? What's the name of your application? spike-todo
create spike-todo/
info change the working directory to spike-todo
...
Next steps:
Change directory to your app
$ cd spike-todo
Create a model in your app
$ slc loopback:model
Optional: Enable StrongOps monitoring
$ slc strongops
Run the app
$ slc run .

links:
- mongo
