fossa-cli - Fast, portable and reliable dependency analysis for any codebase.

Background

fossa analyzes complex codebases to generate dependency reports and license notices. By leveraging existing build environments, it can generate fast and highly-accurate results.

Features:

• Supports over 20+ languages & environments (JavaScript, Java, Ruby, Python, Golang, PHP, .NET, etc...)
• Auto-configures for monoliths; instantly handles multiple builds in large codebases
• Fast & portable; a cross-platform binary you can drop into CI or dev machines
• Generates offline documentation for license notices & third-party attributions
• Tests dependencies against license violations, audits and vulnerabilities (coming soon!) by integrating with https://fossa.io

Installation

Install on MacOS (Darwin) or Linux amd6 using curl:

curl -H 'Cache-Control: no-cache' https://raw.githubusercontent.com/fossas/fossa-cli/master/install.sh | bash

Install on Windows using cmd.exe:

@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/fossas/fossa-cli/master/install.ps1'))"

These commands will execute scripts to fetch and install the latest Github Release.

Quick Start

Run fossa -o in your repo directory to output a dependency report in JSON:

[
  {
    "Name": "fossa-cli",
    "Type": "golang",
    "Manifest": "github.com/fossas/fossa-cli/cmd/fossa",
    "Build": {
      "Dependencies": [
        {
          "locator": "go+github.com/rhysd/go-github-selfupdate$d5c53b8d0552a7bf6b36457cd458d27c80e0210b",
          "data": {
            "name": "github.com/rhysd/go-github-selfupdate",
            "version": "d5c53b8d0552a7bf6b36457cd458d27c80e0210b"
          }
        },
        ...
      ],
      ...
    }
  },
  ...
]

Run fossa and provide a FOSSA API Key to get a rich, hosted report:

export FOSSA_API_KEY="YOUR_API_KEY_HERE"

# Now, you can just run `fossa`!
fossa

# Output:
# ==========================================================
#
#    View FOSSA Report: https://app.fossa.io/{YOUR_LINK}
#
# ==========================================================

Configuration

Initialize configuation and scan for supported modules:

fossa init # writes to `.fossa.yml`

This will initialize a .fossa.yml file that looks like this:

version: 1

cli:
  server: https://app.fossa.io
  project: github.com/fossas/fossa-cli

analyze:
  modules:
    - name: fossa-cli
      path: ./cmd/fossa
      type: go

# ...

Check out our User Guide to learn about editing this file.

After configuration, you can now preview and upload new results:

# Run FOSSA analysis and preview the results we're going to upload
fossa -o

# Run FOSSA and upload results
# Going forward, you only need to run this one-liner
FOSSA_API_KEY=YOUR_API_KEY_HERE fossa

Integrating with CI

Testing for License Violations

If you've integrated with https://fossa.io, you can use fossa test to fail builds against your FOSSA scan status.

# Exit with a failing status and dump an issue report to stderr
# if your project fails its license scan
FOSSA_API_KEY=YOUR_API_KEY_HERE fossa test

# Output:
# --------------------------
# - exit status (1)
#
# * FOSSA discovered 7 license issue(s) in your dependencies:
#
# UNLICENSED_DEPENDENCY (3)
# * pod+FBSnapshotTestCase$1.8.1
# * pod+FBSnapshotTestCase$2.1.4
# * pod+Then$2.1.0
#
# POLICY_FLAG (4)
# * mvn+com.fasterxml.jackson.core:jackson-core$2.2.3
# * npm+xmldom$0.1.27
# * pod+UICKeyChainStore$1.0.5
# * gem+json$1.7.7
#
# ✖ FOSSA license scan failed: 7 issue(s) found.

Generating License Notices

To generate a license notice with each CI build, you can use the fossa report command:

# write a license notice to NOTICE.txt
fossa report --type licenses > NOTICE.txt

See this repo's NOTICE file for an example.

License data is provided by https://fossa.io's 500GB open source registry.
