Run multiple processes concurrently, with support for cargo.
Written in Rust with ☕
Install with Cargo
$ cargo install concurrently
Getting Started
Create a tasks.toml
file in the root of your project:
[tasks.client]
workspace = true # Run the client cargo workspace member
retries = 3 # Retry 3 times before exiting
delay = "1s" # Wait 1 second before running
[tasks.server]
workspace = true # Run the server cargo workspace member
release = true # Run in --release mode
[tasks.db]
command = [
"docker",
"run",
"postgres",
]
Now you can simply run concurrently:
$ cargo concurrently
