Hammer

Hammer is a no-config cli tool for running concurrent tasks with monorepo support. Monorepo tooling should be as simple as it can. Unfortunately, the current tooling is overly complex and can lead to a lot of time spent configuring and debugging, when you should be worried about writing your code.

You can think of Hammer as a lightweight alternative for turborepo. Currently, it only supports JS/TS projects. In the future it could expand and have a larger number of languages supported.

The hammer bin

The hammer binary is hammer's CLI. It aims to be as simple as it can get.

Syntax: bash hammer <SCRIPT> [OPTS]

Example:

bash hammer dev Runs all the workspaces projects "hammer:dev" scripts.

Disabling the prefix

By default, hammer will look up for all the scripts containing the prefix hammer: in package.json, thus making it easy to gradually adopt the tool and run only the scripts you want using it. If you don't want this, just use the --no-prefix flag and hammer will look for the dev script directly:

bash hammer dev --no-prefix Runs all workspace projects "dev" scripts.

alias: -n

Filtering

You can filter which projects should be targeted by hammer:

bash hammer dev --filter web Will only run the dev script of the project that contains a package.json with the "name" being "web"

alias: -f
