Background

Superface (super-interface) is a higher-order API, an abstraction on top of the modern APIs like GraphQL and REST. Superface is one interface to discover, connect, and query any capabilities available via conventional APIs.

Through its focus on application-level semantics, Superface decouples the clients from servers, enabling fully autonomous evolution. As such it minimizes the code base as well as errors and downtimes while providing unmatched resiliency and redundancy.

Superface allows for switching capability providers without development at a runtime in milliseconds. Furthermore, Superface decentralizes the composition and aggregation, and thus creates an Autonomous Integration Mesh.

Motivation behind Superface is nicely described in this video from APIdays conference.

You can get more information at https://superface.ai and https://superface.ai/docs. Superface AST definitions for Javascript/Typescript. The types in this repository define the common language that the Superface parser produces and the Superface SDK interprets.

Install

Install the ast into one of your projects:

yarn add @superfaceai/ast

Usage

import { ProfileDocumentNode } from '@superfaceai/ast';
const { Source, parseProfile } = require('@superfaceai/parser');

const content = `
name = "test"
version = "0.1.0"

usecase Test {}
`;
const source = new Source(content);
const result: ProfileDocumentNode = parseProfile(source);

Security

Superface is not man-in-the-middle so it does not require any access to secrets that are needed to communicate with provider API. Superface CLI only prepares super.json file with authorization fields in form of environment variable. You just set correct variables and communicate directly with provider API.

You can find more information in SDK repository.

Support

If you need any additional support, have any questions or you just want to talk you can do that through our documentation page.

Development

When developing, start with cloning the repository using git clone https://github.com/superfaceai/ast-js.git (or git clone [email protected]:superfaceai/ast-js.git if you have repository access).

After cloning, the dependencies must be downloaded using yarn install or npm install.

Now the repository is ready for code changes.

The package.json also contains scripts (runnable by calling yarn <script-name> or npm run <script-name>):

• test - run all tests
• lint - lint the code (use lint:fix to run autofix)
• format - check the code formatting (use format:fix to autoformat)
• prepush - run test, lint and format checks. This should run without errors before you push anything to git.

Lastly, to build a local artifact run yarn build or npm run build.
