ESBuild plugin for compiling typescript declarations

WARNING

This plugin was made to make it easier to build declarations without running two commands simultaneously. It will add a lot of overhead to your build time and should only really be used as a last resort.

- TSUP - Similar usage to this plugin, but more stable and configurable. A CLI tool wrapped around ESBuild rather than a plugin

Usage

``js
const { dtsPlugin } = require("esbuild-plugin-d.ts");
const { build } = require("esbuild");
// OR
import { dtsPlugin } from "esbuild-plugin-d.ts";
import { build } from "esbuild";

build({
entryPoints: ["./test/index.ts"],
outdir: "./dist",
plugins: [dtsPlugin({
// Optional options here
})]
})

`

The plugin uses the typescript compiler api. You don't need to enable declarations in your tsconfig.

The plugin does not enable incremental mode unless incremental is set to true in your tsconfig. When this is enabled, the plugin will automatically assume a tsbuildinfo file but will respect your config if set there.

Be aware that if you delete your dist folder and have incremental mode enabled, your declarations may not be built.

$3

This plugin has experimental declaration bundling support, to enable it, set experimentalBundling to true in the plugin's options as follows:


Note that this also requires you to set your entry points in ESBuild.

`js
build({
entryPoints: ["./test/index.ts"],
outdir: "./dist",
plugins: [dtsPlugin({
experimentalBundling: true
})]
})
`

Once proven to be stable, this will be enabled when bundle is set to true in ESBuild and will be documented properly.

$3

- outDir: string (DEPRECATED) - override the output directory - you should define declarationDir in your tsconfig instead. The plugin will also fall back to your tsconfig outDir or esbuild outdir
- tsconfig: string | object` - A path to your tsconfig or a tsconfig object. The plugin will automatically find your tsconfig if you don't specify one.

All other functionality is derived from your tsconfig
