Making data processing safe and delightful with TypeScript
Say hello to the simple lightweight library for type-safe data processing written in TypeScript, optimized for Bun, providing amazing DX and reducing runtime errors.
Overview
import Breadroll from "breadroll";
const csv = new Breadroll({ header: true });
const df = await csv.open.local<T>("./test/data/cities.csv", ",");
const selected = df.select(["name", "country_code", "country_name", "latitude", "longitude"]);
console.table(selected.value);In this example, the Breadroll instance accepts its options object DataframeReadOptions, we now move on to open a
file from disk using .open.local(...), then select a few columns from the dataframe, retrieve the value and then
print out the value using console.table(...). The resulting output to the console, will be also follows;
| | name | country_code | country_name | latitude | longitude |
| --- | --------- | ------------ | ------------ | -------- | --------- |
| 0 | AshkÄsham | AF | Afghanistan | 36.68333 | 71.53333 |
| 1 | Fayzabad | AF | Afghanistan | 37.11664 | 70.58002 |
| 2 | Jurm | AF | Afghanistan | 36.86477 | 70.83421 |
| 3 | Khandūd | AF | Afghanistan | 36.95127 | 72.318 |
| 4 | RÄghistÄn | AF | Afghanistan | 37.66079 | 70.67346 |
