How can I import custom styled-components in react

Question

I have Form.js file in styled-ui folder.

Form.js

// input
export const FormControl = styled.input`
  border-radius: 3px;
  border: 1px solid #b2bec3;
  padding: 0 10px;
  height: 34px;
  font-size: 15px;
  outline: 0;
  width: 100%;
`

And I import the Form.js file in styled-ui/index.js like this.

import * as Form from './Form'
import * as Section from './Section'

export default {
  ...Form,
  ...Section
}

This is my conatiner file where import styled-components

import {
  FormControl
} from '@/styled-ui'

After then When I use this,

<FormControl></FormControl>

I got error that '@/styled-ui' does not contain an export named 'FormControl'. However, When I use like this It works well.

import styled from '@/styled-ui'
`<styled.FormControl></styled.FormControl>`

And I'm using webpack for development and production

{
            test: /\.css$/,
            use: [
              require.resolve('style-loader'),
              {
                loader: require.resolve('css-loader'),
                options: {
                  importLoaders: 1,
                },
              },
              {
                loader: require.resolve('postcss-loader'),
                options: {
                  // Necessary for external CSS imports to work
                  // https://github.com/facebookincubator/create-react-app/issues/2677
                  ident: 'postcss',
                  plugins: () => [
                    require('postcss-flexbugs-fixes'),
                    autoprefixer({
                      browsers: [
                        '>1%',
                        'last 4 versions',
                        'Firefox ESR',
                        'not ie < 9', // React doesn't support IE8 anyway
                      ],
                      flexbox: 'no-2009',
                    }),
                  ],
                },
              },
            ],
          },

I'm so confused now. please tell me how can I fix this problem?

import * as Form from './Form'

...

export default {
  ...Form,
  ...Section
}

is in your case, the same than writing

import * as Form from './Form'

...

export default {
  FormControl: Form.FormControl,
  ...Section
}

That's why <styled.FormControl> works fine.

What you can probably do in your index.js file is something like

export * from './Form'

Is it only way to solve this problem? There are many components in my Form.js

Arnaud Christ Over a year ago

I just edited my answer. I think you can use export *

kkangil Over a year ago

you mean just export like this? export * from './Section' export * from './Form' It doesn't work for me.
