After checking the prerequisites, follow these simple steps to install and use Vue Form:

# clone the repo
$ git clone https://github.com/ditdot-dev/vue-flow-form.git myproject

# go into app's directory and install dependencies:
$ cd myproject
```

If you use npm:

```shell
$ npm install

# serve with hot reload at localhost:8080 by default.
$ npm run serve

# build for production
$ npm run build
```

If you use yarn:

```shell
$ yarn install

# serve with hot reload at localhost:8080 by default.
$ yarn serve

# build for production
$ yarn build
```

Made with [Vue.js](https://vuejs.org/)

## Usage as npm package

If you don't already have an existing Vue project, the easiest way to create one is to use [Vue CLI](https://cli.vuejs.org/):

```shell
$ npm install -g @vue/cli
# OR
$ yarn global add @vue/cli
```

And then create a project (refer to [Vue CLI documentation](https://cli.vuejs.org/guide/) and [issue tracker](https://github.com/vuejs/vue-cli/issues) for potential problems on Windows):

```shell
$ vue create my-project
$ cd my-project
```

To add Vue Flow Form as a dependency to your Vue project, use the following:

```shell
$ npm install @ditdot-dev/vue-flow-form --save
```

And then in your App.vue file:

```html
<template>
  <flow-form v-bind:questions="questions" v-bind:language="language" />
</template>

<script>
  // Import necessary components and classes
  import FlowForm, { QuestionModel, QuestionType, ChoiceOption, LanguageModel } from '@ditdot-dev/vue-flow-form'

  export default {
    name: 'example',
    components: {
      FlowForm
    },
    data() {
      return {
        language: new LanguageModel({
          // Your language definitions here (optional).
          // You can leave out this prop if you want to use the default definitions.
        }),
        questions: [
          // QuestionModel array
          new QuestionModel({
            title: 'Question',
            type: QuestionType.MultipleChoice,
            options: [
              new ChoiceOption({
                label: 'Answer'
              })
            ]
          })
        ]
      }
    }
  }
</script>

<style>
  /* Import Vue Flow Form base CSS */
  @import '~@ditdot-dev/vue-flow-form/dist/vue-flow-form.css';
  /* Import one of the Vue Flow Form CSS themes (optional) */
  @import '~@ditdot-dev/vue-flow-form/dist/vue-flow-form.theme-minimal.css';
  /* @import '~@ditdot-dev/vue-flow-form/dist/vue-flow-form.theme-green.css'; */
