Latest Package Version Lookup

Query the deps.dev API to get the latest stable version of open-source packages. This is faster and more reliable than searching the web or guessing version numbers, and it catches deprecated packages before you install them.

Supported Ecosystems

When to Use

• Adding a new dependency and need the current version
• Updating package.json, requirements.txt, Cargo.toml, etc. to latest
• Checking whether a package has been deprecated
• Comparing versions across multiple packages at once

When NOT to Use

• Private or internal packages (deps.dev only indexes public registries)
• Looking up documentation or usage examples (use context7 instead)

Workflow

DO NOT read script source code. Run scripts directly and use --help for usage.

1. Identify the ecosystem from project files:

   • package.json or node_modules → npm
   • requirements.txt, pyproject.toml, setup.py → pypi
   • go.mod, go.sum → go
   • Cargo.toml → cargo
   • pom.xml, build.gradle → maven

python3 scripts/get-versions.py <system> <pkg1> [pkg2] ...

Run python3 scripts/get-versions.py --help if unsure about usage.

Examples

python3 scripts/get-versions.py npm express lodash @types/node
python3 scripts/get-versions.py pypi requests django flask
python3 scripts/get-versions.py go github.com/gin-gonic/gin

Output Format

TSV with header. One line per package:

package	version	published	status
express	5.0.0	2024-09-10	ok
lodash	4.17.21	2021-02-20	ok

Status values: ok, deprecated, not found, error: <detail>.

Rules

• Use the script instead of manual curl — it handles URL encoding (especially for scoped npm packages like @types/node) and fetches multiple packages in parallel, so it's both easier and faster.
• Flag deprecated packages — if the status column says deprecated, tell the user and suggest an alternative if you know one.
• Batch lookups when possible — the script accepts multiple package names in one call, which is faster than running it once per package.
