node-scripting

Functions that simplify node utility scripts

The design goal of this package is to make simple things simple. Making hard things possible is not one of the goals.

API

main

Usage:

main(module, async () => {
  // ... Script code
});

Script code will be executed when running module directly, but will not be executed when importing module. As a bonus it's easy to use await in the script code. Future: parsing args and passing them into callback.

print

Basically console.log with small improvements: returns first argument as a result (making debugging easier, e.g. run(print(getCommand()), print(getOptions()))). Also, when called with one argument, uses 99 for util.inspect depth instead of the default.

exec

Essentially promisified exec from 'child_process', but with significant differences:

• takes one string or array of strings as first argument and no second argument
• returns concatenation stderr and stdout encoded to utf8
• when first argument is array, commands are executed sequentially and result is array
• new lines are stripped from command text

exec.io

Essentially execSync from 'child_process', but with some differences:

• takes one string or array of strings as first argument and no second argument
• stdio is only in 'inherit' mode
• prints command before execution
• always returns undefined

fetch

Reexport from 'node-fetch'.

fs

Reexport from 'fs-extra'.

env.text

Reads from value from environment, undefined returned as empty string.

env.bool

Reads from value from environment converting it to boolean.

env.int

Reads from value from environment converting it to number.
