Answer 1

Based on the number of rules you want to ignore (All, or Some), and the scope of disabling it (Line(s), File(s), Everywhere), we have 2 × 3 = 6 cases.

---

1) Disabling "All rules"

---

Case 1.1: You want to disable "All Rules" for "One or more Lines"

Two ways you can do this:

1. Put /* eslint-disable-line */ at the end of the line(s),
2. or /* eslint-disable-next-line */ right before the line.

---

Case 1.2: You want to disable "All Rules" for "One File"

• Put the comment of /* eslint-disable */ at the top of the file.

---

Case 1.3: You want to disable "All rules" for "Some Files"

There are 3 ways you can do this:

1. You can go with 1.2 and add /* eslint-disable */ on top of the files, one by one.
2. You can put the file name(s) in .eslintignore. This works well especially if you have a path that you want to be ignored. (e.g. apidoc/**)
3. Alternatively, if you don't want to have a separate .eslintignore file, you can add "eslintIgnore": ["file1.js", "file2.js"] in package.json as instructed here.

2) Disabling "Some Rules"

---

Case 2.1: You want to disable "Some Rules" for "One or more Lines"

Two ways you can do this:

1. You can put /* eslint-disable-line quotes */ (replace quotes with your rules) at the end of the line(s),

2. or /* eslint-disable-next-line no-alert, quotes, semi */ before the line.

---

Case 2.2: You want to disable "Some Rules" for "One File"

• Put the /* eslint-disable no-use-before-define */ comment at the top of the file.

Case 2.3: You want to disable "Some Rules" for "Some files"

• This is less straight-forward. You should put them in "excludedFiles" object of "overrides" section of your .eslintrc as instructed here.
