The v8 module exposes APIs that are specific to the version of V8 built into the Node.js binary.
Example:
Output:
{ total_heap_size: 6537216,
total_heap_size_executable: 1048576,
total_physical_size: 6537216,
total_available_size: 1520717240,
used_heap_size: 4199600,
heap_size_limit: 1526909922,
malloced_memory: 8192,
peak_malloced_memory: 406408,
does_zap_garbage: 0 }
The Complete list of V8 are listed below:
V8 Module APIs
V8 Module APIs | Description |
|---|---|
| cachedDataVersionTag() | Get the version tag derived from the v8 version. |
| getHeapSpaceStatistics() | Get statistics about heap space derived from the v8 version. |
| getHeapStatistics() | Get statistics about heap derived from the v8 version. |
Serialization API
Serialization API | Description |
|---|---|
| v8.serialize() | Serialize any type of data into a buffer using default serializer. |
| v8.deserialize() | Deserialize a buffered data into JS value using default deserializer. |
Class: v8.Serializer
Class: v8.Serializer Methods | Description |
|---|---|
| writeHeader() | Write out a header, that contains the serialization format version. |
| writeValue() | Write the serialized data of JS value to the internal buffer. |
| releaseBuffer() | Get content of the internal buffer. |
| writeUint32() | Write the raw 32-bit integer value to the internal buffer.. |
| writeUint64() | Write a raw 64-bit integer value to the internal buffer by splitting into high and low 32-bit integers. |
| writeDouble() | Write a JS number value to the internal buffer. For use inside of custom serializer._writeHostObject(). |
| writeRawBytes() | Write a raw buffer data to the internal buffer. |
Class: v8.Deserializer
Class: v8.Deserializer Methods | Description |
|---|---|
| readHeader() | Read the header and validate it, to ensure that contains a valid serialization format version. |
| readValue() | Read the JS value from serialized data as present in a buffer. |
| readUint32() | Read a raw 32-bit unsigned integer value from the buffer. |
| readUint64() | Read a raw 64-bit unsigned integer value from the buffer as an array of 32-bit integers, higher and lower 32-bits separated. |
| readRawBytes() | Read a raw buffer data from deserializer’s internal buffer of the given length. |
