Meme3 NPM | npm.io

meme3.js - Popcateum JavaScript API

This is the Popcateum JavaScript API which connects to the Generic JSON-RPC spec.

Please read the documentation for more.

Installation

Node

npm install meme3

Yarn

yarn add meme3

In the Browser

Use the prebuilt dist/meme3.min.js, or build using the meme3.js repository:

npm run build

Then include dist/meme3.min.js in your html file. This will expose Meme3 on the window object.

Usage

// In Node.js
const Meme3 = require('meme3');

let meme3 = new Meme3('ws://localhost:9507');
console.log(meme3);
> {
    pop: ... ,
    shh: ... ,
    utils: ...,
    ...
}

Additionally you can set a provider using meme3.setProvider() (e.g. WebsocketProvider):

meme3.setProvider('ws://localhost:9507');
// or
meme3.setProvider(new Meme3.providers.WebsocketProvider('ws://localhost:9507'));

There you go, now you can use it:

meme3.pop.getAccounts().then(console.log);

Usage with TypeScript

We support types within the repo itself. Please open an issue here if you find any wrong types.

You can use meme3.js as follows:

import Meme3 from 'meme3';
const meme3 = new Meme3('ws://localhost:9507');

If you are using the types in a commonjs module, like in a Node app, you just have to enable esModuleInterop and allowSyntheticDefaultImports in your tsconfig for typesystem compatibility:

"compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    ....

Trouble shooting and known issues.

Meme3 and Angular

If you are using Ionic/Angular at a version >5 you may run into a build error in which modules crypto and stream are undefined

a work around for this is to go into your node-modules and at /angular-cli-files/models/webpack-configs/browser.js change the node: false to node: {crypto: true, stream: true} as mentioned here

Another variation of this problem was an issue opned on angular-cli: https://github.com/angular/angular-cli/issues/1548
