Cloudflare 通过 CloudflareWorkers 提供无服务器计算服务，后者是用于构建和部署在 Cloudflare 边缘网络上运行的JavaScript函数的平台。在边缘（尽可能靠近最终用户）运行代码有助于减少延迟并提高应用程序性能。每个 Worker 都可以修改并响应HTTP请求。
Blueboat就是CloudflareWorkers的开源替代品，旨在成为无服务器Web应用开发者友好的多租户平台。
一个简单的Blueboat应用程序如下所示：Router.get("/",req=>newResponse("helloworld"));Router.get("/example",req=>{returnfetch("https://example.com");});Router.get("/yaml",req=>{constres=TextUtil.Yaml.stringify({hello:"world",});returnnewResponse(res);});使用托管服务的快速入门安装 bbcli对于Linux：curl-sSL-o/tmp/bbcli.tar.gzhttps://github.com/losfair/bbcli/releases/download/v0.1.0-alpha.1/bbcli_linux.tar.gztar-xzvf/tmp/bbcli。tar.gz-C~chmod+x~/bbcli&&rm/tmp/bbcli.tar.gz对于macOS：curl-sSL-o/tmp/bbcli.tar.gzhttps://github.com/losfair/bbcli/releases/download/v0.1.0-alpha.1/bbcli_macos.tar.gztar-xzvf/tmp/bbcli。tar.gz-C~chmod+x~/bbcli&&rm/tmp/bbcli.tar.gz克隆示例项目gitclonehttps://github.com/losfair/blueboat-examples部署项目cdblueboat-examples/hello-worldnpmi~/bbclideploy--vars./hosted.vars.yaml部署Blueboat实例先决条件Docker用于存储应用程序配置和代码的S3兼容bucket用于存储 bbcp 元数据的MySQL服务（可选）用于流式传输日志的Kafka服务部署示例：version:"3"services:blueboat:image:ghcr.io/losfair/blueboat:latestuser:daemonports:-"127.0.0.1:3000:3000"entrypoint:-/usr/bin/blueboat_server--l-0.0.0.0:3000---s3-bucket-my-bucket.example.com---s3-region-us-east-1#Uncommentthisifyouuseanon-AWSS3-compatibleservice.#---s3-endpoint#-https://minio.example.com#UncommentthistoenableloggingtoKafka.#---log-kafka#-net.univalent.blueboat-log.default:0@kafka:9092#Uncommentthistoenablegeoipinformationinthe`x-blueboat-client-country`,#`x-blueboat-client-city`,`x-blueboat-client-subdivision-1`and#`x-blueboat-client-subdivision-2`requestheaders.#---mmdb-city#-/opt/blueboat/mmdb/GeoLite2-City.mmdb#UncommentthistoenableautomaticWikipediaIPblocklistqueryinthe#`x-blueboat-client-wpbl`requestheader.#Thedatabaseisgeneratedwithhttps://github.com/losfair/wpblsync.#---wpbl-db#-/opt/blueboat/wpbl/wpbl.dbenvironment:RUST_LOG:infoAWS_ACCESS_KEY_ID:your_s3_access_key_idAWS_SECRET_ACCESS_KEY:your_s3_secret_access_key#Uncommentthistoenabletextrenderingincanvas.#SMRAPP_BLUEBOAT_FONT_DIR:/opt/blueboat/fonts
