JavaScript/TypeScript bindings for sciformats, a library for reading scientific data formats.
npm install sciformats_jsJavaScript/TypeScript bindings for sciformats, a library for reading scientific data formats.
This library allows reading multiple scientific data formats. Currently, the following formats are supported:
- AnDI/AIA for Chromatographic Data (ASTM E1947-98(2022), ASTM E1948-98(2022))
- AnDI/AIA for Mass Spectrometric Data (ASTM E2077-00(2016), ASTM E2078-00(2016))
- Generalized Analytical Markup Language (GAML)
- JCAMP-DX (JCAMP-DX)
Import "sciformats_js" for use with webpack (for use with Vite see vite-plugin-wasm) and "sciformats_nodejs" for use with Node.js.
``js
// Initialize scanner repository with all supported data types.
const scannerRepository = new ScannerRepository();
// In a browser, read file from an element of type "file".
const file = input.files[0];
const fileName = file.name;
// Read file content.
const buffer = await file.arrayBuffer();
// As a Uint8Array is expected, an ArrayBuffer cannot be used directly.
const uint8Array = new Uint8Array(buffer);
// For Node.js you can read a file into a Uint8Array natively.
// const uint8Array = readFileSync(path);
// Ensure that the file has a supported format.
const isRecognized = scannerRepository.isRecognized(fileName, uint8Array);
if (!isRecognized) {
return;
}
// Get a reader through which data from the file is retrieved.
const reader = scannerRepository.getReader(fileName, uint8Array);
// Read the root node.
const rootNode = reader.read('/');
// Use node content.
const name = rootNode.name;
const parameters = rootNode.parameters;
const data = rootNode.data;
const metadata = rootNode.metadata;
const table = rootNode.table;
const childNodeNames = rootNode.childNodeNames;
// Read the fourth child node. Indexing starts at 0. There are as many child nodes as elements in the childNodeNames list.
let child3Node = reader.read('/3');
// Read the first nested child node of the fourth root child node.
let child30Node = reader.read('/3/0');
