parcel-plugin-asset-csv v0.1.5

parcel-plugin-asset-csv

A parcel plugin for adding CSVs as a supported asset type

Usage

Add the plugin to your project as a dependency:

npm install parcel-plugin-asset-csv --save

Then you can require CSVs in any asset type that outputs to JavaScript. (e.g, .js or .ts):

example.csv

first name, last name, age
john, doe, 21

const exampleCSV = require('./example.csv');

console.log(example.csv);
// => [['first name', 'last name', 'age', ['john', 'doe', '21']]

console.log(example.csv[0][0]);
// => 'first name'

console.log(example.csv[1][0]);
// => 'john'

Configuring

The papaparse library used to parse CSV assets can be configured by placing a .papaparserc or .papaparse.js file in the root of your project. These must be a valid papaparse config.

For example, in .papaparse.js:

module.exports = {
    delimiter: ",",
    quoteChar: "'",
    header: true, // Set to false to disable turning each row into an object with header keys
    transformHeader: (header) => header.toLowerCase() // Transform all header keys into lowercase
    dynamicTyping: true, // Set to false to disable converting columns into their true types (e.g, string to number)
    fastMode: false, // Set to true to speed up processing, as long as there are no `quoteChars` in your assets
    transform: (val, columnNumber) => val.toLowerCase() // Transforms each value, in this case making all values lowercase
}
