Form.io File Upload Server
This library provides an Upload Server/Proxy for use with the Form.io File Component and URL configuration. This allows for Private file upload and downloads by sending Authentication requests to the Form.io API Server to determine if a user has permissions to upload or download based on their access to either Submit the form, or fetch the Submission JSON respectively.
This library can be ran within 3 different environments.
- Locally using Node.js
- Docker container
- AWS Lambda
Running locally with Node.js
In order to run this server locally, you can type the following within your terminal.
npm install node index
Running within Docker
To run this with docker, you can use the following commands.
docker run -itd \ -e "PORT=4100" \ -e "MAX_UPLOAD_SIZE=16mb" \ -e "DEBUG=*" \ -e "PROVIDERS=file,alfresco" \ -e "UPLOAD_DIR=" \ -e "ALFRESCO_USER=admin" \ -e "ALFRESCO_PASS=admin" \ -e "ALFRESCO_HOST=http://127.0.0.1:8082" \ --restart unless-stopped \ --name formio-upload \ -p 4100:4100 \ formio/formio-upload
Running within AWS Lambda
Before you can run with AWS Lambda, you must first install Claudia.
npm install claudia -g
Next, you will want to configure your access credentials to the AWS CLI. You can do this by following the instructions @ https://claudiajs.com/tutorials/installing.html
Once you have access setup, you can now modify the deploy scripts within
package.json to change where this script will be deployed. Once you have made changes to the
deploy script within
package.json, you can now run the following to deploy this within AWS Lambda using the deploy script.
npm run deploy
You must use Environment variables to configure the runtime operation of this server. When running this server locally using Node.js, you can set the Environment variables within the
.env file. These variables are defined as follows.
|PORT||The port you wish to run the server on.||4100|
|MAX_UPLOAD_SIZE||The maximum upload size for files being uploaded.||16mb|
|PROVIDERS||Determines which upload providers are enabled. This is a CSV of the providers you wish to enable. For example "file,alfresco" will enable both local file uploads as well as Alfresco ECM uploads.||file|
|UPLOAD_DIR||When using the "file" provider, this is the local upload base directory.||providers/uploads|
|ALFRESCO_USER||When using the Alfresco provider, this is the user account to log into the Alfresco ECM||admin|
|ALFRESCO_PASS||When using the Alfresco provider, this is the user account password to log into the Alfresco ECM||admin|
|ALFRESCO_HOST||When using the Alfresco provider, this is the Alfresco ECM server URL||http://127.0.0.1:8082|
Configure Form Upload
Now that you have the server running, you can configure a Form.io Form with a new File component.
Within the configuration of this File component, you will need to set the file upload type to URL and then provide the URL of this service. You can decide which upload provider to use based on the path you provide to the url of the running server.
- http://localhost:4100/file - Uses the local file upload provider.
- http://localhost:4100/alfresco - Uses the Alfresco ECM upload provider.
You will also need to make sure you check Private Download. Your configuration should look something like the following.
The upload will now function against this server.
