Other packages similar to gatsby-plugin-typescript

typescript

The typescript package is the official TypeScript compiler and language service. It provides the core TypeScript functionality, including type-checking and transpilation. Unlike gatsby-plugin-typescript, it does not integrate directly with Gatsby but can be used in any JavaScript project.

babel-plugin-transform-typescript

The babel-plugin-transform-typescript package is a Babel plugin that allows you to use TypeScript with Babel. It strips out type annotations and compiles TypeScript code to JavaScript. This plugin can be used in conjunction with Gatsby's Babel setup, but it does not provide the same level of integration as gatsby-plugin-typescript.

ts-loader

The ts-loader package is a TypeScript loader for Webpack. It allows you to compile TypeScript files using the TypeScript compiler within a Webpack build process. While it can be used in a Gatsby project, it requires additional configuration compared to the seamless integration provided by gatsby-plugin-typescript.
