Example usage

make a new folder and turn it into a dat store

mkdir foo
cd foo
dat init

put a JSON object into dat

echo '{"hello": "world"}' | dat --json

stream a CSV into dat

cat some_csv.csv | dat import --csv
custom delimiter, --delimiter works too
cat some_csv.csv | dat import --csv -d $'\r\n'

specify a primary key to use

echo $'a,b,c\n1,2,3' | dat import --csv --primary=a
echo $'{"foo":"bar"}' | dat import --json --primary=foo

stream the most recent of all rows

dat cat

view raw data in the store

dat dump

start a dat server

dat serve

then you can poke around at the REST API:

/_changes
/_changes?include_data=true
/_package
/:docid
POST /_bulk content-type: application/json (newline separated json)

pull data from another dat

dat pull http://localhost:6461

push data to another dat

dat push http://localhost:6461

grab all the NPM registry metadata

dat clone http://dat-npm.mathiasbuus.eu

delete the dat folder (removes all data + history)

rm -rf .dat

dat import

you can pipe line separated JSON data into dat on stdin and it will be stored

cat foo.line-separated-json-objects | dat import --json
