Lentils 🥘
A miscellaneous hodge-podge of TypeScript utilities. Designed to be usable in source form (the build step happens in the dependent projects, not in this one).
As published on npm, this package includes two versions of each file - ES modules and CommonJS. For example, common/types/checks.ts gets published both as @drmercer/lentils/cjs/common/types/checks (CommonJS) and as @drmercer/lentils/esm/common/types/checks (ES module). This is because ES modules are more modern and provide smaller bundles with tools like Webpack (in my experience), while CommonJS modules are more broadly compatible.
Using in Deno
To use these utilities in Deno, I recommend using esm.sh to compile them into ES modules with Deno typings headers included. You'll have to use the CommonJS version of the files, because esm.sh doesn't properly compile the ES module kind for some reason. (It's probably because the package.json doesn't have "type": "module", for CommonJS Node compatibility).
import { isNonNull } from 'https://esm.sh/@drmercer/lentils/cjs/common/types/checks.js';Using in Node
To use these utilities in Node, just add them to your project:
yarn add @drmercer/lentils
and then import the CommonJS files like so:
const { isNonNull } = require('@drmercer/lentils/cjs/common/types/checks');
// OR, if you're using TS, you can probably do this:
import { isNonNull } from '@drmercer/lentils/cjs/common/types/checks';Using in the browser via Webpack (and probably other bundlers)
In Webpack, you can import the esm/ version of the file you need, to get smaller output builds. The cjs/ files should also work just fine, if you prefer.
import { isNonNull } from '@drmercer/lentils/esm/common/types/checks';If you want to write code that can be used in both Node and the browser while preserving the Webpack benefits of ES modules, you can probably use Webpack's alias feature to convert cjs/ imports to esm/ imports at compile time.
Using in the browser directly
You can probably use esm.sh for direct ES module usage in the browser, just like in Deno. You also could try using the esm/ version via a CDN like unpkg, which doesn't do compiling like esm.sh does.
import { isNonNull } from 'https://esm.sh/@drmercer/lentils/cjs/common/types/checks.js';
A note about missing dependencies
Some of the code in this library depends on other libraries, like turndown. If you run into "missing dependency" errors, check the devDependencies in package.json for the version to use. I used devDependencies instead of peerDependencies or optionalDependencies because I don't want those deps to be installed by default in projects that use this library, in case they're not used, and I don't want to give unnecessary errors/warnings when installing this library in a project.
