Expected output
Change log says that fromString is deprecated, so trying to use htmlToText. Not sure why htmlToText is not recognized as a function in my code. Tried wrapping it in another function, in an IFFE, nothing works except using the fromString function.

Version information

• html-to-text: 6.0.0
• node: 12.16.2

---

I'm trying to use htmlToText inside of a curried function (using ramda curryN) and get "TypeError: htmlToText is not a function". It DOES work if instead I use "fromString".
example of failing code:
var objectFromEMail = R.curryN(3, (splitCharsExp, matchCharsExp, payload) => { let rawText = payload.text ? payload.text : payload.html ? htmlToText(payload.html) : Error - failed to parse email body (no text or html)! ...
example of successful code:
var objectFromEMail = R.curryN(3, (splitCharsExp, matchCharsExp, payload) => { let rawText = payload.text ? payload.text : payload.html ? fromString(payload.html) : Error - failed to parse email body (no text or html)! ...

Pay attention to how the import is done.
There is no default export.

const { htmlToText } = require('html-to-text');

I should've made it more clear in the changelog.

Found the problem; I hadn't imported with a specific version so I was using 5.1.1. Already had it in my node_modules and it's required by mailparser 2.7.7. Upgrading html-to-text to 6.0.0 solves the problem.

Excerpt from README:

• fromString method - use convert or htmlToText instead;
• positional arguments in BlockTextBuilder methods - pass option objects instead.

Selectors

Some example:

const { convert } = require('html-to-text');

const html = '<a href="/page.html">Page</a><a href="!#" class="button">Action</a>';
const text = convert(html, {
  selectors: [
    { selector: 'a', options: { baseUrl: 'https://example.com' } },
    { selector: 'a.button', format: 'skip' }
  ]
});
console.log(text); // Page [https://example.com/page.html]

I have the same problem...

@mithunmunsi if your message above from last week is accurate - then it is not the same problem.

If you're using fromString with version 9 or newer - you cannot read documentation.

If you have an error convert is not defined - it is a different problem. Still likely a user error.
It seems most often occurring to users not able to do through research before writing here. Your message is not exception - it tells me nothing and just shows you're not able to understand what you're doing.
And those who do a thorough research - are likely to resolve it by themselves.
So, I'm inclined to believe it is still a user error.

The only case of reporting the issue then finding the cause is available above.
It involves a misalignment between what version you think you're using and what version is actually used.

const htmlToText = require('html-to-text');
const mailOptions = {
from: this.from,
to: this.to,
subject,
html,
text: htmlToText.fromString(html)
};

@mithunmunsi Try this:

const { convert }= require('html-to-text');
const mailOptions = {
from: this.from,
to: this.to,
subject,
html,
text: convert(html)
};
