const port = process.env.PORT; // 读取环境变量 PORT const env = process.env.ENV; // 读取环境变量 ENV console.log(`Your port is ${port} on ${env} environment`); 然后在package.json里就不再需要使用命令行(也就不需要cross-env了) { "name": "learn-env-vars", "version": "0.0.0", ...
This sets the keys in the Docker container, which then deploy's to an ELB using a bash script and the AWS-CLI to commit, so I don't actually try to expose the env vars, but eb deploy sure does and it works. When trying to run a pipeline with the image: node:lates...
I guess maybe the only way to do that is by specifying something special in server.js for the frontend script file, rather than serving it statically, but if so, then that's the instruction I'm looking for, not how to actually access the env vars on the server. Sorry for any confusio...
通过dotenv这个 npm 包可以读取 .env 文件的配置到 Nodejs 程序中。 npm install dotenv --save 安装后,直接调用它解析,就可以从环境变量中拿到 .env 文件的配置信息了: require("dotenv").config(); var MongoClient = require("mongodb").MongoClient; // Reference .env vars off of the process.env o...
This PR #23583 introduced a problem that env vars are read on startup (during the runtime creation). This is not great, because some embedders, might not provide API to read env vars or haven't captured env vars yet. We need to read this env var explicitly during intialization (or ...
可以使用process.env.VARIABLE_NAME的语法来访问环境变量。 Node.js的环境变量在开发中具有广泛的应用场景,其中一些示例包括: 应用程序配置:通过使用环境变量,可以动态配置应用程序的行为,例如数据库连接信息、API密钥等。这样可以提高应用程序的可移植性和安全性。 多环境部署:通过在不同环境中设置不同的环境变量,可以...

"@typescript-eslint/no-unused-vars": "error", "no-dupe-class-members": "off" }, "globals": { "fetch": false } } 使用.env 来保存一些全局配置,像数据库地址等等 大部分项目都会使用 .env 来保存这些配置,这样如果需要修改这些配置,只需要修改 .env 这个文件就可以了。 而且 .env 一般在根目录...
