💥 Regression Report

I think it related to the refactor of #423

Debug mode no longer work like README.md describe.

fastify/fastify#3995

Steps to Reproduce

const debugCompiled = fastJson({
  title: 'default string',
  type: 'object',
  properties: {
    firstName: {
      type: 'string'
    }
  }
}, { debugMode: true })

console.log(debugCompiled) // it is an array of functions that can create your `stringify` function
console.log(debugCompiled.toString()) // print a "ready to read" string function, you can save it to a file

const rawString = debugCompiled.toString()
const stringify = fastJson.restore(rawString) // use the generated string to get back the `stringify` function
console.log(stringify({ firstName: 'Foo', surname: 'bar' })) // '{"firstName":"Foo"}'

Expected Behavior

No response

I recommend we provide a function for standalone mode.

I'm sorry. There is a lack of tests here, so it's easy to break something. I will take a look at this.

@climba03003 I took a quick look at this problem. #423 didn't break it. The restore function compiles stringify function from debugCompiled but never from debugCompiled.toString().

fast-json-stringify/test/debug-mode.test.js

Line 47 in b57abf1

const compiled = fjs.restore(debugMode)

It breaks because of multiple of PR. #382 is the first breaking piece.
fastify build script is actually building a standalone code which the debug mode should do.

Serializer is never exported, so no matter how I modify and match the current implementation of debug mode.
It will never be success.

Nevermind, I created a PR for the fastify use-case.
#460

debug mode can be use to run inside the script.
standalone mode provide code that can be run directly.
