@json section defines HTTP routes that return application/json content


  • Each route begins with get, post, put, patch or delete followed by the desired path
  • Dashes and underscores are not allowed
  • Maximum length of 100 characters
  • Optional Express-style URL parameters denoted with colons (:)


This .arc file defines some typical JSON routes:


get /notes          
get /notes/:noteID
post /notes           # create a note
put /notes/:noteID    # update a note
delete /notes/:noteID # delete a note

The .arc above generates the following REST functions:

├── json
│   ├── get-notes/
│   ├── get-notes-000noteID/
│   ├── post-notes/
│   ├── put-notes-000noteID/
│   └── delete-notes-000noteID/
├── .arc
└── package.json

Note: The route /notes/:noteID corresponding handler deliberately looks a bit weird with the triple 000. This is so you can quickly differentiate URL params from URL parts. The Lambda deploy targets follow suit:

  • testapp-staging-get-notes-000noteID
  • testapp-production-get-notes-000noteID
