Using node modules in MongoBooster

Question:

Can I use node modules in MongoBooster? I want to use axios in my script. And, Do I have to install node module globally?

Answer:

Yes, You can use pure JS node modules in MongoBooster. And, you don't need to install node modules globally.

  1. Launch MongoBooster.
  2. Execute Main Menu -> Help -> Open the Executable Directory (or "Open User Data Directory" in the old version)
  3. New Terminal at this folder
1
npm i axios  # run it in MongoBooster user data directory

After successfully installing this package in the MongoBooster User Data Directory, you can require and access it in the MongoBooster script.

const axios=require("axios");
let rst=await (axios.get('https://api.github.com/users/github'));//await promise The "await" is a build-in method in MongoBooster. refer to: https://www.mongobooster.com/blog/using-functions-with-async-callback
console.log(rst.data);

The "await" is a build-in method in MongoBooster. You can use it to await a promise or a promise array.

Run it and got result.

Use your own javascript files

NoSQLBooster supports CommonJS module, each file is treated as a separate module. For example, consider a file named "c://test/myproject/utils.js"

c://test/myproject/utils.js

const replaceStr = (str, char, replacer) => {
  const regex = new RegExp(char, "g")
  const replaced = str.replace(regex, replacer)
  return replaced
}
exports.replaceStr =  replaceStr;

then import "c://test/myproject/utils.js" in your script.

const {replaceStr}= require("c://test/myproject/utils.js");
console.log(replaceStr("hello world","world","nosqlbooster"));  //hello nosqlbooster

Now, you can assemble packages like building blocks in your MongoDB shell script. The npm registry hosts almost half a million packages of free, reusable code — the largest software registry in the world.
