This is a very simple demo. It just shows importing isomorphic-git and using it to print the list of branches on a repo.

git clone https://github.com/isomorphic-git/examples
cd typescript-node
npm install

npm run build
npm start

Obviously you can copy and paste this as a starter, but it was pretty straightforward to create:

mkdir typescript-node
cd typescript-node
npm init -y
npm install -D typescript @types/node
npm install isomorphic-git
./node_modules/.bin/tsc --init

Then I...

• changed the compilerOptions.outDir property and added an include property to tsconfig.json
• added the build and start scripts to package.json
• wrote src/index.ts
