An efficient instrumentation and profiling framework for Graal.js.

Getting Started

Get the mx build tool:

git clone https://github.com/graalvm/mx.git

Use mx to download a JDK for building GraalVM and set the JAVA_HOME environment variable accordingly:

mx fetch-jdk --java-distribution labsjdk-ce-11
export JAVA_HOME=PATH_TO_THE_DOWNLOADED_JDK

Get dependent projects and build:

mkdir workspace-nodeprof
cd workspace-nodeprof
git clone https://github.com/Haiyang-Sun/nodeprof.js.git
cd nodeprof.js
mx sforceimports
mx build

Run tests:

mx test-all

Detailed explanation can be found in the Tutorial;

Goals

The goals of NodeProf are:

• Use AST-level instrumentation which can benefit from the partial evaluation of the Graal compiler and have a much lower overhead compared to source-code instrumentation framework such as Jalangi
• Compatible to analysis written in Jalangi detail.
• Comprehensive coverage for NPM modules and Node.js libraries.
• Compliant to the latest ECMAScript specification (thanks to Graal.js)
