A CDK construct library for Amazon S3 Vectors. This construct simplifies the creation of vector buckets, vector indexes with full configuration options, and Amazon Bedrock knowledge bases using S3 Vectors as the underlying vector store.

# tslib

This is a runtime library for [TypeScript](https://www.typescriptlang.org/) that contains all of the TypeScript helper functions.

This library is primarily used by the `--importHelpers` flag in TypeScript.
When using `--importHelpers`, a module that uses helper functions like `__extends` and `__assign` in the following emitted file:

```ts
var __assign = (this && this.__assign) || Object.assign || function(t) {
    for (var s, i = 1, n = arguments.length; i < n; i++) {
        s = arguments[i];
        for (var p in s) if (Object.prototype.hasOwnProperty.call(s, p))
            t[p] = s[p];
    }
    return t;
};
exports.x = {};
exports.y = __assign({}, exports.x);

```

will instead be emitted as something like the following:

```ts
var tslib_1 = require("tslib");
exports.x = {};
exports.y = tslib_1.__assign({}, exports.x);
```

Because this can avoid duplicate declarations of things like `__extends`, `__assign`, etc., this means delivering users smaller files on average, as well as less runtime overhead.
For optimized bundles with TypeScript, you should absolutely consider using `tslib` and `--importHelpers`.

# Installing

For the latest stable version, run:

## npm

```sh
# TypeScript 3.9.2 or later
npm install tslib

# TypeScript 3.8.4 or earlier
npm install tslib@^1

# TypeScript 2.3.2 or earlier
npm install tslib@1.6.1
```

## yarn

```sh
# TypeScript 3.9.2 or later
yarn add tslib

# TypeScript 3.8.4 or earlier
yarn add tslib@^1

# TypeScript 2.3.2 or earlier
yarn add tslib@1.6.1
```

## bower

```sh
# TypeScript 3.9.2 or later
bower install tslib

# TypeScript 3.8.4 or earlier
bower install tslib@^1

# TypeScript 2.3.2 or earlier
bower install tslib@1.6.1
```

## JSPM

```sh
# TypeScript 3.9.2 or later
jspm install tslib

# TypeScript 3.8.4 or earlier
jspm install tslib@^1

# TypeScript 2.3.2 or earlier
jspm install tslib@1.6.1
```

# Usage

Set the `importHelpers` compiler option on the command line:

```
tsc --importHelpers file.ts
```

or in your tsconfig.json:

```json
{
    "compilerOptions": {
        "importHelpers": true
    }
}
```

#### For bower and JSPM users

You will need to add a `paths` mapping for `tslib`, e.g. For Bower users:

```json
{
    "compilerOptions": {
        "module": "amd",
        "importHelpers": true,
        "baseUrl": "./",
        "paths": {
            "tslib" : ["bower_components/tslib/tslib.d.ts"]
        }
    }
}
```

For JSPM users:

```json
{
    "compilerOptions": {
        "module": "system",
        "importHelpers": true,
        "baseUrl": "./",
        "paths": {
            "tslib" : ["jspm_packages/npm/tslib@2.x.y/tslib.d.ts"]
        }
    }
}
```

## Deployment

- Choose your new version number
- Set it in `package.json` and `bower.json`
- Create a tag: `git tag [version]`
- Push the tag: `git push --tags`
- Create a [release in GitHub](https://github.com/microsoft/tslib/releases)
- Run the [publish to npm](https://github.com/microsoft/tslib/actions?query=workflow%3A%22Publish+to+NPM%22) workflow

Done.
