How to use csv-to-custom-json options

Options

To use options, you need to add a third paramters which is an object with options.

Example :

const parsedFile = await parseFile("myfile.csv", schema, {
    debug: true,
});

Informations for tests

  • For options, when it's writed boolean, in reality, it can be any true value of javascript. Same for false.

  • command to run test

Test can be run with options :

npm -s run test -- -n test/callBack_force.test.js callBack_force.test.js

Legend :

  • -s is to silent npm
  • -- is used to pass the -n parameters to the test.js file
  • -n is used to allow only useful log
  • test/callBack_force.test.js and callBack_force.test.js are here to demonstrate that you can omit the test/ in the string

Debug

  • name: debug
  • default: false
  • value: boolean: true or false

This options show the parsed result of your schema (can be useful sometimes)

This options also allow log from the function (example, a mistake)
