Opensrc

Opensrc is a command-line utility that fetches and caches package source code, returning a local path for developers and coding agents to search or inspect implementations.

Practical overview

When it fits

Use Opensrc when understanding a dependency requires reading implementation code rather than relying only on its name or exposed types.

Who it is for

  • Developers investigating how a dependency is implemented.
  • Coding-agent workflows that need package source as additional context.

Documented uses

  • Fetch package source from supported registries or GitHub.
  • Search dependency code with local command-line tools.
  • Open specific source files for implementation-level inspection.
Before you choose

Requirements & limits

The getting-started instructions require Node.js 18 or later and Git for cloning repositories.

  • The CLI documentation names npm, PyPI, crates.io, and GitHub as supported source registries.
  • The first path lookup fetches source; subsequent lookups use the cached path.
  • Opensrc retrieves source and exposes a path; searching and reading are done with other command-line tools.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Opensrc and inspect package source

Set up the CLI and use its returned source path with shell tools to search or read a package implementation.

Before you start

  • Node.js 18 or later
  • Git for cloning repositories
  • A shell and search or file-reading tools such as rg, grep, find, or cat

Steps

  1. Install the CLI with the command below.

    Documented command
    npm install -g opensrc

  2. Pass a package reference to opensrc path; the first use fetches the source and returns its cached path on later calls.

  3. Use the returned path with a shell tool, such as rg "parse" $(opensrc path zod) to search or cat $(opensrc path zod)/src/types.ts to read a file.

  4. For other documented sources, use references such as pypi:requests, crates:serde, or vercel/next.js.

Expected outcome

A local cached source path that can be searched or used to open package files.

Guide limitations

  • The documented examples cover source retrieval and local inspection; they do not describe automated analysis of the retrieved code.
