How to get VS Code Debug to work with Foreman and nf start

微笑、不失礼 提交于 2020-05-17 06:05:38
问题 I am using this base Heroku project for a Node cluster environment. https://github.com/heroku-examples/node-workers-example However since it uses foreman to create multiple processes on start, I can't figure out how to connect it to VS Code Debug using a launch.json file like I normally would. This is the start command. "scripts": { "start": "nf start", } 回答1: It took me a little while to figure out a workable debugging methodology.. but to debug the server, this is what I am currently using:

Is there a comment character for foreman's .env file?

混江龙づ霸主 提交于 2020-05-12 11:07:10
问题 Can you comment out lines in a .env file read by foreman? 回答1: FWIW, '#' appears to work as a comment character. It at least has the effect of removing unwanted environment declarations. It might be declaring others starting with a #, but... it still works. EG DATABASE_URL=postgres://mgregory:@localhost/mgregory #DATABASE_URL=mysql://root:secret@localhost:3306/cm_central results in postgres being used by django when started by foreman with this .env file, which is what I wanted. 回答2: I THINK
