Deploy to Salesforce DX is a tool that can deploy an application to Salesforce directly from Github using
the tools provided by Salesforce DX. When you login with your Dev Hub
credentials, you generate an access token that is used to create a scratch org and run all subsequent operations.
This access token is only used during the deployment process and is stored in a browser cookie; it is not stored anywhere else.
Deploy to Salesforce DX is a community project intended to help developers explore Salesforce DX. There is no official support, but you can log an issue at
https://github.com/wadewegner/deploy-to-sfdx/issues. While every effort
is made to ensure it operates without error, please use at your own risk.
