load json files in code example

Example 1: python json load file

import json

# with json load  (file)
info = open('data.json',)
res = json.load(info)
print(res)
print("Datatype after deserialization : " + str(type(res)))
#>>> {'name': 'Dave', 'City': 'NY'}
#>>> Datatype of the serialized JSON data : <class 'dict'>

Example 2: read json data from file

// consider your file data is something like json string but aving parse issue 
//that means some additional char is there 
fs.readFile(ROLES_FILE, "utf8", (err, data) => {
      if (err) {
        res.status(403).json({});
      }
      const [localScope, action] = scope.split(".");
      const mapper = JSON.parse(data.toString("utf8").replace(/^\uFEFF/, ""));
      const isAllowed = checkRole(mapper, localScope, action, role);
      if (isAllowed) {
        next();
      } else {
        res.status(403).json({});
      }
