I have an Azure function and a file called configAPI.json which are located in the same folder as shown in the image below.

I want to read the latter with the following code based on this post How can i read a Json file with a Azure function-Node.js but the code isn't working at all because when I try to see if there's any content in the configAPI variable I encounter undefined:

module.exports = async function (context, req) {
    const fs = require('fs');
    const path = context.executionContext.functionDirectory   '//configAPI.json';
    configAPI= fs.readFile(path, 'utf-8', function(err, data){
        if (err) {
            context.log(err);
        }
        var result = JSON.parse(data);
        return result
    });

   for (let file_index=0; file_index<configAPI.length; file_index  ){
       // do something

  }
context.log(configAPI);
}

What am I missing in the code to make sure I can read the file and use it in a variable in my loop?

CodePudding user response：

functionDirectory - give you path to your functionS app then you have your single function

I think you should do:

const path = context.executionContext.functionDirectory   '\\configAPI.json';

In case you want to parse your json file you should have:

const file = JSON.parse(fs.readFileSync(context.executionContext.functionDirectory   '\\configAPI.json'));

PS. context has also variable functionName so other option to experiment would be:

    const path = context.executionContext.functionDirectory   
  '\\'  context.executionContext.functionName   '\\configAPI.json';
