# Integrating custom gulp tasks to SharePoint Framwork toolchain

## Summary
SharePoint client-side development tools use gulp as the build process task runner to:

- Bundle and minify JavaScript and CSS files.
- Run tools to call the bundling and minification tasks before each build.
- Compile LESS or SASS files to CSS.
- Compile TypeScript files to JavaScript.

One common task you would want add to the SharePoint Framework toolchain is to integrate your custom gulp tasks and execute them.

This sample shows how to integrate custom gulp tasks using the [gulp-image-resize](https://www.npmjs.com/package/gulp-image-resize) task that resizes images.

Read the following documentation for detailed information on integrating gulp tasks in SharePoint Framework:

- [Integrate custom gulp tasks in the SharePoint Framework toolchain](https://docs.microsoft.com/sharepoint/dev/spfx/toolchain/integrate-gulp-tasks-in-build-pipeline)
