API
eval
Evaluates JavaScript code represented as a string.
public mixed function eval(string $script, int $flags = V8Js::FLAG_NONE, int $timeLimit = 0, int $memoryLimit = 0)
Almost the same as V8Js::executeString
except $identifier
argument.
public mixed function V8Js::executeString(string $script, string $identifier = '', int $flags = V8Js::FLAG_NONE, int $timeLimit = 0, int $memoryLimit = 0)
Usage:
$context->eval('1+1'); // 2
load
Evaluates JavaScript code represented from a file.
public mixed function load(string $module, int $flags = V8Js::FLAG_NONE, int $timeLimit = 0, int $memoryLimit = 0)
$context->load('./foo.js'); // equals $str = $context->getLoader()->loadModule('./foo.js'); $context->eval($str);
require
CommonJS module support to require external code.
public mixed function require(string $module, string|array $identifier = null)
Usage:
$yaml = $context->require('js-yaml'); $yaml->load('a: b'); // ['a' => 'b']
String identifier
$yaml = $context->require('js-yaml', 'jsyaml'); // equals $context->eval("var jsyaml = require('js-yaml'); jsyaml;"); // usage $yaml->load('a: b'); // ['a' => 'b'] $context->eval(sprintf('jsyaml.dump(%s)', json_encode(['a' => 'b']))); // 'a: b'
Array identifier
$context->require('js-yaml', ['load', 'dump']); // equals $context->eval("var {load, dump} = require('js-yaml').load;"); $context->eval("load('a: b')"); // ['a' => 'b'] $context->eval(sprintf('dump(%s)', json_encode(['a' => 'b']))); // 'a: b' $context->require('js-yaml', ['load' => 'yamlLoad']); // equals $context->eval("var yamlLoad = require('js-yaml').load;"); // es6: import {load as yamlLoad} from 'js-yaml' $context->eval("yamlLoad('a: b')"); // ['a' => 'b']
set
Assign a property to make it accessible to the javascript context.
public Context function set(string $key, mixed $value, $global = false)
Usage:
$context->set('foo', 'bar'); $context->eval('PHP.foo'); // bar $context->eval('foo'); // error undefined $context->set('bar', 'baz', true); $context->eval('PHP.bar'); // baz $context->eval('bar'); // baz $context->set('process', [ 'env' => [ 'NODE_ENV' => 'production', ], ], true); $context->eval('process.env.NODE_ENV'); // production
