Material-ui-pickers: No default export

[slavikdenis]

After upgrading to version ^1.0.0 there is an typescript error.

Environment

| Tech | Version |
|---------------------|---------|
| material-ui-pickers | ^1.0.0 |
| material-ui | ^3.3.1 |
| React | ^16.6.0 |
| Browser | irrelevant |
| Peer library | "date-fns": "2.0.0-alpha.16" |

Error

/node_modules/material-ui-pickers/utils/date-fns-utils/index.d.ts (2,8): Module ''date-fns/locale/en-US'' has no default export.

Workaround

Until this is fixed, you can use "skipLibCheck": true option in your tsconfig.json.

Could you enable esModuleInterop option in ts config?

[slavikdenis]

Yep, that solves the problem. Could you mention it in docs or somewhere else, because the default for this option is false. (https://www.typescriptlang.org/docs/handbook/compiler-options.html)

PR is appreciated

[slavikdenis]

Would not be better to fix it for date-fns as it is suggested for moment in this PR https://github.com/dmtrKovalenko/material-ui-pickers/pull/712 ?

I don't think so. Default behaviour is wrong and makes ecosystem broken. Imported namespace cannot be callable.
