  • CLI with arguments (supports piped input)
  • REPL
  • Piped I/O
  • require or import as module
• Compatibility
  • Supports any npm module
• Quick
  • Graphical application composition
  • Automated npm package managemnt for Gesso functions
• Configurable
  • Configure Gesso shell to customize the developer experience
• Extensible
  • Custom command parsers with middleware
• Deployable
  • Remove developer Gesso functions to package application for deployment
• Integrations
  • Visual Studio Code extension (WIP)

gesso can install and run Gesso functions. The functions installed in a Gesso workspace define the capabilities of gesso.

To boostrap gesso for developing applications, run the following commands:

gesso install @gesso/function # Installs the default Gesso function.
gesso install @gesso/new      # Installs the "new" command to create functions.
gesso install @gesso/package  # Installs the "package" command to package applications.

Running gesso with no arguments and no piped input runs Gesso in interactive mode. Interactive mode is essentialy a REPL.

Run gesso to open Gesso in interactive mode which presents an input prompt:

$ echo "Hello"
Hello
$ text-to-speech "Hello there"

gesso and each gesso-function can be run from the command line.

gesso echo hello

gesso echo uuid-generator

gesso text-to-speech "Hello from Gesso."

gesso text-to-speech --input.text "Hello from Gesso."

gesso text-to-speech --input.text "Hello from Gesso." --input.voice Alex

Input arguments can be specified without the input. prefix when only input arguments are specified.

gesso text-to-speech --text "Hello from Gesso." --voice Alex

echo "echo hello" | gesso

echo "hello" | gesso echo

To deploy, just remove the functions/init, functions/new, functions/edit, and functions/install functions (makes read-only).

Gesso editing functions can be reinstalled by anyone that checks out the project, so they're considered reserved folder names (defined in default gesso.json file).

Gesso can run on one or more machines (i.e., a cluster).
