom component states. The stateful form tracks values, errors, and touched and focused fields. It also features a complete API to set and reset values, submit forms, force validate, disable, and make read-only forms.
An OpenAPI/Swagger Auto Generator for Laravel API Documentation
A Laravel package to generate technical API documentation with zero doctrine annotations. For every API handler, you only need to use a package data transfer object that handles request data serialization, automap and define validation schema, and add a hash attribute like # [ReturnTypeSingleOf(‘user’, User::class)]. The package is now able to read your code and generate the required OpenAPI schema to build Swagger UI.
