This is a simple fork of DataFrame-JS that allows using dataframes without NPM!
In any modern browser or inside Deno, just run the following:
const { DataFrame } = (await import('https://cdn.skypack.dev/@!!!!!/polarbear@1.0.2')).default
const rowsOfData = [ [1,2,3,3], [4,5,6,7] ]
const columnNames = ['a','b','c','d']
const df = new DataFrame(rowsOfData, columnNames)
Official Documentation: https://gmousse.gitbooks.io/dataframe-js/

DataFrame-js provides an immutable data structure for javascript and datascience, the DataFrame, which allows to work on rows and columns with a sql and functional programming inspired api.
With the DataFrame, you can easily do a ton of complex stuff such as join, groupby, exploration tasks, machine learning...
It's mainly designed to work on server-side (with node) but it also works in the browser (without file system related features).
Example:
import DataFrame from "dataframe-js";
import { data, columns } from "./titanic_data.js";
const df = new DataFrame(data, columns);
const filteredDf = df
.filter(row => row.get("survived") === "yes")
.select("class", "age", "sex");
filteredDf.show(3);| class | age | sex |
----------------------------------------
| 1st class | adults | man |
| 1st class | adults | man |
| 1st class | adults | woman |
via git: npm install git+https://github.com/Gmousse/dataframe-js.git
via npm: npm install dataframe-js
via yarn: yarn add dataframe-js
For the browser, we have change the script provider (rawgit) because it will close soon, consider to update the url!!!
in the browser (1.4.0):
- for production
<script src="https://gmousse.github.io/dataframe-js/dist/dataframe.min.js"></script>(~ 80ko) - for development
<script src="https://gmousse.github.io/dataframe-js/dist/dataframe.js"></script>(~ 300ko)
