Minimal CLI converter from newline-delimited JSON to a JSON array

Features:

• converts NDJSON to JSON
• uses streams to be able to handle very large files with minimal memory use
• zero validation: you have the responsability to send some proper newline-delimited JSON on ndjson-2-json stdin

npm i -g ndjson-2-json

# Convert all a file
cat some.ndjson | ndjson-2-json > some.json
# which can also be written
ndjson-2-json < some.ndjson > some.json

# Convert just the 20 first lines
head -n 20 some.ndjson | ndjson-2-json > 20_first_entries.json
