## Warning!
This package is still under heavy development.
As far as I am aware, it works as intended.
API can be considered as non-existent.
Only the command has any level of support for now.

## Installation
Install svelte2dts and its peer deps
```sh
npm i -D svelte2dts svelte2tsx typescript
```
## Usage
After installing, you can invoke the command via npx or package.json.

### Via CLI
Read all svelte files from `./src` and generate d.ts files in `./types`
```sh
npx svelte2dts --overwrite --runOnTS --declarationDir ./types ./src
```
Show help
```sh
npx svelte2dts --help
```
## Configuring
### package.json
Point package.json to the declarationDir and outDir. This is required to get the svelte VS-Code extension working properly. Note that they should not point into the same directory
```json
{
  ...
  "svelte": "./preprocessed/index.js",
  "types": "./types/index.d.ts",
  ...
}
```
### tsconfig.json
Be sure to set declarationDir and outDir to different locations.
```json
{
  "compilerOptions": {
    "strict": true,
    "outDir": "./preprocessed",
    "declaration": true,
    "declarationDir": "./types"
  },
}
```

Note that with the above setup, you no longer need to specify `--declarationDir` in the command!
```sh
npx svelte2dts --overwrite --runOnTS ./src
```

## Purpose
The only type of svelte components that are truly sharable are
ones written in pure svelte, with no preprocessors such as typescript.
As such, it is necessary to preprocess your components before publishing them. But sadly, `svelte-preprocess` removes all typings and does not generate any d.ts files. This is where we come in. We generate d.ts files for your sharable svelte components so your typings do not go to waste!

## PITAs
#### Separate `types` directory is required
You ***MUST*** use a separate directory for types
if you want the svelte plugin for vscode to work.

#### Markup preprocessors are not supported
If you have configured svelte to use a markup preprosessor by default (such as pug), you will
have to:

1) run the markup preprocessors
2) run us on their output
3) finish preprocessing to create your sharable component.

I am considering writing a svelte preprocessor
to intercept the code going into svelte-preprocess.typescript
and generate the declarations from that.

#### `tsc` is still required
We only emit declarations for now.
We *do not* compile your typescript into the configured outDir!
As there are no real limitations stopping us from doing so
we might add this feature in the future

#### src/MyComponent.svelte.d.ts is not copied to declarationDir
Typescript ***never*** copies d.ts files from src into declarationDir.
We are trying not to deviate from their decisions too much.
As such, if you want d.ts or svelte.d.ts files copied into declarationDir,
you will need to do so with separate command.

#### My component is still not sharable!
Our only goal is to generate the sharable typings for your code.
You will still require another package or script to generate a
sharable component.
A package that does both at the same time is next on my list to tackle

## Q&A
#### My component is well typed in Vs-Code when used in `.ts` files, but not in `.svelte` files
Your `types` directory should not contain anything other than `.d.ts` and `.svelte.d.ts` files. If both `Component.svelte` and `Component.svelte.d.ts` exist, the svelte plugin will load the types from `Component.svelte`. To further the confusion, typescript will properly load types from the `Component.svelte.d.ts` file, causing types to work in `.ts` files even though they would not in `.svelte` files.

The solution is to specify both
the `svelte` and `types` field in `package.json` [as documented here](#packagejson) and to ensure there are no `.svelte` files in the types directory.
