Using the SDK | Tigris Object Storage Documentation

On this page

Before you can use the SDK, make sure that you have followed the steps in the Getting Started guide.

Authentication

After you have created an access key, you can set the environment variables in your .env file:

TIGRIS_STORAGE_ACCESS_KEY_ID=tid_access_key_id

TIGRIS_STORAGE_SECRET_ACCESS_KEY=tsec_secret_access_key

TIGRIS_STORAGE_BUCKET=bucket_name

Alternatively, all methods accept an optional config parameter that allows you to override the default environment configuration:

type TigrisStorageConfig = {

bucket?: string;

accessKeyId?: string;

secretAccessKey?: string;

endpoint?: string;

};

Examples

Use environment variables (default)

const result = await list();

Override with custom config

const result = await list({

config: {

bucket: "my-bucket-name",

accessKeyId: "tigris-access-key",

secretAccessKey: "tigris-secret-key",

},
});

Override only specific values

const result = await get("object.txt", "string", {

config: {

bucket: "different-bucket",

},
});

Responses

All methods return a generic response of type TigrisStorageResponse. If there is an error, the error property will be set. If there is a successful response, the data property will be set. This allows for a better type safety and error handling.

type TigrisStorageResponse<T, E> = {

data?: T;

error?: E;

};

Example

const objectResult = await get("photo.jpg", "file");

if (objectResult.error) {

console.error("Error downloading object:", objectResult.error);

} else {

console.log("Object name:", objectResult.data?.name);

console.log("Object size:", objectResult.data?.size);

console.log("Object type:", objectResult.data?.type);

}

Uploading an object

put function can be used to upload a object to a bucket.

`put`

put(path: string, body: string | ReadableStream | Blob | Buffer, options?: PutOptions): Promise<TigrisStorageResponse<PutResponse, Error>>;

put accepts the following parameters:

path: (Required) A string specifying the base value of the return URL
body: (Required) A blob object as ReadableStream, String, ArrayBuffer or Blob based on these supported body types
options: (Optional) A JSON object with the following optional parameters:

`options`

Parameter	Required	Values
access	No	The access level for the object. Possible values are `public` and `private`.
addRandomSuffix	No	Whether to add a random suffix to the object name. Default is `false`.
allowOverwrite	No	Whether to allow overwriting the object. Default is `true`.
contentType	No	Set the content type of the object. If not provided, the content type will be inferred from the extension of the path.
contentDisposition	No	Set the content disposition of the object. Possible values are `inline` and `attachment`. Default is `inline`. Use `attachment` for downloadable files.
multipart	No	Pass `multipart: true` when uploading large objects. It will split the object into multiple parts and upload them in parallel.
abortController	No	An AbortController instance to abort the upload.
onUploadProgress	No	Callback to track upload progress: `onUploadProgress({loaded: number, total: number, percentage: number})`.
config	No	A configuration object to override the default configuration.

In case of successful upload, the data property will be set to the upload and contains the following properties:

contentDisposition: content disposition of the object
contentType: content type of the object
modified: Last modified date of the object
path: Path to the object
size: Size of the object
url: A presigned URL to the object if the object is uploaded with access set to private, otherwise unsigned public URL for the object

Examples

Simple upload

const result = await put("simple.txt", "Hello, World!");

if (result.error) {

console.error("Error uploading object:", result.error);

} else {

console.log("Object uploaded successfully:", result.data);

}

Uploading a large object

const result = await put("large.mp4", fileStream, {

multipart: true,

onUploadProgress: ({ loaded, total, percentage }) => {

console.log(`Uploaded ${loaded} of ${total} bytes (${percentage}%)`);

},

});

Prevent overwriting

const result = await put("config.json", configuration, {

allowOverwrite: false,

});

Cancel an upload

const abortController = new AbortController();

const result = await put("large.mp4", fileStream, {

abortController: abortController,

});

function cancelUpload() {

abortController.abort();

}

Downloading an object
