dynamic import is stage 4 (but still doesn't work)

[dtudury]

What version of standard?
13.1.0

What operating system, Node.js, and npm version?
macOS 10.14.1, v10.16.0, 6.9.0

What did you expect to happen?

54:  const _installMap = new Map()
55:  async function _installComponent (path) {
56:    if (!_installMap.has(path)) {
57:      _installMap.set(path, import(path))
58:    }
59:    return _installMap.get(path)
60:  }

works on 83.29% of browsers and is in stage 4 of the TC39 process.
I expect standard to consider it valid code

What actually happened?

$ ./node_modules/.bin/standard
standard: Use JavaScript Standard Style (https://standardjs.com)
  /Users/dtudury/Repos/dtudury/rememberism/docs/controller.js:57:27: Parsing error: Unexpected token import

I know this has been reported before (#751) but that issue is closed and locked (because dynamic import was stage 3... but now it's stage 4)

We're currently waiting on support from ESLint for dynamic import. See this issue: eslint/eslint#11803 And here's a in-progress PR: eslint/eslint#11983

Once that's been released, we'll update and finally get support :) In the meantime, you can use babel-eslint as a custom parser (instructions for how to set this up are in the README)

sorry, yeah, I wouldn't have assumed it was your issue. however, searching the error message led to the closed issue where you kind of implied you'd fix it if it was in stage 4 😄

it sounds like the only purpose this issue serves is as a nag to merge the eslint version when it's released. (but maybe it feels good to close issues so I won't close it myself)

Happy to leave this issue open as a reminder to watch the ESLint issue :)

[dtudury]

I just did a quick check, should this be working now? seems like everything got merged in

[feross]

@dtudury In order to get support, we need to update to ESLint 6.2.0 or later. There's a PR for that here: #1376 but it is blocked on this bug in babel-eslint:

• eslint/eslint#12117
• babel/babel-eslint#791

Once that's resolved, I'll update the version.
