wnfs posts

Use Fission as storage for post objects with associated blobs.

install

npm i -S @ssc-hermes/wnfs-post

test

Run tests with test/index.ts:

npm test

Pass in the test file to run

npm test -- test/friendship.ts

example

create

Use .create, not the constructor, to make a new instance, because it is async

import * as wn from 'webnative'
const APP_INFO = { name: 'testing', creator: 'test' }
const wnfsPosts = await WnfsPosts.create(wn, APP_INFO)

create a post

wnfsPost.post will write a given post and blob to your wnfs filesystem, and then return the post.

import * as wn from 'webnative'
import { test } from 'tapzero'
import { writeKeyToDid, createUsername, verify } from 'wnfs-post/util'
import { WnfsPosts } from 'wnfs-post'

test('make a post', async t => {
    const APP_INFO = { name: 'testing', creator: 'test' }

    // use `.create` instead of `new` because it is async
    const wnfsPosts = await WnfsPosts.create(wn, APP_INFO)

    const post = await wnfsPosts.post(file, {
        text: 'testing'
    })

    t.ok(wnfsPosts, 'should create a wnfsPosts object')
    t.equal(post.author, await writeKeyToDid(wnfsPosts.program.components.crypto),
        'should have the right author in the post')
    t.equal(post.content.type, 'post', 'should set content.type')
    t.equal(post.content.text, 'testing', 'should set content.text')
    t.equal(post.username, wnfsPosts.username, 'should have the username in the post')
    t.equal(await verify(post.author, post), true, 'should verify the post')
})

verify a post

import { verify } from 'wnfs-post/util'

// const post = { author: '', signature: '', ... }
const isValid = await verify(post.author, post)

create a username

This will create a unique 32 character string that will be used for DNS, and is unique per account (not per machine).

import * as wn from 'webnative'
import { createUsername } from 'wnfs-post/util'

const program = await wn.program({
    namespace: { name: 'test', creator: 'test' }
})
const username = await createUsername(program.components.crypto)
