Does clinic.js works with Nextjs?
See original GitHub issueExpected Behavior
I have a project that is in Nextjs and Typescript. As we really need SEO, SSR is a must. However the project seems to be really slow and we are trying to dig in what is the root causes of the issue and I just found out about Clinic.js which seems to be a good tool for this.
When running the command: $ clinic doctor -- node dist/server/index.js
I would expected to get the report from Clinicjs.
Current Behavior
Running the command: $ clinic doctor -- node dist/server/index.js
ends with this result always:
