_I meant at what point(s) in the pipleline from
(driver)-[:EXECUTES_STATEMENTS)->(apachAge) are we dependent on
parsing/serialization, and thus need to plug in custom replacer and reviver ?_
Pretty much any case that depends upon communicating JSON data over the
wire, such as between client and server.
I've solved the serialization issue using these custom replacer/reviver
functions for JSON.parse and JSON.stringify.
```
const NULL = 'n';
const BIGINT = 'i';
const STRING = 's';
const BOOLEAN = 'b';
const NUMBER = 'f';
/**
* BigInt compatible JSON.stringify replacer function
*/
export function json_replacer(key, value) {
const type = typeof value;
if (type === "string") {
return `${STRING}:${value}`;
} else if (type === "number") {
return `${NUMBER}:${value}`;
} else if (type === "bigint") {
return `${BIGINT}:${value}`;
} else if (type === "boolean") {
return `${BOOLEAN}:${value}`;
} else if (value === null) {
return `${NULL}:${value}`;
} else if (type === "object") {
return value;
} else {
throw new TypeError();
}
}
/**
* BitInt compatible JSON.parse reviver function
*/
export function json_reviver(key, value) {
const type = typeof value;
if (type === "string") {
const t = String(value).substring(0, 1);
const v = String(value).substring(2);
if (t === STRING) {
return String(v);
} else if (t === NUMBER) {
return Number(v);
} else if (t === BIGINT) {
return BigInt(v);
} else if (t === BOOLEAN) {
return Boolean(v);
} else if (t === NULL) {
return null;
} else {
throw new TypeError();
}
} else if (type === "object") {
return value;
} else {
throw new TypeError();
}
};
```
