A JSON Parser which tells you if the JSON is bad formatted or not. If it is, it will tell you which line has the error and what was expected.

• Example on CLI:

npx checkjson jsonFile.json 

Will show you the error if there is one, or it will just tell you if the JSON is well formatted.

• Example on Node:

import { jsonParse } from '@ull-esit-pl-2324/tfa-juan-rodriguez-suarez-alu0101477596';
let obj = jsonParse('jsonFile.json');

If it fails, it will throw an error with the line, column, the expected tokens and the token that was found:

try {
  let obj = jsonParse('jsonFile.json');
} catch (error) {
  console.log(error.token, error.expected, error.line, error.column);
}

A JSON to YAML converter that will convert a JSON file to a YAML file.

• Example on CLI:

npx json2yaml jsonFile.json

Will create a YAML file with the same name as the JSON file but with the .yaml extension.

With the -o flag you can specify the output file:

npx json2yaml jsonFile.json -o yamlFile.yaml

Will create a YAML file with the name yamlFile.yaml.

In both cases, if the JSON file is bad formatted, it will throw an error similar to the one in the JSON Parser.

• Example on Node:

import { jsonToYaml } from '@ull-esit-pl-2324/tfa-juan-rodriguez-suarez-alu0101477596';
jsonToYaml('jsonFile.json', 'yamlFile.yaml');

If it fails, it will throw an error similar to the one in the JSON Parser.

A function that will look for a key in a JSON file and return the value of that key.

• Example on CLI:

npx searchkey jsonFile.json key

Will print the value of all the keys matching the given key and its value.
