Is there anything specific I need to add so it doesn't exclude the constant? For this we need to use its functions to calculate a clustered but unadjusted VCOV by setting type = "HC0" and cadjust = FALSE. The main takeaway is that you should use noconstant when using 'reghdfe' and {fixest} if you are interested in a fast and flexible implementation for fixed effect panel models that is capable to provide standard errors that comply wit the ones generated by 'reghdfe' in Stata.
