Looking for some insight on retrieving process information from a VPS with PM2. However, the JSON string returned by PM2 is malformed, making it impossible to run JSON.parse().
An example of the output provided by PM2:
'{data: 0, informations: "hello", name: "test"}'
If you are familiar with how JSON parsing works, you'll understand the issue at hand - this string cannot be parsed.
Do you have any suggestions for resolving this issue using an alternative function?
Thank you in advance.
It appears that the data you are working with is encoded using either regular JavaScript or JSON5 format. JSON5 provides a flexible way to define JSON objects in a structure similar to standard JavaScript, allowing for easier readability and manipulation. To handle this data, consider installing the JSON5 library and use JSON5.parse() method for parsing. For more information about JSON5, please visit:
Looking for a solution to handle non-json formats? Here's a clever trick - ensure that keys are enclosed in double quotes...
function convertNonJson(string){
return JSON.parse(string
.replace(/\s|"/g, '') // Eliminate spaces and double quotes
.replace(/(\w+)/g, '"$1"') // Introduce double quotes everywhere
.replace(/"(\d+)"/g, '$1') // Remove double quotes around integers
)
}
// Test the function
let inputString = '{data: 0, information: "hello", name: "example"}'
let outputObject = customParse(inputString)
// Output
console.log(outputObject)
console.log(outputObject.data)
console.log(outputObject.information)
console.log(outputObject.name)If you're dealing with a string in JSON5 format instead of regular JSON format, parsing it in JavaScript requires using a library that supports JSON5 like json5.
To get started, follow these steps:
npm install json5
import json5 from 'json5';
const str = "{data: 0, informations: 'hello', name: 'test'}";
const obj = json5.parse(str);
Alternatively, consider utilizing Hjson for parsing the string. While JSON5 is more commonly used and established than Hjson, the latter can be beneficial for configuration files that prioritize human readability and ease of use.
