The Form.io PDF Solution is a powerful tool with two options: PDF Server and PDF Server Plus. Please see the below description of each to see which aligns best with the requirements of the Application being built.
The Use Case: Starting with dynamic, JSON-driven, responsive webforms that users are filling out and submitting within an application, I want to print out a PDF of the web form submission.
The Use Case: Forms are required to be on a pixel-perfect PDF background with a dynamic JSON form overlay on top of the PDF.
PDF-First forms can also be presented to the user as responsive web forms, but enable the ability to print the Submission to the pixel-perfect PDF background.
A common deployment command for the PDF server looks as follows.
docker run -itd \
-e "LICENSE_KEY=YOURLICENSE" \
-e "MONGO=mongodb://mongo:27017/formio" \
-e "FORMIO_S3_SERVER=minio" \
-e "FORMIO_S3_PORT=9000" \
-e "FORMIO_S3_BUCKET=formio" \
-e "FORMIO_S3_KEY=CHANGEME" \
-e "FORMIO_S3_SECRET=CHANGEME" \
--network formio \
--link formio-mongo:mongo \
--link formio-minio:minio \
--restart unless-stopped \
--name pdf-server \
-p 4005:4005 \
Which uses the following Environment Variables.
Now that you have the PDF server operational as well as the API Server, the next thing that needs to happen is to configure the Form.io Portal to use the correct DNS url for the PDF Server url. This is necessary because the "internal" DNS url is used within the Enterprise Server configurations, and we now need to let the Portal know how to directly communicate to the PDF Server. To set this up, you will first need to navigate to your Project Settings, and then click on PDF Server configuration page. Here you will then need to provide the Public DNS url to the pdf server as follows.
Configure the Public DNS url to the PDF server in your project settings.
Once you have done this, you should now be able to upload an existing PDF form, where it will then convert that PDF document into a Form.io webform overlay on top of that PDF form.
The PDF Server Plus includes Auto-Conversion of existing fillable and non-fillable PDF Forms. Using AWS Textract for PDF First Forms that do not have any metadata that can be read for conversion, the PDF Server will auto-detect Field Input Types, Labels and more and convert the PDF to a dynamic Form.io Form!
After setting up PDF Server it is possible to integrate with AWS Textract to enable Formfields Recognition feature.
- 1.Create IAM role with policies:
Save ARN, it will be used later.
- 2.Create AWS Simple Notification Service topic and save its ARN
- 3.Add the following environment variables to configuration:
4. After starting PDF environment with new environment variables, go to previously created SNS topic page and create a subscription:
- Left topic ARN as it is
- In Protocol field choose HTTP
- In Endpoint field type *public URL of your environment*/pdf/pdf/sns
In case of misconfiguration, you will not be able to upload a PDF file.
5. After configuration you can check the status of formfields recognition by visiting URL
