If you created Vue project via
vue create my_proj and had eslint enabled in the options, You should get a .eslintrc.js in the root folder. Sometimes, I have seen it isn’t created. Worry not, here is how you can generate it manually.
Make sure you have eslint module in node_modules folder.
Then in console, do this: (from your project root directory):
that’s it. You will have to walk through a bunch of options, and then .eslintrc.* (.js , .json or whatever format you chose in options) will be there in your project root.
