Installing

To install this package into your project, you can use the following command within your terminal

npm install --save formio-export

Usage

Creating a FormioExport instance

import FormioExport from 'formio-export';
 
let exporter = new FormioExport(component, data, options);

Using static methods

let options = {
  component: component,
  data: data,
  formio: {
    // component specific configuration
  },
  config: {
    // pdf export configuration
  }
};
 
FormioExport.toPdf(options).then((pdf) => {
  // do something
})

Configuration

The FormioExport instance can be initialized using the following configuration:

let options = {
  component: component    // the formio component
  data: data              // the formio component's data or submission
  formio: {
    ignoreLayout: true,   // should html render respect formio layouts (columns, lables positions, etc)
    emptyValue: 'n/a'     // default empty value for rendered components
  }
}

The PDF export is also configurable using the following parameters:

let config: {
  download: false,      // should the pdf file be downloaded once rendered
  filename: 'file.pdf', // the pdf file name
  margin: 10,           // the pdf file margins
  html2canvas: {
    scale: 2,           // scale factor for rendering the canvas (overall resolution of the canvas image)
    logging: false      // should console logging be enable during rendering
  },
  jsPDF: {
    orientation: 'p',   // PDF orientation - potrait / landscape
    unit: 'mm',         // measurement units used
    format: 'a4'        // paper size - can also accept custom (i.e. A4 - [210, 297])
  }
}

Simple Example

Using the FormioExport instance:

import FormioExport from 'formio-export';
 
let component = {
  type: 'form',
  title: 'Example',
  display: 'form',
  components: [
    {
      type: 'textfield',
      key: 'name',
      label: 'Name',
      input: true
    },
    {
      type: 'number',
      key: 'age',
      label: 'Age',
      input: true
    }
  ]
};
 
let submission = {
  _id: '<submission id>',
  owner: '<owner id>',
  modified: '1970-01-01T00:00:00.000Z',
  data: {
    name: 'John Doe',
    age: 25
  }
};
 
let options = {
  ignoreLayout: true
}
 
let exporter = new FormioExport(component, submission, options);
 
exporter.toHtml().then((html) => {
  document.body.appendChild(html);
});
 
let config = {
  download: false,
  filename: 'example.pdf'
};
 
exporter.toPdf(config).then((pdf) => {
  // download the pdf file
  pdf.save();
  // get the datauri string
  let datauri = pdf.output('datauristring');
})

Using the FormioExport static methods

let config = {
  component: component,
  data: submission,
  config
}
