0.21.0

New Features

Client Fetch Authentication

The azle/http_client import has been introduced. It exports a toJwt function that can be used for client-side authentication using fetch and the Authorization header.

Examples:

• internet_identity
• fetch_ic

Canister Fetch HTTP

Canisters can now perform outgoing HTTP requests using fetch.

Examples:

• http_outcall_fetch
• outgoing_http_requests
• ethereum_json_rpc

Canister Fetch File

Canisters can now request files from their local filesystem using fetch:

Examples:

• file_protocol
• tfjs

Hybrid HTTP/Candid Canisters

It is now easier to compose hybrid HTTP/Candid canisters e.g. an HTTP-based canister that exposes Candid methods, or a Candid canister that exposes HTTP endpoints.

Examples:

• hybrid_canister

Optional Server Export

export default Server is no longer required for HTTP-based canisters.

Large Asset Uploads

Files up to 2 GiB in size can now be uploaded into a canister's local filesystem. There are some issues around authentication, not all dfx identity types are currently supported. We will soon release a new version of Azle with an improvement to this problem.

Examples:

• audio_and_video
• large_files

Range Requests

Canisters can now easily respond to range requests, enabling experimentation with video streaming use cases:

Examples:

• audio_and_video

Native Compilation

A --native-compilation build flag allows for a canister to skip Podman and use a locally installed build environment.

Examples:

• key_value_store
• primitive_types
• stable_structures
