|
|
|

### 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; |
|
} |
|
```
