(breaking change)

Going to start out by saying babel-generator is the package that takes an AST from the babel plugin/presets and returns a string (your file). As a compile file you probably shouldn't be caring that much about the options here. You're going to minify it in prod as well and it's not the source code where you would use eslint, prettier, etc.

Thus out of the options currently in generator - https://github.com/babel/babel/tree/master/packages/babel-generator#options, the quotes one doesn't make sense because the others have to do with code coverage, minification, or sourcemaps.

This also would fix #4803 (fixing the issue by removing the option)

• Comment below you are going to do this (for others to know)
• Read CONTRIBUTING.md
• Check you are on 7.0 branch with git checkout 7.0 and then make a branch off of that to PR
• Join our slack if you haven't already if you need more immediate help or just comment in this issue/PR
• remove quotes option from babel-generator (readme, src, tests)

  • babel/packages/babel-generator/src/index.js

    Line 61 in 292c3ca

    quotes: opts.quotes || findCommonStringDelimiter(code, tokens),

  • babel/packages/babel-generator/src/printer.js

    Line 25 in 672adba

    quotes: "single" | "double";

  • might not have tests in my initial check which is probably why custom quotes option is broken down #4803
