How to add new user agents ?

[pashkasan]

I would like to add the latest chrome user agents v91, v92, v93 and chrome based browsers like Yandex, Opera. But on first look seems like it very complicated, is there any instructions on this?

Regarding Chromes: I'm going to integrate the latest chrome browser data in the near future. Just need to get to it.

For Other browsers or in interim:

Building a perfect emulator of those agents is going to be complicated, but you could "fork" the default-browser-emulator to do what you're talking about. There's some documentation, but you're likely going to have to look at the code.

Depending on if you want to run headless, you might also need to generate data to "polyfill" the headless versions of those browsers to look headed. With Chrome, the process is:

1. Generate chrome browsers that don't auto-update (https://github.com/ulixee/hero/actions)
2. Integrate into a BrowserEmulator that correctly launches each when a userAgentString is provided that requests them (see

   secret-agent/plugins/default-browser-emulator/index.ts

   Line 134 in 424c445

   )
3. Test that our Chrome devtools flow works with Yandex and Opera
4. Optionally (best result): Analyze the the tls/headers/dom to determine anything that needs to be modified by your emulator at runtime (Test suites here: https://github.com/ulixee/double-agent/). You could use something like BrowserStack to generate your data.
