Concurrently

Run multiple processes concurrently, with support for cargo.

Written in Rust with ☕

Install with Cargo

bash $ cargo install concurrently

Getting Started

Create a tasks.toml file in the root of your project:

```toml [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:

bash $ cargo concurrently

Config

These configs are optional, and can be used with all tasks.

| Config | Type | | |---------|--------|----------------------------------------------------------------------------------| | prepare | String | Runs a command before starting the task. | | delay | String | Waits before starting the task. This can be in the format of "1s", "100ms", etc. | | retries | Number | Retries this task before exiting all other tasks. |

Shell Task

Shell task runs a shell command.

| Config | Type | | |---------|-----------------|-------------------------------| | command | String or Array | Runs the command as the task. |

Cargo Task

Cargo tasks are built using cargo with cargo build -p <name> where name is the name of the task.

cargo must be set to true for a task to be a cargo task.

| Config | Type | | |----------|----------|----------------------------------------------------------------------------------------| | cargo | Bool | If set to true, treats this task as a cargo crate. The crate will be built on startup. | | release | Bool | Builds for release. | | features | [String] | Array of feature flags. |
