# Treeche 🌴

## What is this

**Tree** shakable **Che**cker.

check your module is tree-shakable or not, in each module and reduce bundle size!!

## Feature ✨

- typescript support

- you can check in each file

- you can check with the unique entrypoint

- glob pattern support

- pretty diagnostics report.

## How to use 🔧

```bash

npm install treeche -D // TBD

treeche "**/*.ts" --excludes "node_modules" "**/*.test.ts"

```

## Example 📕

```typescript

// this is not tree-shakable because have side-effect

const currentYear = new Date().getFullYear();

export function getCurrentYear() {

    return `Year ${currentYear}`

}

```

```bash

treeche "~~~"

```

log

```bash

🚨 ~/application/side_effect.ts is not tree-shakable due to the following code:

\`\`\`

const currentYear = new Date().getFullYear();

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

\`\`\`

```

if you fix this code such above

```typescript

// this is tree-shakable because this does not have side-effect

export function getCurrentYear(currentYear: string) {

    return `Year ${currentYear}`

}

```

log

```bash

Congratulation 🎉 All files are tree-shakeable ✨

```

|:--:|:--:|:--:|:--:|

|argument|inputs|input files to check tree-shakable. you can use Node glob pattern| treeche "src/**/*.ts"|

|option|excludes|excludes files to filter from inputs. you can use Node glob pattern| treeche "src/**/*.ts" --e "node_modules"|

|option|entry point|the unique entry point to check tree-shakable. if you specify input with this, treeche will bundle so you can check tree-shakable also in node_modules| treeche --entry-point ./src/main.ts|
