Configuration

HiGlass App can be configured at build time using config.json. config.json contains the default configuration. To adjust it copy it to config.dev.json, config.prod.json, or config.local.json. dev is used in developmental mode, prod is picked up in production, and local can be used for local testing. The config is overwritten in the following order: default, dev, prod, local.

Folder Structure

HiGlass App is based on react-create-app and implements the following folder structure:

• /build [Do not edit.]

  Contains the build files.

• /config

  Contains the build configs for webpack and converting Markdown into JSX. Except the JSX, the files are derived from react-create-app.

• /node_modules [Do not edit.]

  Contains thrid party libraries.

• /public

  Contains the public index files of HiGlassApp.

• /scripts

  Contains node scripts for webpack and converting Markdown into JSX. Except the JSX, the files are derived from react-create-app.

• /src

  Entry point for the application source.

  • /actions

    Flat folder containing Redux actions. All actions should be exported in the index.js.

  • /components

    Flat folder containing presentational components. See Dan's article for a comparison between presentational and container components.

  • /configs

    Flat folder containing config files. Configs should host all constant variables.

  • /containers

    Flat folder containing container components. See Dan's article for a comparison between presentational and container components.

  • /factories

    Flat folder containing factory functions. See Eric's article for an introduction to factory functions.

  • /hocs

    Flat folder containing higher-order components. See the React docs for an introduction.

  • /images

    Flat folder containing images.

  • /reducers

    Flat folder containing Redux reducers.

  • /styles

    Flat folder containing generic style components. Note: this is kind of arbitrary but I like to separate reusable CSS classes from index.scss such that I can quickly drop them into other apps.

  • /utils

    Flat folder containing utility functions. (Utility function must be pure and should not have any state.)

  • /views

    Flat folder containing all view components. (View components are just like presentational components with the only difference that they are associated to a specific URL. This separation is again arbitrary but I like having all views separated as I consider them uncomposable. Only Main should import views.)
