Make your purchase decisions only on the basis of generally available products and features.

Create a Salesforce DX Project

A Salesforce DX project has a specific structure and a configuration file that identifies the directory as a Salesforce DX project.
  1. Change to the directory where you want the DX project located.
  2. Create the DX project. 
    1sf project generate --name MyProject
    If you don’t specify an output directory with the --output-dir flag, the project directory is created in the current location. You can also use the --default-package-dir flag to specify the default package directory to target when syncing source to and from the org. If you don’t indicate a default package directory, this command creates a default package directory, force-app.

    Use the --template flag to specify what your project initially looks like. Each template provides a complete directory structure that takes the guesswork out of where to put your source. If you choose --template empty, your project contains these sample configuration files to get you started.

    • .forceignore
    • config/project-scratch-def.json
    • sfdx-project.json
    • package.json

    If you choose --template standard, your project also contains these files that are especially helpful when using Salesforce Extensions for VS Code. If you don’t specify the --template flag, the project generate command uses the standard template.

    • .gitignore: Makes it easier to start using Git for version control.
    • .prettierrc and .prettierignore: Make it easier to start using Prettier to format your Aura components.
    • .vscode/extensions.json: Causes Visual Studio Code, when launched, to prompt you to install the recommended extensions for your project.
    • .vscode/launch.json: Configures Replay Debugger, making it more discoverable and easier to use.
    • .vscode/settings.json: By default, this file has one setting for excluding certain files and folders in searches and quick open. You can change this value or add other settings.

    If you choose --template analytics, you get all the helpful basic and VS Code files. But the default package directory contains fewer directories, such as for storing Analytics template bundles. /force-app/main/default/waveTemplates) and a few other metadata types, such as Apex classes and LWC components.

Example

1sf project generate --name mywork --template standard
1sf project generate --name mywork --default-package-dir myapp-source

Next steps:

  • (Optional) Register the namespace with the Dev Hub org.
  • Configure the project (sfdx-project.json). If you use a namespace, update this file to include it.
  • Create a scratch org definition that produces scratch orgs with the features you need for your project. The config directory of your new project contains a sample scratch org definition file (project-scratch-def.json).
