loader]), you
can do as follows:

```json
{
  "scripts": {
    "test": "cross-env TS_NODE_COMPILER_OPTIONS={\\\"module\\\":\\\"commonjs\\\"} node some_file.test.ts"
  }
}
```

Pay special attention to the **triple backslash** `(\\\)` **before** the
**double quotes** `(")` and the **absence** of **single quotes** `(')`. Both of
these conditions have to be met in order to work both on Windows and UNIX.

## `cross-env` vs `cross-env-shell`

The `cross-env` module exposes two bins: `cross-env` and `cross-env-shell`. The
first one executes commands using [`cross-spawn`][cross-spawn], while the second
one uses the `shell` option from Node's `spawn`.

The main use case for `cross-env-shell` is when you need an environment variable
to be set across an entire inline shell script, rather than just one command.

For example, if you want to have the environment variable apply to several
commands in series then you will need to wrap those in quotes and use
`cross-env-shell` instead of `cross-env`.

```json
{
  "scripts": {
    "greet": "cross-env-shell GREETING=Hi NAME=Joe \"echo $GREETING && echo $NAME\""
  }
}
```

The rule of thumb is: if you want to pass to `cross-env` a command that contains
special shell characters _that you want interpreted_, then use
`cross-env-shell`. Otherwise stick to `cross-env`.

On Windows you need to use `cross-env-shell`, if you want to handle
[signal events](https://nodejs.org/api/process.html#process_signal_events)
inside of your program. A common case for that is when you want to capture a
`SIGINT` event invoked by pressing `Ctrl + C` on the command-line interface.

## Windows Issues

Please note that `npm` uses `cmd` by default and that doesn't support command
substitution, so if you want to leverage that, then you need to update your
`.npmrc` to set the `script-shell` to powershell.

## Inspiration

I originally created this to solve a problem I was having with my npm scripts in
[angular-formly][angular-formly]. This made contributing to the project much
easier for Windows users.

## Other Solutions

- [`env-cmd`](https://github.com/toddbluhm/env-cmd) - Reads environment
  variables from a file instead
- [`@naholyr/cross-env`](https://www.npmjs.com/package/@naholyr/cross-env) -
  `cross-env` with support for setting default values
