How to force color in CLI output?

[gajus]

I am piping output to @roarr/cli so that we could format the logs that the tests produce. However, piping logs to another service forces vitest to strip ANSI color codes from its own output.

I know there is --no-color option. However, how do I force vitest to produce color output?

Does FORCE_COLOR=1 environment variable work for you? E.g:

$ FORCE_COLOR=1 pnpm test | less

> [email protected] test /x/vitest-example-project
> vitest run


ESC[7mESC[1mESC[36m RUN ESC[39mESC[22mESC[27m ESC[36mv0.31.0ESC[39m ESC[90m/x/vitest-example-projectESC[39m
....

This only works for me if !process.env.CI
