parse5.parseFragment is not a function => parsers/parse5.js|ts

[MathiasBoisgardDev]

Hello !

I found an issue after searching for a while where it came from.

I use enzyme in a project for my Unit Tests, and the library uses cheerio for its internal function 'render'

The problem

When I execute my tests, every call to 'render' method from enzyme has an error :

TypeError: parse5.parseFragment is not a function

This error only occurs for cheerio version >v1.0.0-rc.5 as the structure of your library changed between .5 and .6
Before the import of parse5 was made directly in lib/parse.js and then moved to parsers/parse5.js

The problem is that when you require('parse5') in parsers/parse5.js, you actually require the file itself, so

var parse5 = require('parse5');
is actually an object containing the function parse and render and not the functions from the library parse5 (parse, parseFragment and serialize)

The solution

I can do a Pull request to change the name of the file and so avoid this problem (tested locally and functionnal)

Hi @MathiasBoisgardDev, thanks for the report! Could you provide some details on which environment you are using? Module resolution as it is done within Node shouldn't have an issue here.

[MathiasBoisgardDev]

Yeah sure:

MacOS Big Sur : v11.3.1
node : v12.14.1

Do you need more than those information ?

Just wanted to note that I have the same exact issue with this library. I have to lock it down to rc5 to get around it. I'm on latest Windows, latest stable node.js.

[MathiasBoisgardDev]

Same, everything works fine by locking on .5
Would be great to be able to be up to date though
