There are quite a few small libraries, so let's group them by a common purpose.

🎯 11 Range Libraries

Range means an array of two text character index numbers, "from" and "to" (plus optional third element, string, which marks "what to add").

For example, "from the third character to the fourth character" could be marked with array [3, 4].

There can be a third element in a range array, what to add instead of the range. For example, [10, 12, "add this"]. When there is no third element in the range array, like [10, 12], that would mean "delete from index 10 to index 12". Empty third element is the same as if it was missing.

For example, a range [1, 3] in a string "abcdef" would mean bc because "b" is at index number 1 (counting starts at zero) and 3rd is "d". The beginning of the range is inclusive, and the ending is not. Hence, the result "bc".

Another example, if you want to replace "{placeholder}" with "John" in a string "Hi {placeholder}!"^, the range would be [3, 16, "John"].

Now, if you have many ranges, you put them into an array. You get an array of ranges. Majority of range- libraries process such arrays of ranges: sort bunch of ranges, fix overlapping ranges and so on.

Practically, we need ranges when we process strings and want to "keep a note" of what needs to be deleted or replaced later. The idea is, instead of processing the string many times:

"find out what needs to be done with a string" ->
"mutate the string" ->
"find out what more needs to be done with a string" ->
"mutate the mutated string" ->
... and so on,

We only "compile a to-do list" — push the ranges into an array. When we finish gathering them, we do all the actions in one go.

Performing string processing only once is better for both performance reasons (fewer actions = faster) and for consistency (in-between taking the notes, we operate on the original string instead of its previously mutated version).

If you think, strings are immutable in JavaScript — each change of a string means rewriting it in a computer memory. Let's say you want to add a letter and delete the same letter in a string which consists of a thousand characters. Both actions cancel each other out. However, if you do the string edits sequentially, you write a thousand characters to memory two times, after every amend. On the other hand, if you use ranges approach, you'd only create a new record in the computer memory, housing a couple of arrays, each consisting of couple index numbers. When you process the ranges, they would cancel each other out, and we would not write anything to the memory at all. Now, if you scale this — longer strings, more amends, and done many times — you'll soon feel the difference in performance.

🔮 20 Object Processing Libraries

When we say "object" we mean a plain object in JavaScript, for example, { name: "Bob" }. Usually, plain objects come from JSON files, and often they are deeply nested. The following libraries help us to traverse them, set and delete keys and compare objects.

"ast-" in the library's name below just emphasises that it really works on nested objects (so-called Abstract Syntax Trees that come from parsed things).

🤝 Contributing

  • If you see an error, raise an issue.
  • If you want a new feature but can't code it up yourself, also raise an issue. Let's discuss it.
  • If you tried to use a package, but something didn't work out, also raise an issue. We'll try to help.
  • If you want to contribute some code, fork the monorepo via GitLab, then write code, then file a pull request on GitLab. We'll merge it in and release.

In monorepo, npm libraries are located in packages/ folder. Inside, the source code is located either in src/ folder (normal npm library) or in the root, cli.js (if it's a command line application).

The npm script within each package's package.json "dev", the "dev": "rollup -c --dev --silent" builds the development version retaining all console.logs with row numbers. It's handy to have js-row-num-cli installed globally so you can automatically update the row numbers on all console.logs.
