Any advise on JSON schema validator using Suitescript ?

what are you looking to validate?

Shopify order payload

like what aspect of the schema do you need though

Validate all properties present in payload

if you want to validate a key in the schema, you could do something like

var x = Object.keys(context);
if (x.indexOf('keyname') != -1) {
// do something
}

does that works for nested keys and it's arrays

{
  "Order": {
    "ID": 234,
    "items": [
      {
        "sku": "3454JJ",
        "quantity": 1
      },
      {
        "sku": "3454JJ",
        "quantity": 1
      }
    ]
  }
}

you would have to index into the nested objects etc so instead of context, you could do context.items.length() to see if there is anything in the items array

We use ajv for JSON Schema validation. https://ajv.js.org/

how did you wrap up in suitescript ? @Richard Tanner

its AMD compatible. You can put the js file into your file cabinet and then include it in the define of script.

could you please send me link where can I download file ?

If you are going to run it serverside, make sure you set the logger option to false. Otherwise it will error trying to use console.log. Use something like this when you initialize it.

new Ajv({ logger: false });

whats is your define function in script ?

Here is a proof of concept suitelet to get you started. I copied the example code from the AJV website. It assumes the AJV script file is placed in SuiteScripts/Test and called ajv7.js.

/**
 * @NApiVersion 2.1
 * @NScriptType Suitelet
 */
define(['SuiteScripts/Test/ajv7'],
    
    (Ajv) => {
        /**
         * Defines the Suitelet script trigger point.
         * @param {Object} scriptContext
         * @param {ServerRequest} scriptContext.request - Incoming request
         * @param {ServerResponse} scriptContext.response - Suitelet response
         * @since 2015.2
         */
        const onRequest = (scriptContext) => {
            const ajv=new Ajv({allErrors: true,logger: false});

            const schema = {
                type: "object",
                properties: {
                    foo: {type: "integer"},
                    bar: {type: "string"}
                },
                required: ["foo"],
                additionalProperties: false
            }
            const validate = ajv.compile(schema);

            const data = {
                foo: 1,
                bar: "abc"
            }

            const valid = validate(data);

            scriptContext.response.write(JSON.stringify(valid));

        }

        return {onRequest}

    });

is there way you could please share that ajv7.js file ?

yes
