@thing-description-playground/json-spell-checker v1.0.1

@thing-description-playground/JSON-SPELL-CHECKER

This package provides spell-checking support for JSON files when a JSON Schema is given. You can find more information about the Thingweb-Playground here.

Limitations:

• There is limited nested spell checking. Some of the $ref definitions can be nested infinitely, therefore spell checking stops at the first detection of recursive nesting.
• This tool mainly developed for Thing Descriptions. Even though it can be used for all JSON Schemas, it may not cover all the rules of a schema. For example 'if, else, then' rule of Open API schema is not supported yet but this functionality could be added in the future.

  <script src="./node_modules/@thing-description-playground/json-spell-checker/dist/web-bundle.min.js"></script>

• First configure your spell checker using (similarityThreshold should be between 0 and 1 and try to set maxLengthDifference low in case you need quick typo evaluation):

jsonSpellChecker.configure(yourSchema, similarityThreshold, maxLengthDifference)

• Or just set schema and use default values for similarityThreshold (0.85) and maxLengthDifference (2)

jsonSpellChecker.configure(yourSchema)

• Then call checkTypos function with your stringified JSON file to find typos

jsonSpellChecker.checkTypos(stringifiedJsonFile)
