CLI command to generate a valid graphQl schema from the faker one about graphql-faker

[johannchopin]

@IvanGoncharov I already implement the script for my use case so there won't be a lot of work there for you. What do you think of this idea? Could I have a green light to open a PR?

Sadly the maintainers (@IvanGoncharov, @RomanHotsiy) aren't really active on this repo so I won't waste time by opening PR. Here is the simple getSchemaFromContent helper that takes a faker shema string as a parameter and return it without the faker directives:

const FAKER_DIRECTIVE_MATCHER = / @fake\((.*?)\)\n/g
const EXAMPLES_DIRECTIVE_MATCHER = / @examples\(values: \[(.*?)\]\)\n/g
const LISTLENGTH_DIRECTIVE_MATCHER = / @listLength\((.*?)\)\n/g
const MATCHERS = [FAKER_DIRECTIVE_MATCHER, EXAMPLES_DIRECTIVE_MATCHER, LISTLENGTH_DIRECTIVE_MATCHER]

const replaceAll = (str: string, find: string, replace: string): string => {
  return str.split(find).join(replace)
}

const getAllFakerDirectivesFromContent = (content: string): string[] => {
  let directives: string[] = []
  MATCHERS.forEach((matcher) => {
    directives = [...directives, ...Array.from(content.matchAll(matcher), (m) => { return m[0] })]
  })

  return directives
}

export const getSchemaFromContent = (content: string): string => {
  const directives = getAllFakerDirectivesFromContent(content)

  directives.forEach((directive) => {
    content = replaceAll(content, directive, '\n')
  })

  return content
}

Hope it will help you @ojczeo 👍

@johannchopin that's sounds interesting. Could you share it somewhere?
