File structure

|
|_ /examples -> Contains various faulty use cases to test the validation logic
|_ /schemas -> Contains the HIP412@1.0.0 schema 
|_ /validators -> Contains different additional validator helper functions on top of the `jsonschema` validation package

Run the project with your NFT metadata

To install dependency jsonschema, run:

npm install

To run the project:

node index

If you want to add your own example:

1. Add your NFT metadata as a new file in the /examples folder.
2. Add a code snippet to the index.js file at the bottom, make sure to update the file import. This snippet will run all the checks against your NFT metadata.

const myexample = require("./examples/myexample.json"); // change import to your example

let result = validator.validate(myexample, schema);
console.log(`\n\n>>> Example`);
if (result.errors.length === 0) console.log("JSON Schema Validation: Success");
if (result.errors.length > 0) errorParser(result.errors);
console.log(attributesValidator(myexample));
console.log(localizationValidator(myexample));
console.log(SHA256Validator(myexample));
