Your idea is fine. First find the offsets in the original code where each line starts. Then compare the start index of the node with those collected indexes to determine the line number.

I will assume here that you want the reported line number to refer to the original code, not the code as it is returned by your function.

So from bottom up, make the following changes. First expect the line number as argument to addBeforeCode:

Node modules disappear after initializing the localy installed ESLint

Asked 2018-Mar-22 at 20:27

In my initial react application (created by react-native init project_name). In my project folder, I install my ESLint locally by yarn add eslint --dev. Then I initialize my configuration by ./node_modules/.bin/eslint --init (with Airbnb style guide, using React, and JSON configuration file format). The installed eslint is disappeared in ./node_modules/.bin folder.

ANSWER

Answered 2018-Mar-22 at 20:27

This is caused by a bug in NPM 5 where npm install will delete almost all of your dependencies. This was the relevant issue. Even though you are using yarn, eslint will use npm under the hood to install the dependencies it needs, and thus will run into the aforementioned bug.

This has very recently been fixed in npm >= 5.7.1, so you will need to upgrade npm and then reinstall all of your modules.

Personally, I'd just recreate the entire project from scratch since it doesn't seem like you've done anything yet. It would be a lot more straightforward than trying to fix things.

By upgrading, you will also be able to use react-native-cli without error as prior to v5.7.1, you were actually supposed to use NPM 4. See this bug.
