The SendGrid Template Manager communicates with the SendGrid API to manage your Design Library and Dynamical Templates (a.k.a. Transactional Templates) on the SendGrip website.

A drawback of SendGrid is that it is easy to create new Templates from a Design, but a painstaking manual task to apply changes to existing Templates. With this tool you can automatically synchronize changes to any Design from the Design Library to your Templates.

The tool merges the content of a Template Content Version (TCV) with a Design into a new Template Version on your SendGrid account.

The Design contains your entire email layout (header, footer, ...) and should contain an empty Text module somewhere. This is where the Template Content Version will be inserted.

Template Content Versions are versions of a Template with the name __content__. The entirety of the TCV will be inserted into the Design.

The result of the merger will be stored in a new/updated version in the same Template.

That's it!

You can install SGTM globally:

npm install i -g sgtm
sgtm --help

or use npx:

npx sgtm --help

To use the tool, you have to provide a SendGrid API key. The tool will look for the key in the .env file, or you can pass the --key option to any command:

sgtm list --key=<SGKEY>

sgtm list lists the currently available Designs and Templates in your account.

$> sgtm list
