pre-push

pre-push is a pre-push hook installer for git. It will ensure that
your npm test (or other specified scripts) passes before you can push your
changes. This all conveniently configured in your package.json.

But don't worry, you can still force a push by telling git to skip the
pre-push hooks by simply pushing using --no-verify.

It's advised to install the pre-push module as a devDependencies in your
package.json as you only need this for development purposes. To install the
module simply run:

``
npm install --save-dev pre-push
`

or

`
yarn add -D pre-push
`

To install it as devDependency. When this module is installed it will override
the existing pre-push file in your .git/hooks folder. Existing
pre-push hooks will be backed up as pre-push.old in the same repository.

pre-push will try to run your npm test command in the root of the git
repository by default unless it's the default value that is set by the npm
init script.

But pre-push is not limited to just running your npm test's during the
push hook. It's also capable of running every other script that you've
specified in your package.json "scripts" field. So before people push you
could ensure that:

- You have 100% coverage
- All styling passes.
- JSHint passes.
- Contribution licenses signed etc.

The only thing you need to do is add a pre-push array to your package.json
that specifies which scripts you want to have ran and in which order:

`js
{
"name": "437464d0899504fb6b7b",
"version": "0.0.0",
"description": "ERROR: No README.md file found!",
"main": "index.js",
"scripts": {
"test": "echo \"Error: I SHOULD FAIL LOLOLOLOLOL \" && exit 1",
"foo": "echo \"fooo\" && exit 0",
"bar": "echo \"bar\" && exit 0"
},
"pre-push": [
"foo",
"bar",
"test"
]
}
`

In the example above, it will first run: npm run foo then npm run bar and
finally npm run test which will make the push fail as it returns the error
code 1. If you prefer strings over arrays or prepush without a middle
dash, that also works:

`js
{
"prepush": "foo, bar, test"
"pre-push": "foo, bar, test"
"pre-push": ["foo", "bar", "test"]
"prepush": ["foo", "bar", "test"],
"prepush": {
"run": "foo, bar, test",
},
"pre-push": {
"run": ["foo", "bar", "test"],
},
"prepush": {
"run": ["foo", "bar", "test"],
},
"pre-push": {
"run": "foo, bar, test",
}
}
`

The examples above are all the same. In addition to configuring which scripts
should be ran you can also configure the following options:

- silent Don't output the prefixed pre-push: messages when things fail
or when we have nothing to run. Should be a boolean.
- colors Don't output colors when we write messages. Should be a boolean.
- template Path to a file who's content should be used as template for the
git push body.

These options can either be added in the pre-push/prepush object as keys
or as "pre-push.{key} key properties in the package.json:

`js
{
"prepush.silent": true,
"pre-push": {
"silent": true
}
}
`

It's all the same. Different styles so use what matches your project. To learn
more about the scripts, please read the official npm` documentation:
