Building OIBus

OIBus uses pkg as its building tool.


pkg is deprecated and for now, OIBus uses a pkg fork that is compatible with latest versions of NodeJS.

Building binaries

  • npm run build:win: Build OIBus for Windows x64 architecture
  • npm run build:linux: Build OIBus for x64 linux based architectures
  • npm run build:linux-arm64: Build OIBus for ARM64 linux based platform (like Raspberry 3 B+)
  • npm run build:macos: Build OIBus for macOS Intel chips
  • npm run build:macos-arm64: Build OIBus for macOS Apple chips

Starting the binary

The following commands start the appropriate binary with data-folder as the directory where to store the caches, configuration, logs...

  • npm run start:win
  • npm run start:linux
  • npm run start:linux-arm64
  • npm run start:macos
  • npm run start:macos-arm64

Windows Installer (Windows only)

The Windows Installer can be built with Inno Setup, only on Windows platform.

However, because of some environment variables, the build action cannot be executed from Inno Setup directly. OIBus backend package.json file provide a npm command: build:win-setup. Before running it, you may need to set a few things up in order to manage the signing of the installer.

Signing OIBus Windows Installer

These commands can be used with Powershell, on a Windows system.

  1. Create a cert.conf file:
[ req ]
default_bits = 2048
default_md = sha256
distinguished_name = subject
req_extensions = req_ext
x509_extensions = req_ext
string_mask = utf8only
prompt = no

[ req_ext ]
basicConstraints = CA:FALSE
nsCertType = client, server
keyUsage = nonRepudiation, digitalSignature, keyEncipherment, dataEncipherment, keyCertSign
extendedKeyUsage= serverAuth, clientAuth
nsComment = "OIBus Cert"
subjectAltName = URI:urn:oibus,IP:

[ subject ]
countryName = FR
stateOrProvinceName = FR
localityName = Chambéry
organizationName = OI
commonName = oibus
  1. Generate CSR (Certificate Signing Request) from cert.conf file, and keep secret the private.key:
openssl req -new -newkey rsa:4096 -keyout private.key -sha256 -nodes -out oibus.csr -config cert.conf
  1. Create a local self-signed certificate
openssl x509 -req -in oibus.csr -signkey private.key -out oibus.crt
  1. Convert the cert file to PFX file
openssl pkcs12 -export -in oibus.crt -inkey private.key -out oibus.pfx -passout pass:password -name OIBus
  1. Convert PFX certificate file to base64
base64 oibus.pfx > oibus64.pfx
  1. Create the installer
$env:PFX_PASSWORD = "password" ; $env:PFX_PATH = "path" ; npm run build:win-setup
