@svgr/cli generated exports incomplete / truncated

[m7kvqbe1]

🐛 Bug Report

The generated index.tsx exports file from the below command appears to be either incomplete or truncated. I get a different set of exports written to file each time I run the command. It looks like there is some kind of race condition going on.

To Reproduce

Steps to reproduce the behavior:

1. Create multiple directories of SVG icons.

2. Run the following:

rm -rf src/icons; svgr --ext tsx -d src/icons src/assets/**/

3. Note the generated exports in src/icons/index.tsx

Expected behavior

Exports for all of the generated React components are included within the index.tsx file.

It's worth noting that i'm currently working around this issue using a little bit of my own Bash:

#!/usr/bin/env bash

set -uo pipefail
trap 's=$?; echo "$0: Error on line "$LINENO": $BASH_COMMAND"; exit $s' ERR
IFS=$'\n\t'

:> src/index.ts

for file in src/icons/*; do
  filename=$(basename -- "$file")
  filename_no_ext=${filename%%.*}
  echo "export {default as Icon${filename_no_ext}} from './icons/${filename_no_ext}'" >> src/index.ts
done

Hello @m7kvqbe1, thanks for this bug. I think the issue only occurs with --ignore-existing option. Work in progress!
