Failed to parse source map from ...

pascal-mueller commented 1 year ago

Issue Description

I'm trying to add react-native-gifted-chat to my expo application. I added the example component given in the README. I get a lot of the following warnings.

WARNING in ./node_modules/react-native-gifted-chat/lib/logging.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from '/home/.../node_modules/react-native-gifted-chat/src/logging.ts' file: Error: ENOENT: no such file or directory, open '/home/pascal/projects/spark/spark-ui/node_modules/react-native-gifted-chat/src/logging.ts'

Now I observed the following:

`cat /home/.../node_modules/react-native-gifted-chat/src/logging.ts`

which gives `No such file or directory`, that's because there is no `src` dir in `node_modules/react-native-gifted-chat/` but there is `lib`. So the Error makes sense.

My question is: Why are those files missing?

#### Steps to Reproduce / Code Snippets

Here's my package.json

{
  "name": "myapp",

  "main": "node_modules/expo/AppEntry.js",

HI, I am running into the same or similar issue. where you able to resolve?

I didn't had time to look into it yet. Since the source maps are only used for debugging i.e. during development, it isn't critical for a functional application. You can basically ignore them since in production mode they shouldn't show up at all.

I used the env variable GENERATE_SOURCEMAP=false to get rid of the warnings since the files are simply not generated. You can add it to the scripts key in the package.json e.g. like this

    "scripts": {
        "start": "GENERATE_SOURCEMAP=false && expo start",
        "android": "expo start --android",
        "ios": "expo start --ios",
        "web": "expo start --web"
    },

but it doesn't do much since it doesn't work for hot reload. If I find the time to look into it in detail and I find the actual issue, I'd post here.
