[英]Unable to configure MongoDB in Angular application that is using Express and Azure Cosmos DB
I am facing strange issue in configuring and using Azure CosmosDB MongoDB Api in angular application, the configuration and code is referred from https://docs.microsoft.com/en-us/azure/cosmos-db/tutorial-develop-mongodb-nodejs-part2 and https://johnpapa.net/angular-cosmosdb-1/ , though i was able to configure and run application with express when i am trying to configure and install Mongoose node module getting series of errors: I am facing strange issue in configuring and using Azure CosmosDB MongoDB Api in angular application, the configuration and code is referred from https://docs.microsoft.com/en-us/azure/cosmos-db/tutorial-develop-mongodb- nodejs-part2和https://johnpapa.net/angular-cosmosdb-1/ ,尽管当我尝试配置和安装 Mongoose 节点模块时,我能够使用 express 配置和运行应用程序出现一系列错误:
1) Cannot find module 'mongodb-extjson 2) Cannot find module 'bson-ext' 3) ENOENT: no such file or directory, access 'XXX\node_modules\bson-ext\lib\package.json 1)找不到模块'mongodb-extjson' 2)找不到模块'bson-ext' 3)ENOENT:没有这样的文件或目录,访问'XXX\node_modules\bson-ext\lib\package.json
I have tried re installing packages but no success.我尝试重新安装软件包但没有成功。
I am using Angular version 10 with mongoose version 5.11.14 i am getting error at compile time when trying to run it from vs code and trying to launch server/index.js on port 3000.我正在使用 Angular 版本 10 和 mongoose 版本 5.11.14 我在尝试从 vs 代码运行它并尝试在端口 3000 上启动 server/index.js 时在编译时出错。
Your help is greatly appriciated.非常感谢您的帮助。
You are getting 1 and 2 because the MongoDB driver checks for optional requirements during initialization.您得到 1 和 2 是因为 MongoDB 驱动程序在初始化期间检查可选要求。 You can F5 past them in VS Code.
您可以在 VS Code 中按 F5 跳过它们。 Or install them like so:
或者像这样安装它们:
node install mongodb-extjson
node install bson-ext
Number 3 is also due to an exception during startup. 3 号也是由于启动过程中的异常。 I have no clue to why this is missing but if you want to skip initial throws in the debugger you can start without debugging first and then "attach" to it.
我不知道为什么会丢失它,但如果你想跳过调试器中的初始抛出,你可以先不调试就开始,然后“附加”到它。 Like so:
像这样:
node --inspect --nolazy server/index.js
To attach to node with VSCode, make sure you have something like this in your.vscode\launch.json:要使用 VSCode 附加到节点,请确保在 your.vscode\launch.json 中有类似的内容:
{
"name": "Docker: Attach to Node",
"type": "node",
"request": "attach",
"port": 9229,
"address": "localhost",
"localRoot": "${workspaceFolder}",
"remoteRoot": "/",
"protocol": "inspector"
}
Many node modules test things at startup by throwing and catching.许多节点模块在启动时通过抛出和捕获来测试事物。 For example:
例如:
var hasStacks = false;
try {
throw new Error();
} catch (e) {
hasStacks = !!e.stack;
}
...and this leads to break in VS Code debugger. ...这会导致 VS Code 调试器中断。 So you might want to attach (ie press run "Docker: Attach to Node" after a few seconds.
所以你可能想要附加(即在几秒钟后按运行“Docker:附加到节点”。
