Isom

Take your task runner further

If you have a tasks.json file running isom or npx isom will run the task you pass in or the start task.

Lifecyle

For every task you can define you can also have a pre post as well as a cleanup associated with it.

* pre runs before the main command.
* command runs if the pre command is successful
* post runs if the command was successful
* clean runs regardless of the success or failure of the other tasks

Example

The tasks.json file

``json
{
"prebuild": ["npx eslint ./src", "npx jest", "rm -rf dist"],
"build": "npx webpack --config ./src/webpack/prod.config.js --mode production",
"postbuild": ["npm publish", "npx publisher", "node ./src/tasks/announce.js"],
"cleanupbuild": "rm -rf dist"
}
`

Then from the command line you can either run npx isom build or if installed globally isom build

You can use it within your scripts so in your package.json

`json
{
"build": "isom build"
}
`

Parallel Tasks

In addition to single items, a task can be an array of items. If the array is a pretask they execute in a series, however if the array is the main task to run, the tasks run in parallel.

$3

`json
{
"predev": [
"docker-compose -f ./docker/docker-compose.yml up --detach",
"node ./src/scripts/delay.js",
"npx knex migrate:latest",
"npx knex seed:run"
],
"dev": [
"nodemon ./src/server/index.js",
"webpack-dev-server --config ./src/webpack/dev.config.js --mode development"
]
}
`

Then from command line

`bash
isom dev
`

Then the predev tasks run in order then then dev` task executes both tasks at the same time.
