カスタムフィードを作ってみる？

１．ソース修正

Githubから取得

code:shell

code:.env

# Whichever port you want to run this on

FEEDGEN_PORT=3000

# Change this to use a different bind address

FEEDGEN_LISTENHOST="localhost"

# Set to something like db.sqlite to store persistently

# ファイルに保存する場合はファイルパス

FEEDGEN_SQLITE_LOCATION=":memory:"

# Don't change unless you're working in a different environment than the primary Bluesky network

FEEDGEN_SUBSCRIPTION_ENDPOINT="wss://bsky.social"

# Set this to the hostname that you intend to run the service at

FEEDGEN_HOSTNAME="${カスタムフィードのドメイン}"

# Set this to the DID of the account you'll use to publish the feed

# You can find your accounts DID by going to

FEEDGEN_PUBLISHER_DID="${カスタムフィードを公開するユーザのdid}"

# Only use this if you want a service did different from did:web

# FEEDGEN_SERVICE_DID="did:plc:abcde..."

サンプルとして以下のコードを修正した単純なもので説明する。

下記は「cat」「dog」を含んだ投稿をフィードとしています。src/algos/animals.tsはwhats-alf.tsをコピーして作成

code:src/algos/animals.ts(whats-alf.tsをコピーしたファイル)

- export const shortname = 'whats-alf'

+ export const shortname = 'animals' //レコード名(何でも良い。但し、scripts/publishFeedGen.tsのrecordNameと同じ値)

code:src/algos/index.ts

import { AppContext } from '../config'

import {

QueryParams,

OutputSchema as AlgoOutput,

} from '../lexicon/types/app/bsky/feed/getFeedSkeleton'

-import * as whatsAlf from './whats-alf'

+import * as animals from './animals'

type AlgoHandler = (ctx: AppContext, params: QueryParams) => Promise<AlgoOutput>

const algos: Record<string, AlgoHandler> = {

}

code:subscription.ts

const postsToDelete = ops.posts.deletes.map((del) => del.uri)

const postsToCreate = ops.posts.creates

.filter((create) => {

+ if (create.record.text.toLowerCase().includes(' cat ')) {

+ return true

+ }

+ if (create.record.text.toLowerCase().includes(' dog ')) {

+ return true

+ }

+ return false

})

.map((create) => {

// map alf-related posts to a db row

return {

uri: create.uri,

実行

code:sh

yarn start

２．Nginx設定

code:default

server {

listen 443 ssl;

location / {

add_header Access-Control-Allow-Origin "*";

add_header Access-Control-Allow-Methods "POST, GET, OPTIONS";

add_header Access-Control-Allow-Headers "Origin, Authorization, Accept";

add_header Access-Control-Allow-Credentials true;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

listen 80;

root /var/www/html;

# Add index.php to the list if you are using PHP

index index.html index.htm index.nginx-debian.html;

server_name _;

}

カスタムフィードに直接アクセスする場合、

bluesky経由でアクセスする場合、

scripts/publishFeedGen.tsに必要事項を記入して実行でBlueskyに登録されるはず。

code:scripts/publishFeedGen.ts

// YOUR bluesky handle

// Ex: user.bsky.social

const handle = '${カスタムフィードを公開するユーザのhandle}'

// YOUR bluesky password, or preferably an App Password (found in your client settings)

// Ex: abcd-1234-efgh-5678

const password = '${カスタムフィードを公開するユーザのAppPassword}'

// A short name for the record that will show in urls

// Lowercase with no spaces.

// Ex: whats-hot

const recordName = '${algos/animals.tsで設定したshortName}'

// A display name for your feed

// Ex: What's Hot

const displayName = '${フィードの名前}'

// (Optional) A description of your feed

// Ex: Top trending content from the whole network

const description = ' ${フィードの説明}'

// (Optional) The path to an image to be used as your feed's avatar

// Ex: ~/path/to/avatar.jpeg

const avatar: string = '${フィードのアバターのパス}'

以下のコマンドで登録

code:sh

yarn publishFeed
