fusion-tokens

Dependency injection tokens for Fusion.js.

Fusion.js dependency injection is based on tokens rather than strings. This avoids naming collision issues. This package provides utilities to create named tokens, as well as common tokens that are used by packages maintained by the Fusion.js team.

API

FetchToken

import {FetchToken} from 'fusion-tokens';

A token for a fetch implementation.

Types

type Fetch = (input: string, options: Object) => Promise<Response>

Typically, fetch or a polyfill such as unfetch.

LoggerToken

import {LoggerToken} from 'fusion-tokens';

A token for a logger implementation.

Types

type Logger = {
  log(level: string, arg: any): void,
  error(arg: any): void,
  warn(arg: any): void,
  info(arg: any): void,
  verbose(arg: any): void,
  debug(arg: any): void,
  silly(arg: any): void,
}

Typically, console or a logger library such as Winston.

SessionToken

import {SessionToken} from 'fusion-tokens';

A token for a session implementation.

Types

type Session = {
  from(ctx: Context): {
    get(key: string): any,
    set(key: string, val: any): void,
  },
}

Typically, the service provided by fusion-plugin-jwt or a custom wrapper around similar key-value store APIs (such as Redis).

CacheToken

import {CacheToken} from 'fusion-tokens';

A token for a caching implementation.

Types

type Cache = {
  get(key: string): Promise<mixed>,
  set(key: string, val: any): Promise<mixed>,
  del(key: string): Promise<mixed>,
}

Standard API for caching.
