{{alias}}( files, [options,] clbk )
|
||
|
|
Executes scripts in parallel.
|
||
|
|
|
||
|
|
Relative file paths are resolved relative to the current working directory.
|
||
|
|
|
||
|
|
Ordered script output does not imply that scripts are executed in order. To
|
||
|
|
preserve script order, execute the scripts sequentially via some other
|
||
|
|
means.
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
files: Array<string>
|
||
|
|
Script file paths.
|
||
|
|
|
||
|
|
options: Object (optional)
|
||
|
|
Options.
|
||
|
|
|
||
|
|
options.cmd: string (optional)
|
||
|
|
Executable file/command. Default: `'node'`.
|
||
|
|
|
||
|
|
options.concurrency: integer (optional)
|
||
|
|
Number of scripts to execute concurrently. Script concurrency cannot
|
||
|
|
exceed the number of scripts. By specifying a concurrency greater than
|
||
|
|
the number of workers, a worker may be executing more than `1` script at
|
||
|
|
any one time. While not likely to be advantageous for synchronous
|
||
|
|
scripts, setting a higher concurrency may be advantageous for scripts
|
||
|
|
performing asynchronous tasks. If the script concurrency is less than
|
||
|
|
the number of workers, the number of workers is reduced to match the
|
||
|
|
specified concurrency. Default: `options.workers`.
|
||
|
|
|
||
|
|
options.workers: integer (optional)
|
||
|
|
Number of workers. Default: number of CPUs minus `1`.
|
||
|
|
|
||
|
|
options.ordered: boolean (optional)
|
||
|
|
Boolean indicating whether to preserve the order of script output. By
|
||
|
|
default, the `stdio` output for each script is interleaved; i.e., the
|
||
|
|
`stdio` output from one script may be interleaved with the `stdio`
|
||
|
|
output from one or more other scripts. To preserve the `stdio` output
|
||
|
|
order for each script, set the `ordered` option to `true`. Default:
|
||
|
|
`false`.
|
||
|
|
|
||
|
|
options.uid: integer (optional)
|
||
|
|
Process user identity.
|
||
|
|
|
||
|
|
options.gid: integer (optional)
|
||
|
|
Process group identity.
|
||
|
|
|
||
|
|
options.maxBuffer: integer (optional)
|
||
|
|
Max child process `stdio` buffer size. This option is only applied when
|
||
|
|
`options.ordered = true`. Default: `200*1024*1024`.
|
||
|
|
|
||
|
|
clbk: Function
|
||
|
|
Callback to invoke after executing all scripts.
|
||
|
|
|
||
|
|
Examples
|
||
|
|
--------
|
||
|
|
> function done( error ) { if ( error ) { throw error; } };
|
||
|
|
> var files = [ './a.js', './b.js' ];
|
||
|
|
> {{alias}}( files, done );
|
||
|
|
|
||
|
|
// Specify the number of workers:
|
||
|
|
> var opts = { 'workers': 8 };
|
||
|
|
> {{alias}}( files, opts, done );
