|
||
|
|
|
||
|
|
NAN provides `v8::Script` helpers as the API has changed over the supported versions of V8.

### Nan::CompileScript()
|
||
|
|
|
||
|
|
A wrapper around [`v8::ScriptCompiler::Compile()`](https://v8docs.nodesource.com/node-8.16/da/da5/classv8_1_1_script_compiler.html#a93f5072a0db55d881b969e9fc98e564b).
|
||
|
|
|
||
|
|
Note that `Nan::BoundScript` is an alias for `v8::Script`.
|
||
|
|
|
||
|
|
Signature:
|
||
|
|
|
||
|
|
```c++
|
||
|
|
Nan::MaybeLocal<Nan::BoundScript> Nan::CompileScript(
|
||
|
|
v8::Local<v8::String> s,
|
||
|
|
const v8::ScriptOrigin& origin);
|
||
|
|
Nan::MaybeLocal<Nan::BoundScript> Nan::CompileScript(v8::Local<v8::String> s);
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
<a name="api_nan_run_script"></a>
|
||
|
|
### Nan::RunScript()
|
||
|
|
|
||
|
|
Calls `script->Run()` or `script->BindToCurrentContext()->Run(Nan::GetCurrentContext())`.
|
||
|
|
|
||
|
|
Note that `Nan::BoundScript` is an alias for `v8::Script` and `Nan::UnboundScript` is an alias for `v8::UnboundScript` where available and `v8::Script` on older versions of V8.
|
||
|
|
|
||
|
|
Signature:
|
||
|
|
|
||
|
|
```c++
|
||
|
|
Nan::MaybeLocal<v8::Value> Nan::RunScript(v8::Local<Nan::UnboundScript> script)
|
||
|
|
Nan::MaybeLocal<v8::Value> Nan::RunScript(v8::Local<Nan::BoundScript> script)
|
||
|
|
```

|
<a name="api_nan_script_origin"></a>
|
||
|
|
### Nan::ScriptOrigin
|
||
|
|
|
||
|
|
A class transparently extending [`v8::ScriptOrigin`](https://v8docs.nodesource.com/node-16.0/db/d84/classv8_1_1_script_origin.html#pub-methods)
|
||
|
|
to provide backwards compatibility. Only the listed methods are guaranteed to
|
||
|
|
be available on all versions of Node.
|
||
|
|
|
||
|
|
Declaration:
|
||
|
|
|
||
|
|
```c++
|
||
|
|
class Nan::ScriptOrigin : public v8::ScriptOrigin {
|
||
|
|
public:
|
||
|
|
ScriptOrigin(v8::Local<v8::Value> name, v8::Local<v8::Integer> line = v8::Local<v8::Integer>(), v8::Local<v8::Integer> column = v8::Local<v8::Integer>())
|
||
|
|
v8::Local<v8::Value> ResourceName() const;
|
||
|
|
v8::Local<v8::Integer> ResourceLineOffset() const;
|
||
|
|
v8::Local<v8::Integer> ResourceColumnOffset() const;
|
||
|
|
}
|
||
|
|
```
