An INI format parser & serializer.
Sections are treated as nested objects.
Section-less items are treated as globals.
Consider an INI file such as the following:
; This comment is being ignored scope = global [database] user = dbuser password = dbpassword database = use_this_database [paths.default] datadir = /var/lib/data array[] = first value array[] = second value array[] = third value
You can read, modify and write it like so:
import { writeFile , readFile } from 'node:fs/promises'
import { stringify , parse } from 'ini'
// Read INI file as text
let text = await readFile(`./Original.ini`,{
encoding : 'utf-8'
})
// Parse text data to object
const config = parse(text)
// Modify data object
config.scope = 'local'
config.database.database = 'use_another_database'
config.paths.default.tmpdir = '/tmp'
delete config.paths.default.datadir
config.paths.default.array.push('fourth value')
// Stringify data object
text = stringify(config,{
section : 'section'
})
// Write INI file as text
await writeFile(`./Modified.ini`,text)
The written file will contain the following:
[section] scope=local [section.database] user=dbuser password=dbpassword database=use_another_database [section.paths.default] tmpdir=/tmp array[]=first value array[]=second value array[]=third value array[]=fourth value
Attempts to turn the given INI string into a nested data object.
// You can also use `decode` const object = parse(`<INI Text>`)
Encodes the given data object as an INI formatted string.
// You can also use `encode`
stringify(object,{
/**
* Whether to insert spaces before & after `=`
*
* Disabled by default to have better
* compatibility with old picky parsers.
*/
whitespace : false ,
/**
* Whether to align the `=` character for each section.
* -> Also enables the `whitespace` option
*/
align : false ,
/**
* Identifier to use for global items
* and to prepend to all other sections.
*/
section ,
/**
* Whether to sort all sections & their keys alphabetically.
*/
sort : false ,
/**
* Whether to insert a newline after each section header.
*
* The TOSHIBA & FlashAir parser require this format.
*/
newline : false ,
/**
* Which platforms line-endings should be used.
*
* win32 -> CR+LF
* other -> LF
*
* Default is the current platform
*/
platform ,
/**
* Whether to append `[]` to array keys.
*
* Some parsers treat duplicate names by themselves as arrays
*/
bracketedArray : true
})
For backwards compatibility any string passed as the
options parameter is treated as the section option.
stringify(object,'section')
Turn the given string into a safe to
use key or value in your INI file.
safe(`"unsafe string"`) // -> \"unsafe string\"
Or reverse the process with:
unsafe(`\\"safe string\\"`) // -> "safe string"
