Weave is a TUI for running multiple long-running commands at once and "weaving together" their output.

For example, have you ever wanted to run two different dev commands at once? Like:

bun run dev        # start dev server
bun run client:dev # start client bundle watcher

But you have to run them in separate terminals, tmux windows, or something? Or use & to spin them into background processes, which doesn't have great UX?

Well, now you can just do:

weave --- bun run dev --- bun run client:dev

Installation

Three options for installation:

1. Download the binary for your platform from the latest release.
2. Use bun or npm to install it:

bun add -g @luketurner/weave

3. If you are using weave in your package.json scripts, I recommend installing it as a local dependency of the package instead:

bun add --dev @luketurner/weave

If you want to test it out without installing, use bunx/npx, e.g.

bunx @luketurner/weave --help

Features

• Runs multiple commands at once in separate processes, and interleave their output together in a TUI window.
• Outputs in the log are prefixed with a colorized number like [0] to indicate which command they come from.
• Unlimited scrollback buffer (well, until you run out of memory!)
• Scroll through logs with arrow keys or your mouse wheel.
• Filter log output to individual processes.
• Restart one or all processes.
• Save output to a file.
• Works with both keyboard-driven and mouse-driven workflow -- all buttons are clickable as well as having a keybind.

Usage

# help
weave --help
# run a single command
weave --- python -m http.server
# run multiple commands simultaneously
weave --- bun run watch --- bun run client:watch --- python -m http.server

How do I do this with tmux?

You don't need weave to solve this problem, it just makes things a bit friendlier and adds some extra features.

An alternative approach with tmux:

tmux \
new-session  'bun run dev' \; \
split-window -h 'bun run client:dev' \;
