OR

yarn add outpost-sdk

Usage

const { createClient } = require('outpost-sdk')

Or with es6

Methods

createClient

Create an outpost client. Returns the methods available in the SDK.

const createClient = (options: createClientParams = defaultOptions): createClientResult

The result:

type createClientResult = {
  readonly getAllCommunities: () => Promise<readonly Community[]>;
  readonly getPosts: (params: getPostsParams) => Promise<getPostsResult>;
  readonly getChallenge: (
    params: getChallengeParams
  ) => Promise<getChallengeResult>;
  readonly getAuthToken: (
    params: getAuthTokenParams
  ) => Promise<getAuthTokenResult>;
  readonly getPostPreview: (
    params: getPostPreviewParams
  ) => Promise<getPostPreviewResult>;
  readonly uploadImage: (
    params: uploadImageParams
  ) => Promise<uploadImageResult>;
  readonly uploadPost: (params: uploadPostParams) => Promise<uploadPostResult>;
  readonly uploadComment: (
    params: uploadCommentParams
  ) => Promise<uploadCommentResult>;
  readonly getPost: (params: getPostParams) => Promise<getPostResult>;
};

getChallenge

Get a challenge from the outpost server so that it can verify a user owns their Ethereum address. Returns a string that the user must sign and send back to the server in getAuthToken.

getChallenge: (params: getChallengeParams) => Promise<getChallengeResult>

type getChallengeParams = { readonly address: string; };

type getChallengeResult = string;

getAuthToken

Get an authentication token to be able to access authenticated routes. Returns the users authentication token.

getAuthToken: (params: getAuthTokenParams) => Promise<getAuthTokenResult>;

type getAuthTokenParams = {
  readonly address: string;
  readonly signature: string;
};

type getAuthTokenResult = string;

getPosts

List all the posts of a specified community. Returns an array of posts.

getPosts: (params: getPostsParams) => Promise<getPostsResult>;

type getPostsParams = { readonly slug: string; };

type getPostsResult = readonly Post[];

type Post = {
  readonly id: string;
  readonly title: string;
  readonly subtitle: string;
  readonly timestamp: number;
  readonly txId: string;
  readonly featuredImg: string;
};

getPostPreview

Get the preview for a post.

getPostPreview: (params: getPostPreviewParams) => Promise<getPostPreviewResult>;

export type getPostPreviewParams = { readonly txId: string; };

type getPostPreviewResult = {
  readonly id: string;
  readonly title: string;
  readonly subtitle: string;
  readonly timestamp: number;
  readonly txId: string;
  readonly featuredImg: string | null;
  readonly canonicalLink: string;
};

uploadImage

Upload a base64 representation of an image file to arweave. Returns the transaction id of the upload.

uploadImage: (params: uploadImageParams) => Promise<uploadImageResult>;

type uploadImageParams = {
  readonly base64: string;
  readonly authToken: string;
};

type uploadImageResult = {
  readonly txId: string;
  readonly gateway: string;
};

Now you can view the image at

`https://${gateway}/${txId}`

Note: The gateway returned is the host of the gateway the image was uploaded to (i.e. 'arweave.net'). Transactions take about 2 minutes to be included in a block but Arweave's gateways ('arweave.net' and 'arweave.dev') optimistically store the transaction so it can be served immediately.

uploadPost

Upload a post to arweave.

uploadPost: (params: uploadPostParams) => Promise<uploadPostResult>;

type uploadPostParams = {
  readonly authToken: string;
  readonly communityTxId: string;
  readonly postUpload: {
    readonly canonicalLink: string;
    readonly postText: string;
    readonly subtitle: string;
    readonly timestamp: number;
    readonly title: string;
  };
};

type uploadPostResult = {
  readonly txId: string;
  readonly title: string;
  readonly postText: string;
  readonly subtitle: string;
  readonly timestamp: number;
  readonly canonicalLink: string;
  readonly community: {
    readonly name: string;
  };
  readonly user: {
    readonly address: string;
  };
};

getPost

Get a post.

uploadPost: (params: uploadPostParams) => Promise<uploadPostResult>;

type getPostParams = {
  readonly txId: string;
  readonly authToken: string;
};

getAllCommunities

Get all the publications (a.k.a. communities).

getAllCommunities: () => Promise<readonly Community[]>;
