For a full list of differences between Node.js version 10 and Node.js version 14 see. While there are no changes to the current set of Domains and Competencies for the JSNSAD and JSNAD Exams, candidates are advised to review functionality of libraries or frameworks on Node.js version 14. This allows for frameworks with their own initialization CLIs to be used more easily than before, for example see. The JSNSD exam has also been updated to become more web-framework friendly, the npm start field is now the essential entry-point for determining how a web server is started. Industry standards and best practices will be tracked over the next year and EcmaScript modules may become the default in future updates.

This opt-in approach for EcmaScript modules is in keeping with Node’s module determination algorithm, see. In either of those cases a module would be loaded like so: import fs from 'fs'Ĭandidates may also explicitly opt-in to CommonJS by setting the type field to commonjs or by renaming the answer.js to answer.cjs but this is unnecessary as the absence of a type field means the answer.js file is interpreted as CommonJS anyway. To opt-in to native EcmaScript modules, candidates may either set the type field of the package.json file to module or may rename the answer.js file to answer.mjs. So loading a module would be achieved like so: const fs = require('fs') By default, the answer.js file is therefore considered a CommonJS module. The package.json file does not contain a type field, as is the case when generating a package.json file with npm init. The updated exam will include the ability to use either native EcmaScript modules or CommonJS modules to answer questions, with CommonJS remaining the default and EcmaScript modules as an opt-in.įor example a given task on the examination may provide a folder containing an answer.js file and a package.json file. All tests taking place after 8:00 pm PT on Jwill be based on Node.js version 14. Changes will come into effect November 3, 2020. The OpenJS Node.js Application Developer (JSNAD) and the OpenJS Node.js Services Developer (JSNSD) Exams (Node.js Certifications) will be updated from Node.js version 10, which is now in maintenance, to Node.js version 14, which is the most current LTS (Long Term Support) line.
