Stitch

Stitch is a tool used to pull together definitions written in JSON with the main focus on simplicity.

• Stitch will base64 JavaScript files that are named appropriately (and reside in a code folder) and insert them into your resulting definition.
• Stitch will insert any form folder definition.json files into your result definition.

At its heart, it's a tool used to help write and maintain complex JSON files that would otherwise be incomprehensible.

Installation

npm: npm i rexlabs/stitch

yarn: yarn global add rexlabs/stitch

Requirements

For environment requirements, see the package.json.

File structure

The folder that contains your definition.json is the entry point for stitch to work out of.

You can also have a code and form folder located in your entry point directory, this enables stitch to take advantage of advanced base64 encoding (JavaScript) and JSON file combining (forms).

definition-folder
|-- definition.json
|-- code
|   |-- my_step.js
|-- form
    |-- my_step.json

To take advantage of the base64 encoding component of stitch, you'll need to name your JavaScript files located inside your code folder the same as the step that they reside in, for example:

definition.json

{
      "name": "loop",
      "triggers": "check_loop",
      "description": "Loop until I say to stop",
      "label": "Loop step - do something",
      "type": "task",
      "function": {
        "format": "base64",
        "code": "",
        "modules": ["lodash"]
      }
}

loop.js

const _ = require("lodash");

/**
 * @param {Object} context
 * @returns {Object}
 */
module.exports = function(context) {
  return {
    should_loop: _.get(context, "state.meta.steps.loop.loop_index", 0) < 3
  };
};
