I want to store debugged javascript code as a Json file, the debugged json file should have the information about the lineNumber, code on that line and local variables value for each step of the code execution.
Let's consider a simple example, I have a js code:
const add = (a, b) => {
return a + b;
}
console.log(add(5, 4))
After debugging this code I should get a json file somewhat similar to this:
[
{
"line_number": 1,
"code_one_line": "const add = (a, b) => {",
"variables": [
{
"variable_name": "add",
"variable_value": "undefined"
},
{
"variable_name": "a",
"variable_value": "undefined"
},
{
"variable_name": "b",
"variable_value": "undefined"
}
]
},
{
"line_number": 5,
"code_one_line": "console.log(add(5, 4))",
"variables": [
{
"variable_name": "add",
"variable_value": "(a, b) => { return a + b; }"
}
]
},
{
"line_number": 2,
"code_one_line": " return a + b;",
"variables": [
{
"variable_name": "a",
"variable_value": 5
},
{
"variable_name": "b",
"variable_value": 4
}
]
},
{
"line_number": 2,
"code_one_line": " return a + b;",
"variables": [
{
"variable_name": "a",
"variable_value": 5
},
{
"variable_name": "b",
"variable_value": 4
},
{
"variable_name": "Return value",
"variable_value": 9
}
]
},
{
"line_number": 5,
"code_one_line": "console.log(add(5, 4))",
"variables": [
{
"variable_name": "add",
"variable_value": "(a, b) => { return a + b; }"
}
]
}
]
note: I created this above Json manually, following the Vscode debugger.
As you can see from the above example, I want to trace a javascript code step by step on nodejs and store the debugged values in json file.
While searching for this, I came across the njsTrace library, it is great but it works on functions call only. I want the whole step-by-step tracing of code.
Any help would be appreciated.
