Correct PostScript Name Resolution

[aamirsdev]

Photoshop requires precise PostScript names (e.g., "ArialMT" instead of "Arial") to correctly map font family, weight, and style properties. Existing font libraries or methods I have tried either return incomplete or incorrect PostScript names that do not match Photoshop’s expectations. I need a reliable way or library that can determine the exact PostScript name Photoshop requires based on font family, weight, and style.
What I tried:
Used the font-list Node.js library to retrieve font metadata, including PostScript names.
Attempted this lookup:

expects.const { getFonts2 } = require('font-list');
async function getPostScriptName(family, fontWeight, fontStyle) {
    const normalizedFamily = family.trim().toLowerCase();
    const canvasFontStyle = fontStyle.toLowerCase();
    const normalizedWeight = fontWeight.toLowerCase();
    const fonts = await getFonts2();
    const foundFont = fonts.find(font =>
        font.familyName.toLowerCase().includes(normalizedFamily) &&
        font.weight.toLowerCase() === normalizedWeight &&
        font.style.toLowerCase() === canvasFontStyle
    );
    return foundFont?.postScriptName;
}

However, this returns generic PostScript names like "Arial" rather than the Photoshop-required "ArialMT", causing font mapping issues.
Manual mapping functions are error-prone and hard to maintain at scale.

I don't know any way other than just setting up text layers in photoshop and then extracting names from the saved PSD file. I think translating names of fonts using font files is out of scope for this library.

Thanks for your response!
Yes correct determining the correct PostScript name is outside the scope of this library, but I wanted to share some observations and ask for guidance.
I created a few test text layers in Photoshop using different font families and font styles, then analyzed the resulting PSD files. What I found is that Photoshop seems to generate the PostScript name based on a pattern that combines the font family and style — something like:
(FontFamilyName-FontStyleName)

For example:
For font family Amandine with style Bold, Photoshop created this PostScript name:
"PostScriptName-Amandine-Bold"

However, for some fontfamily, it adds additional suffixes like MT or PS-MT. For instance:
Font family TimesNewRoman, style Italic resulted in:
"PostScriptName-TimesNewRomanPS-ItalicMT"

So while many fontfamily follow a consistent pattern, some include these extra identifiers.
Could you please guide me on whether there’s a reliable or standardized approach (or maybe a library or reference) to determine the exact PostScript name that Photoshop expects based on the font family and style?

I don't know anything about naming of font files, sorry.
