Simple-react-native-form NPM

Simple React Form

Simple React Form is a library to make reusable form components in React and React Native and works great with Meteor

This is just a framework, you must create the form components that you will use.

If you use material-ui you are lucky, because I published a material-ui set of components. simple-react-form-material-ui.

Made for Meteor, but works without Meteor too. This package was inspired by aldeed's autoform.

To use with react native check here

Installation

Install the base package

npm install --save simple-react-form

If you use material-ui install that package too

npm install --save simple-react-form-material-ui

If you don't use material-ui check the contributions if there is a package for you.

Example

import React from 'react'
import {Form, Field} from 'simple-react-form'
import DatePicker from 'simple-react-form-material-ui/lib/date-picker'
import Text from 'simple-react-form-material-ui/lib/text'

class PostsCreate extends React.Component {

  constructor(props) {
    super(props)
    this.state = {}
  }

  render() {
    return (
      <div>
        <Form state={this.state} onChange={changes => this.setState(changes)}>
          <Field fieldName='name' label='Name' type={Text}/>
          <Field fieldName='date' label='A Date' type={DatePicker}/>
        </Form>
        <p>
          My name is {this.state.name}
        </p>
      </div>
    )
  }
}

Docs

Using with state

In this example, the current value of the form will be stored in this.state

import React from 'react'
import {Form, Field} from 'simple-react-form'
import DatePicker from 'simple-react-form-material-ui/lib/date-picker'
import Text from 'simple-react-form-material-ui/lib/text'

class PostsCreate extends React.Component {

  constructor(props) {
    super(props)
    this.state = {}
  }

  render() {
    return (
      <div>
        <Form state={this.state} onChange={changes => this.setState(changes)}>
          <Field fieldName='name' label='Name' type={Text}/>
          <Field fieldName='date' label='A Date' type={DatePicker}/>
        </Form>
        <p>
          My name is {this.state.name}
        </p>
      </div>
    )
  }
}

Use with Meteor Simple Schema

Automatic forms creation with aldeed/meteor-simple-schema and React.

Allow `srf` field for schemas

With simple-schema you must define the object attributes that are not the basics.

Just add this code once in your app.

SimpleSchema.extendOptions({
  srf: Match.Optional(Object)
})

Basic Example

Schema

import {Meteor} from 'meteor/meteor'
import Textarea from 'simple-react-form-material-ui/lib/textarea'
import Text from 'simple-react-form-material-ui/lib/text'

const Posts = new Meteor.Collection('posts')

Posts.attachSchema({
  title: {
    type: String,
    srf: {
      type: Text
    }
  },
  body: {
    type: String,
    label: 'Content',
    srf: {
      type: Textarea
    }
  }
})

export default Posts

An insert form.

import React from 'react'
import {Form} from 'simple-react-form'
import Posts from '../../collections/posts'

class PostsCreate extends React.Component {
  render() {
    return (
      <div>
        <h1>Create a post</h1>
        <Form
        collection={Posts}
        type='insert'
        ref='form'
        onSuccess={(docId) => FlowRouter.go('posts.update', { postId: docId })}/>
        <RaisedButton label='Create' onTouchTap={() => this.refs.form.submit()}/>
      </div>
    )
  },
}

An update form.

import React from 'react'
import {Form, Field} from 'simple-react-form'
import Posts from '../../collections/posts'

class PostsUpdate extends React.Component {
  render() {
    return (
      <div>
        <h1>Post update</h1>
        <Form
        collection={Posts}
        type='update'
        ref='form'
        doc={this.props.post}>
          <Field fieldName='title'/>
          <Field fieldName='body'/>
        </Form>
        <RaisedButton primary={true} label='Save' onTouchTap={() => this.refs.form.submit()}/>
      </div>
    )
  }
}

Custom Input Types

React Simple Form is built from the idea that you can create custom components easily.

Basically this consist in a component that have the prop value and the prop onChange. You must render the value and call onChange passing the new value when the value has changed.

You can also pass props to this components setting them in the srf parameter of the simple-schema object:

import UploadImage from '../components/my-fields/upload'

Post.attachSchema({
  picture: {
    type: String,
    srf: {
      type: UploadImage,
      squareOnly: true
    }
  }
})

Or simply in the field while rendering:

import UploadImage from '../components/my-fields/upload'

<Field fieldName='picture' type={UploadImage} squareOnly={true}/>

Creating the field type

You must create a React component. Check the props that are passed by default here

import React from 'react'

export default class UploadImage extends React.Component {
  render() {
    return (
      <div>
        <p>
          {this.props.label}
        </p>
        <img src={this.props.value} />
        <TextField
        value={this.props.value}
        hintText='Image Url'
        onChange={(event) => this.props.onChange(event.target.value)} />
        <p>
          {this.props.errorMessage}
        </p>
      </div>  
    );
  }
}

You can view the full list of props here.

Props that are not define in propTypes will be stored in this.passProps and deleted from propTypes.

React Native

With React Native the api is the same, but you must pass the option useFormTag={false} to the form.

Example:

You must create all your field types (Maybe someone makes a package in the future!)

import React from 'react'
import {View, TextInput} from 'react-native'

export default class TextFieldComponent extends React.Component {

  render () {
    return (
      <View>
        <TextInput
        style={{height: 40, borderColor: 'gray', borderWidth: 1}}
        onChangeText={this.props.onChange}
        value={this.props.value}/>
      </View>
    )
  }
}

Render the form in the component you want

import Text from '../components/my-fields/text'

<Form state={this.state} onChange={changes => this.setState(changes)} useFormTag={false}>
  <View>
    <Field fieldName='email' type={Text}/>
    <Field fieldName='password' type={Text}/>
  </View>
</Form>
