ES6 -> ES5 in npm package

[kachkaev]

I'm using create-react-app and its webpack config does not apply babel to stuff in node_modules. The app works in dev mode because Chrome understands ES6 pretty well already, but when I run yarn build, this error shows up:

Failed to compile.

static/js/main.582ff19c.js from UglifyJs
SyntaxError: Unexpected token: operator (>) [./~/neat-csv/index.js:6,0]

The reason is => in index.js, which is not expected. Could you please move from ES6 to ES5 in the published version?

Thanks for the wrapper! Saves some time re-implementing it in every new project :–)

I temporary copied index.js to my src, so it goes through babel now:

// import neatCsv from 'neat-csv';
import neatCsv from './lib/neat-csv';

In short, no. Longer answer: sindresorhus/ama#446 (comment)

Your package, your rules :–)

For those who also use create-react-app or a similar framework with a preconfigured webpack, here is what you can do:

1. Create src/lib/neat-csv.js:

   /* eslint-disable */
   'use strict';
   const intoStream = require('into-stream');
   const csvParser = require('csv-parser');
   const getStream = require('get-stream');
   
   module.exports = (input, opts) => {
     if (typeof input === 'string' || Buffer.isBuffer(input)) {
       input = intoStream(input);
     }
   
     return getStream.array(input.pipe(csvParser(opts)));
   };

2. replace import neatCsv from 'neat-csv'; with import neatCsv from '../lib/neat-csv' (the path may vary depending on your current file location).

3. npm rm -S neat-csv; npm i -S into-stream csv-parser get-stream

4. Enjoy :–)
