I am trying to implement custom audits using the lighthouse library lighthouse and executing some Javascript commands within the Gatherer I get the following error:
...ANSWER
Answered 2022-Apr-04 at 07:27There is already an artifact that collects all font information on a page: https://github.com/GoogleChrome/lighthouse/blob/master/types/artifacts.d.ts#L139
As for the actual error, you'd need to write a more complex function that you'd pass to evaluate to process the DOM and return only the data you want. If you write anything more than a single-line expression I suggest using driver.evaluate instead (see the Lighthouse repo for examples).

I have set all my meta description individually depending the page.

Answered 2022-Mar-22 at 14:38You need to generate a meta tag like . Your code would not do that. The example code you linked to shows that both the hid and the name should be "description" (literally.) You appear to be putting the page title into the name attribute of the tag, which is not correct. Correct code should be more like:

QUESTION
My Company Hired someone outside on up upwork for cheap to optimize for lighthouse score. He asked me to review what they did and I'm trying to figure out exactly what they did. Our scores definitely went up but it looks like a special set of rules for lighthouse-chrome and GTMetrix agents that ignore certain things in order to get a better score.
Can anyone decipher this and tell me if this is just a hack or legit?
...ANSWER
Answered 2022-Mar-02 at 05:39This appears to be a scam.
Searching for that code, I can find similar code here and here.
The code is intentionally difficult to read, but the idea appears to be that when it detects that page speed is being measured (seemingly by checking the User-Agent string), it loads an empty page; which will obviously be faster. I'm not sure what it's doing with script and link tags, so this variant might be a little different, but that's what they're reporting on Shopify.
I would be extremely suspicious based on that first line alone though. Any time you have strings with information that's encoded oddly embedded in the string, there's the potential that it's being used to hide information. Here, they appear to be trying to hide the fact that they're checking the user-agent string for 'Chrome-Lighthouse' ('\x43\x68\x72\x6F\x6D\x65\x2D\x4C\x69\x67\x68\x74\x68\x6F\x75\x73\x65'), but it could have also been code that stole session cookies, or replaced links on pages to point to malicious sites. Be very cautious of code that appears to be evading human or other static detection.

I wanted to make a lighthouse test using cypress-audit, but after doing everything they said on https://www.npmjs.com/package/cypress-audit it doesn't work. I can use "cy.lighthouse()" in the cypress/support/commands.js, but not in files with extension like .spec.ts or .ts ( i get "Property 'lighthouse' does not exist on type 'cy & EventEmitter'.ts(2339)" error ). I already tried to find any solutions on the internet, but nothing worked.

Answered 2022-Jan-26 at 11:12There are some type defs in the cypress-audit package that should be kicking in. Perhaps it's the mixture of ts and js files?
Try adding these to /cypress/support/index.ts
