Deployment

1. Create in root folder .env file and set next required parameter:

KEY_PASSWORD=...                # [required] password from private key file

Also you can set another environment variables:

DEBUG=app                   # turn on service logs into console; default: app
NODE_ENV=...                # dev|prod; default: prod
PORT=...                    # port number where you want to start server; default: 3000
WRITE_INTO_FILE=...         # true|false; if you need to store all data into files into {root}/resources; default: false
KEY_FILE_NAME=...           # name of private key file, which you will put into {root}/resources; default: key.dat
CERTIFICATE_FILE_NAME=...   # name of certificate file, which you will put into {root}/resources; default: certificate.cer
SIGNED_DATA_FILE_NAME=...   # name of generated EDS file, which you will get to {root}/resources; default: signedData.p7s
PARSED_DATA_FILE_NAME=...   # file name of parsed response content from SFS; this file will write into {root}/resources; default: decrypted.txt

2. Copy key.dat and certificate.cer files to {root}/resources

3. Execute:

npm i
npm run start

Also, there is another command exists for starting watcher of server code changes:

npm run debug

Docker mode

1. Do the 1st and 2nd steps from Deployment section (see above).

2. Run from root folder:

sudo ./docker.sh

3. Now you can call server from docker container with:

curl http://0.0.0.0:3100
