Packages

Mission

The aim of Piximi’s multi-package organization is three-fold:

• maintain a DRY codebase;

• ensure generic interfaces between features; and

• simplify the bootstrapping process for new contributors.

DRY

If you find yourself duplicating code, it’s time to create a new package. Packages like @piximi/components, @piximi/store, and @piximi/types exemplify this habit. @piximi/store, for example, includes Redux actions for creating, updating, and deleting images that are used by multiple packages. Because each of these packages use the same @piximi/store actions, we can ensure the behavior between packages is consistent.

Organization

We use Yarn workspaces to organize our code into a modern mono repo (10 min video tutorial: Yarn Workspace) and lerna for handling the workspace (10 min video tutorial: Lerna).

This repository includes both the Piximi web app (packages/piximi) and the handful of discrete @piximi sub-packages (packages/@piximi/*) written concurrently or alongside the web app. The packages included in the packages directory are versioned together and simultaneously published to the NPM package repository.

Working on a package

Maybe you just experienced a bug or you want to add a feature to Piximi.

Within a package we use storybook to work on UI components

yarn storybook

Creating a new package

Storybook

Packages with React components should include a storybook command and a .storybook directory with an appropriate Storybook configuration.

Most packages will only have one story that corresponds to the package’s one exported component. For example, image-viewer-dialog has one story for the ImageViewerDialog component. Likewise, fit-classifier-dialog has one story for the FitClassifierDialog component. A noteworthy exception are packages that export more than one component, e.g. @piximi/components has a story for each of its exported components.
