Installation Instructions

There are two ways to install Easy Spaces:

• Using Salesforce DX: This is the recommended installation option. Use this option if you are a developer who wants to experience the app and the code.
• Using Unlocked Packages: This option allows anybody to experience the sample app without installing a local development environment.

Installing Easy Spaces using Salesforce DX

IMPORTANT: Because of a current issue in pre-release, make sure your project path doesn't include any of the following folder names: lwc, aura, wave. For example, DO NOT clone this repository in a folder called /Projects/lwc.

1. Set up your environment. Follow the steps in the Quick Start: Lightning Web Components Trailhead project. The steps include:

• Sign up for a Spring '19 pre-release org and enable Dev Hub functionality
• Install the pre-release version of the Salesforce CLI
• Install Visual Studio Code
• Install the Visual Studio Code Salesforce extensions, including the Lightning Web Components extension

2. Authenticate with your hub org (if not already done). The command below uses the -a flag to assign an alias that can be used in other commands:

sfdx force:auth:web:login -d -a myhuborg

3. Clone this repository:

git clone https://github.com/trailheadapps/easy-spaces-lwc
 cd easy-spaces-lwc

4. Create a scratch org and provide it with an alias (easyspaces in the command below):

sfdx force:org:create -s -f config/project-scratch-def.json -a easyspaces

5. Push source to your scratch org:

sfdx force:source:push

6. Assign two Easy Spaces permission sets to the default user:

sfdx force:user:permset:assign -n EasySpacesObjects
 sfdx force:user:permset:assign -n SpaceManagementApp

7. Load sample data:

sfdx force:data:tree:import -p ./data/Plan1.json
 sfdx force:data:tree:import -p ./data/Plan2.json

8. Open the scratch org:

sfdx force:org:open

9. Follow the instructions in the Completing the Installation section below to finish the installation.

Optional Installation Instructions

This repository contains several files that are relevant if you want to integrate modern web development tooling to your Salesforce development processes, or to your continuous integration/continuous deployment processes.

Code formatting

Prettier is a code formatter used to ensure consistent formatting across your code base. To use Prettier with Visual Studio Code, install this extension from the Visual Studio Code Marketplace. The .prettierignore and .prettierrc files are provided as part of this repository to control the behavior of the Prettier formatter.

Code linting

ESLint is a popular JavaScript linting tool used to identify stylistic errors and erroneous constructs. To use ESLint with Visual Studio Code, install this extension from the Visual Studio Code Marketplace. The .eslintignore file is provided as part of this repository to exclude specific files from the linting process in the context of Lighning Web Components development.

Pre-commit hook

This repository also comes with a <package.json> file that makes it easy to set up a pre-commit hook that enforces code formatting and linting by running Prettier and ESLint every time you git commit changes.

To set up the formatting and linting pre-commit hook:

1. Install Node.js if you haven't already done so
2. Run npm install in your project's root folder to install the ESLint and Prettier modules (Note: Mac users should verify that Xcode command line tools are installed before running this command.)

Prettier and ESLint will now run automatically every time you commit changes. The commit will fail if linting errors are detected. You can also run the formatting and linting from the command line using the following commands (check out <package.json> for the full list):

npm run lint:lwc
npm run prettier

Code Highlights

Dynamic Flows and Local Action Components

The spaceDesigner and reservationHelper Aura components render flow interviews dynamically, by using the lightning:flow base component. You can see the customerDetails and designFormCmp Aura components at work as screens in these dynamic flows. Both of these components use the functionality of the lightning:availableForFlowScreens interface to control flow navigation actions.

See this blog post for more detail about custom flow navigation and dynamic flow interviews.

The Aura components used as Lightning Flow screens also use a convention in the markup of their design files, to help developers better track how attributes are being used by flow interviews. See the customerDetails and designFormCmp component design files for examples.

Object-Agnostic Design

The customerList and customerTile Lightning web components can display information from Contact objects or Lead objects. In the Reservation Manager app page, both Lead and Contact variations are used in order to create a unified workspace:

The customerList Lightning web component uses a design attribute to allow for users working in Lightning App Builder to control which object an instance of the Lightning web component should display:

This is just one example of object-agnostic design at work in Easy Spaces. See this blog post for more detail about this pattern.

Console Navigation and Background Refresh

Easy Spaces uses the Lightning Console JavaScript API and the Lightning web component NavigationMixin to control user navigation between tabs and subtabs. You can see the lightning:workspaceAPI component at work in the openRecordAction Aura component, which enables flow interviews to navigate users to a new subtab. The reservationHelperAura and spaceDesignerAura components use the lightning:navigationItemAPI component to refresh custom Lightning Page tabs in the background as a user works. You can get more detail about using the Workspace API in your components in this blog post.

Lightning web components use the NavigationMixin control navigation behavior. You can see the NavigationMixin at work in the relatedSpaces, customerTile and reservationTile Lightning web components. The customerList and reservationList Lightning web components use Lightning Data Service wired methods to display data from Apex. This allows the platform to handle provisioning and managing a client-side cache. These components programmatically refresh that wired data, based on user interactions with sibling Aura components. Check out the code in reservationList and customerList Lightning web component Javascript files.

Modular Design and Unlocked Packaging

Easy Spaces illustrates how to organize application metadata into granular units or modules. This approach is reflected in the design patterns at work throughout the application, like the use of object-agnostic components. But you'll also see this at work in the structure of the Easy Spaces repo itself.

The Easy Spaces application is made of several, interdependent unlocked packages. The dependecies between the Easy Spaces packages are listed in the sfdx-project.json file for this repo.

You can also explore the contents of each package by looking at the related package folder within this repo. The path attribute entries in the sfdx-project.json show which folder contains the metadata for a particular package.
