parcel-transformer-dsv

DSV transformer for Parcel 2 using d3-dsv.

Usage

1. Install by running yarn add --dev michigandaily/parcel-transformer-dsv.

2. In your Parcel config (i.e. .parcelrc), add this transformer like the following:

   {
    "extends": "@parcel/config-default",
    "transformers": {
      "*.{csv,tsv,dsv}": [
        "@michigandaily/parcel-transformer-dsv"
      ]
    }
   }

Now, you can import a CSV file like so:

import data from "../data.csv"

You can also import a TSV file:

import data from "../data.tsv"

If you have a file with a different type of delimiter, you can import it with a delimiter query parameter. Consider a file with values delimited with colons. You can import it like so:

import data from "../data.dsv?delimiter=:"

By default, this transformer will use d3.autoType to infer data types. If you want to disable automatic typing, import with a autoType=false query parameter:

import data from "../data.csv?autoType=false"

If you want to only retrieve certain columns of values from a DSV, use the columns query paramter. The following import will only import the a and b columns from a CSV file:

import data from "../data.csv?columns=a,b"
