Introducing Denoify - The Major NPM Modules Available to Deno

Wouldn’t it be great to have a tool able to make all the major NPM modules available to Deno?
Although it is quite easy to port a module, maintaining two codebases is a chore. Hence Denoify, a build tool aimed at NPM package authors that take as input a TypeScript codebase that was meant to target node and/or the web and spits out a modified version of the source files ready to be deployed as a Deno module.
The built tools come hand in hand with a GitHub action CI setup that takes charge of publishing on both Deno and NPM.
During this talk, I will show what the tool is capable of today, what it could be capable of tomorrow, and the help it needs from the opensource community to get there.

Denoify: For NPM Module Authors That Would Like to Support Deno

What it is

A build tool that takes as input a TypeScript codebase that was meant to target node and/or the web and spits out a modified version of the source files ready to be deployed as a Deno module.

If you are just looking for a quick way to load NPM modules in your Deno project you can check out CommonJS module Loading, unlike Denoify, it won’t give you types definitions, it will involve node_modules/ and require --allow-read but it will also be easier to get working.

This tool is mainly for NPM module maintainer, to enable them to bring first-class citizen Deno support to their module and doing so without introducing breaking changes.

Motivations

• Although it is quite easy to port a module to Deno no one wants to maintain two codebase.
• Wouldn’t it be great to have a tool able to bring Deno support to NPM modules?

Example of modules using Denoify

Modules that have been made cross-runtime using Denoify:

• EVT
• run-exclusive

Limitations

Coming up next is a detailed guide on how to set up denoify with your project and how to publish on deno.land/x but before anything here are the current limitations you need to be aware of.

• If your module is vanilla JS it needs to be ported to TypeScript first. (1)
• Not all Node’s builtin are supported yet. (2)
• You will need to fork and denoify(3) manually each of your module’s (not dev) dependencies.
• For the dependencies that can’t easily be denoified you will need to write a partial Deno port of the bits your module needs.
• require() is not yet supported.
• You can’t (yet) fs.readFile files that are part of the module ( files inside a res/ directory for example ). (4)

(1) Don’t be afraid, renaming your source with _.ts_ and dropping some _any_ here and there will do the trick. You will be able to pull it off even if you aren’t familiar with typescript. Ref

(2) You can consult here the current state of the Node’s builtin support.

(3) Glossary: To ‘denoify’ a module is the process of using this tool to generate a deno distribution of a module and to publish it on GitHub. How to do that is documented in details.

(4) In Deno the files that forms your module won’t be pre-fetched and placed in _node_module_ like in node so you won’t be able to access files that are not on the disk.

GUIDES

Setting up an existing project

Check out this repo to see in practice how to set up Denoify in your project.

Starting a project from scratch

denoify_ci is a template repo that automates the boring and tedious tasks of:

• Filling up the package.json
• Setting up TypeScript and Denoify.
• Writing a README.md with decent presentation and instructions on how to install/import your module in different environments.
• Testing with multiple Node and Deno versions before publishing.
• Publishing on NPM and deno.land/x ( via GitHub releases ).
