Usage: |
|
$ run-p [--help | -h | --version | -v] |
|
$ run-p [OPTIONS] <tasks> |
|
|
|
Run given npm-scripts in parallel. |
|
|
|
<tasks> : A list of npm-scripts' names and Glob-like patterns. |
|
|
|
Options: |
|
--aggregate-output - - - Avoid interleaving output by delaying printing of |
|
each command's output until it has finished. |
|
-c, --continue-on-error - Set the flag to continue executing other tasks |
|
even if a task threw an error. 'run-p' itself |
|
will exit with non-zero code if one or more tasks |
|
threw error(s). |
|
--max-parallel <number> - Set the maximum number of parallelism. Default is |
|
unlimited. |
|
--npm-path <string> - - - Set the path to npm. Default is the value of |
|
environment variable npm_execpath. |
|
If the variable is not defined, then it's "npm." |
|
In this case, the "npm" command must be found in |
|
environment variable PATH. |
|
-l, --print-label - - - - Set the flag to print the task name as a prefix |
|
on each line of output. Tools in tasks may stop |
|
coloring their output if this option was given. |
|
-n, --print-name - - - - Set the flag to print the task name before |
|
running each task. |
|
-r, --race - - - - - - - Set the flag to kill all tasks when a task |
|
finished with zero. |
|
-s, --silent - - - - - - Set 'silent' to the log level of npm. |
|
|
|
Shorthand aliases can be combined. |
|
For example, '-clns' equals to '-c -l -n -s'. |
|
|
|
Examples: |
|
$ run-p watch:** |
|
$ run-p --print-label "build:** -- --watch" |
|
$ run-p -sl "build:** -- --watch" |
|
$ run-p start-server start-browser start-electron |
