Dreamhouse Lightning Web Components Sample Application

IMPORTANT: This is the new Lightning Web Components version of the Dreamhouse sample application. If you are looking for the Aura version, click here.

DreamHouse is a sample application that demonstrates the unique value proposition of the Salesforce platform for building Employee Productivity and Customer Engagement apps.

Installation Instructions

There are two ways to install Dreamhouse:

• 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 an Unlocked Package: This option allows anybody to experience the sample app without installing a local development environment.

Installing Dreamhouse 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.

• Install the pre-release version of the Salesforce CLI
• Install Visual Studio Code
• Install the Visual Studio Code Salesforce extensions, including the Lighting Web Components extension

2. If you haven't already done so, authenticate with your Spring '19 hub org and provide it with an alias (spring19hub):

sfdx force:auth:web:login -d -a spring19hub

3. Clone this repository:

git clone https://github.com/dreamhouseapp/dreamhouse-lwc
 cd dreamhouse-lwc

4. Create a scratch org and provide it with an alias (dreamhouse):

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

5. Push the app to your scratch org:

sfdx force:source:push

6. Assign the dreamhouse permission set to the default user:

sfdx force:user:permset:assign -n dreamhouse

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
