remark-lint rule to warn when the spacing between a list item’s bullet and its content violates a given style
The remark-lint-list-item-indent package is a plugin for remark-lint that ensures consistent indentation for list items in Markdown files. It helps maintain a uniform style and prevents issues related to inconsistent list item indentation.
Check for consistent indentation
This feature checks that list items are indented using spaces. The configuration specifies 'space' to enforce this rule.
module.exports = {
plugins: [
['remark-lint-list-item-indent', 'space']
]
};Check for tab indentation
This feature checks that list items are indented using tabs. The configuration specifies 'tab' to enforce this rule.
module.exports = {
plugins: [
['remark-lint-list-item-indent', 'tab']
]
};remark-lint is a general-purpose Markdown linter that can be extended with various plugins, including remark-lint-list-item-indent. It provides a wide range of rules for ensuring Markdown quality and consistency.
markdownlint is a Node.js style checker and lint tool for Markdown files. It offers a comprehensive set of rules and can be customized to enforce specific styles, similar to remark-lint-list-item-indent.
markdown-it is a Markdown parser that can be extended with plugins to enforce specific styles and rules. While it is primarily a parser, it can be used in conjunction with linting tools to achieve similar functionality to remark-lint-list-item-indent.

First some background.
The number of spaces that occur after list markers (*, -, and + for
unordered lists and . and ) for unordered lists) and before the content
on the first line,
defines how much indentation can be used for further lines.
At least one space is required and up to 4 spaces are allowed.
If there is no further content after the marker then it’s a blank line which
is handled as if there was one space.
If there are 5 or more spaces and then content then it’s also seen as one
space and the rest is seen as indented code.
Regardless of ordered and unordered,
there are two kinds of lists in markdown,
tight and loose.
Lists are tight by default but if there is a blank line between two list
items or between two blocks inside an item,
that turns the whole list into a loose list.
When turning markdown into HTML,
paragraphs in tight lists are not wrapped in <p> tags.
How indentation of lists works in markdown has historically been a mess,
especially with how they interact with indented code.
CommonMark made that a lot better,
but there remain (documented but complex) edge cases and some behavior
intuitive.
Due to this, 'tab' works the best in most markdown parsers and in
CommonMark.
Currently the situation between markdown parsers is better,
so the default 'one',
which seems to be the most common style used by authors,
is okay.
remark-stringify uses listItemIndent: 'one'
by default.
listItemIndent: 'mixed' or listItemIndent: 'tab' is also supported.
