Turbo Static

Leverages rust-analyzer to build a complete view into the static dependency graph for your turbo tasks project.

How it works

• find all occurrences of #[turbo_tasks::function] across all the packages you want to query
• for each of the tasks we find, query rust analyzer to see which tasks call them
• apply some very basis control flow analysis to determine whether the call is made 1 time, 0/1 times, or 0+ times, corresponding to direct calls, conditionals, or for loops
• produce a cypher file that can be loaded into a graph database to query the static dependency graph

Usage

This uses an in memory persisted database to cache rust-analyzer queries. To reset the cache, pass the --reindex flag. Running will produce a graph.cypherl file which can be loaded into any cypher-compatible database.

# pass in the root folders you want to analyze. the system will recursively
# parse all rust code looking for turbo tasks functions
cargo run --release -- ../../../turbo ../../../next.js
# now you can load graph.cypherl into your database of choice, such as neo4j
docker run \
    --publish=7474:7474 --publish=7687:7687 \
    --volume=$HOME/neo4j/data:/data \
    neo4j
