The Compiler
object:
const { Compiler } = require('@locker/compiler');
// Compile code using `Compiler.compile(input, options)`. The function returns
// an object of `{ code, map, meta }`.
Compiler.compile(input, {
// The name of the component to compile.
componentName: undefined,
// The absolute filename of `input` required for source maps.
filename: undefined,
// Specify remapping blue dynamic imports into the red Realm.
// Valid option values are `true`, `false`, or an options object.
// - Use `true` as shorthand for an options object of
// `{ strictSpecifier: true }`.
// - Use `false` disable remapping dynamic import.
remapDynamicImport: {
// Specify whether dynamic imports should be restricted to string
// literal source specifiers, e.g.
// import('./a.js') // allowed
// import(a) // not allowed
// import(`${a}`) // not allowed
strictSpecifier: true,
},
// The key of the sandbox to evaluate source text in.
// For more details see https://www.npmjs.com/package/@locker/sandbox#usage.
sandboxKey: 'sandbox',
// Specify whether to generate inline source maps.
sourceMap: false,
//
// *** ADVANCED ***
//
// Specify a map to use as the memoized compilation cache.
// See https://en.wikipedia.org/wiki/Memoization for more context.
compilationCache: new Map(),
// Specify the name of the sandbox evaluation context identifier.
sandboxEvalContext: '$lockerEvalContext$',
// Specify the name of the sandbox evaluation helpers identifier.
sandboxEvalHelpers: '$lockerEvalHelpers$',
// Specify the name of the sandbox package identifier.
sandboxPackage: '@locker/sandbox',
// Specify the name of the sandbox specifier.
sandboxSpecifier: 'evaluateInSandbox',
});
// Create a new normalized fully populated `Compiler.compile()` options object
// using `Compiler.createOptions(providedOptions)`.
Compiler.createOptions({
sandboxKey: 'anotherKey',
});
// Inspect the default options of `Compiler.compile()` using `Compiler.defaultOptions`.
console.log(Compiler.defaultOptions);
The Parser
object:
const { Parser } = require('@locker/compiler');
// Create a `Parser` instance using `Parse.create(input, options)`.
const parser = Parse.create(input, {
// Produce an abstract syntax tree (AST) for use with the custom parser API
// of Prettier. For more details see https://prettier.io/docs/en/api.html#custom-parser-api.
prettier: true,
});
// The `parser.parse()` method returns the generated AST object.
let ast = parser.parse();
// Create an AST object representation of parsed `input` without an intermediate
// `parser` instance using `Parser.parse(input, options)`.
ast = Parser.parse(input, options);
// Create a new normalized fully populated `Parser.parse()` options object
// using `Parser.createOptions(providedOptions)`.
Parser.createOptions({
prettier: true,
});
// Inspect the default options of `Parser.create()` using `Parser.defaultOptions`.
console.log(Parser.defaultOptions);
