lotsadeps

lotsadeps crawls the Go module proxy index to discover public Go modules, resolves each to its latest version, validates each module's go.mod, and generates a go.mod file with a large number of require directives.

This is useful for testing tooling that deals with dependency-heavy Go modules.

Usage

go run main.go [-max <n>] [-workers <n>] [-batch <n>] [-o <output>]

Flag	Default	Description
-max	0 (unlimited)	Maximum number of index entries to fetch
-workers	20	Number of concurrent workers for module validation
-batch	2000	Number of index entries per request
-o	go.mod	Output file path

Example

# Crawl 10,000 index entries and write results to generated.gomod
go run main.go -max 10000 -o generated.gomod

How it works

1. Fetches batches of entries from index.golang.org/index
2. For each module, resolves the latest version via proxy.golang.org
3. Validates the module path and version using golang.org/x/mod
4. Deduplicates and writes unique require directives to the output file
