Imagine a directory structure like this:
module
index.js
project
main.js
file.yaml
Imagine further that inside the module/index.js file, there is this code:
const fs = require('fs');
exports.test = function() {
// How should I *dynamically* reference the caller's app root directory?
console.log(fs.readFileSync('file.yaml', 'utf8'));
}
Inside the project/main.js file, there is this code:
const x = require('./module');
x.test();
And inside the project/file.yaml file, there is this code:
foo: bar
I want x.test(); to output the contents of project/file.yaml, somehow dynamically referencing the caller's root directory.
Is this what you wanted? __dirname gives the root dir of this file. So, no matter where this function gets called it will have correct location of file.yaml.
const fs = require('fs');
exports.test = function(fileLocation) {
// How should I *dynamically* reference the caller's app root directory?
console.log(fs.readFileSync(fileLocation), 'utf8'));
}
// Calling location
test(path.join(__dirname, './file.yaml')
