Detergent is a tool to prepare a text for pasting into HTML.
The main idea is, we need a program which, on default settings and with the least effort will make any text safe and optimal for pasting into HTML.
Text on web pages and email templates should look at its best:
- text should be HTML-encoded
- text should have no invisible characters
- text should use smart curly quotes and n/m-dashes where applicable
These requirements are quite universal, and default settings of Detergent.io are aiming precisely at them.
Alternatively, Detergent can be used to strip HTML and prepare a text for non-HTML uses, for example, pasting into PSD or Sketch design files.
Conceptually, this web page, detergent.io, is separate from its API, an Open Source npm package
detergent (npm page / monorepo).
Detergent-the-npm-package is separate from Detergent.io (this website) to allow other people to use Detergent in their programs, websites, Gulp tasks and everywhere else.
For the same reasons, all the major functions in the API are also separated into separate npm packages:
html-entities-not-email-friendly(npm page / monorepo) — a list of all named HTML entities which are not email-friendly — we use it when encoding, to know when to switch to numeric HTML entities
string-apostrophes(npm page / monorepo) — typographically-corrects all kinds of apostrophes to left/right single quotes or primes.
string-collapse-white-space(npm page / monorepo) — does what it says on the tin — collapses whitespace in a string: " aaa bbbb " → "aaa bbbb", also trims the input and crunches the line breaks
string-fix-broken-named-entities(npm page / monorepo) — fixes broken named HTML entities, for example,
&nbs;, a non-breaking space with missing "p" is clearly an error and no similar entities exist, it is an
and needs to be fixed
string-remove-widows(npm page / monorepo) — widow word removal
string-strip-html(npm page / monorepo) — non-parsing HTML tag processor which detects HTML tags in mixed source code (anything, including ESP code, templating languages, programming languages, you name it) — tag recognition, stripping and skipping features are based on this program
there are few more, but above are the main ones.
The main features of detergent.js, our API:
- Encodes all characters outside ASCII using named HTML entities if they are supported across email clients, falls back to numeric otherwise
- Removes all invisible characters like ETX
- Improves English style: converts dashes to n/m dashes, apostrophes to curly quotes and so on — two English Grammar books have been coded up
- Prevents widow words
- API reports all settings that are not applicable for the current input — UI greys them out to save you from mental fatigue
- Recognises HTML, let's you granularly strip or skip arbitrary tags
The main features of this web app
- Instant result, calculated on a web worker
- Always the latest API is consumed straight from NPM via unpkg —this web app is never out of date
- Dark and light modes without ever flashing the opposite colour
- Preferences saved in browser's local storage
- No cookies of any kind
- No advertising, sales or sneaky lead-gen
There are no programs on the market comparable to Detergent.
he.js package is used by Detergent — it's driving the Detergent's HTML-encoding.
Email On Acid Character Converter is way inferior to
he.js — to start with, it will neither remove invisible characters from text nor encode them. It's UI sucks, and it's ridden with marketing lead-gen.
Typograf (app/package) seems at first glance like a comparable app, but it's aimed at text preparation for web pages in the Russian language. Typograf's UI has English switch, but it has just a basic set of rules for n/m dashes and apostrophes. Typograf can't be used as an encoding tool either —
£ is not even encoded, for example. Typograf's UI could be improved speaking mildly; it's got 97 settings with no filtration what is applicable for a given input, all hidden in the sidebar and not quite user-friendly.
