GroupDocs.Parser for Node.js via Java does not require Microsoft Office or any other third-party software. It needs Node.js, Java and, at installation time, a native build toolchain for the java bridge package.

GroupDocs.Parser for Node.js via Java runs on any 64-bit operating system where Node.js and Java are available, including:

• Windows 10, Windows 11
• Windows Server 2016, 2019, 2022, 2025
• Microsoft Azure

• Ubuntu, Debian, CentOS, RHEL, AlmaLinux, Rocky Linux, Amazon Linux, OpenSUSE and other modern distributions

• macOS 12 Monterey and later (Intel and Apple Silicon)

Use a current LTS version of Node.js: Node.js 20 LTS or later is recommended.

GroupDocs.Parser for Node.js via Java requires Java 8 (1.8) or later. Java 11, 17 and 21 LTS are supported; Java 17 LTS is recommended.

Install a JDK, not only a JRE, on the machine where you run npm install: the java bridge package compiles a native module against the JDK’s JNI headers. A JRE is enough at runtime if the application is deployed with already built node_modules.

Make sure Java can be found:

• Set JAVA_HOME to the JDK root folder.
• Add JAVA_HOME/bin to PATH.

Windows (PowerShell):

$env:JAVA_HOME = "C:\Program Files\Java\jdk-17"
$env:Path = "$env:JAVA_HOME\bin;$env:Path"

Linux/macOS (Bash):

export JAVA_HOME=/usr/lib/jvm/java-17-openjdk
export PATH="$JAVA_HOME/bin:$PATH"

The java package is built with node-gyp during installation. Depending on your operating system, install the following tools (see the Installation section of node-gyp for full details).

• Python 3
• make
• A C/C++ compiler toolchain, such as GCC

On Debian/Ubuntu:

sudo apt-get update
sudo apt-get install -y build-essential python3

• Python 3
• Xcode Command Line Tools (xcode-select --install)

• Python 3
• Visual Studio Build Tools with the Desktop development with C++ workload

With Chocolatey:

choco install python visualstudio2022-workload-vctools -y

npm install downloads the GroupDocs.Parser JAR file from releases.groupdocs.com in the package’s postinstall step, using curl. Make sure curl is available and the machine can reach that host, or see Installation for a manual download.

At runtime no network access is required, except when you use a metered license or parse emails from a mail server.

To extract text with correct character mapping and to render page previews correctly, install the fonts used in your documents on the machine. On Linux servers and in containers, install a comprehensive font set (for example, DejaVu or Noto fonts) and any corporate fonts you use.

Example for a Debian/Ubuntu-based image:

apt-get update \
  && apt-get install -y --no-install-recommends \
     curl ca-certificates build-essential python3 openjdk-17-jdk-headless fonts-dejavu \
  && rm -rf /var/lib/apt/lists/*

Then install the package in your application:

npm install @groupdocs/groupdocs.parser
