Parser, Tree class roadmap

[MajorLift]

1. Parser

A. Expand Import Statement support

a) Static Imports

• [ ] For static import statements with namespace or default specifiers, only add members that are used in the document.

import foo from "mod.js"
import * as foo from "mod.js"

• [ ] Module imports for side effects only

import '/modules/my-module.js';
import 'http:example.com\pears.js';

b) Require Statements

• [ ] Support namespaces and member expressions

const foo = require("./module"); ... ; <foo.component />;

• [ ] Support invocations and method/member calls

const foo = require("./module")();
const foo = require("./module").method(arg);

c) Dynamic imports

• [ ] Support AwaitExpression

const foo = await import("./module")

• [ ] Support Promise.resolve()

const foo = Promise.resolve(import("./module"))

• [ ] Support .then() chains

import("./module").then(mod => mod.loadPage())

• [ ] Support non-literal specifiers in module name

import(`/modules/module-${index}.js`)

B. Implement Export Statement parser

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/export#syntax

C. Support Barrel files

• [ ] 1) Recognize barrel files
• [ ] 2) Parse export statements in barrel file
• [ ] 3) Parse export statements for components in each barrel file entry.

D. Support more path types

• [ ] https://github.com/oslabs-beta/sapling/issues/108
• [ ] Support TypeScript path aliases
• [ ] #9

E. Increase Babel type guard coverage

• [ ] .getJSXChildren(), .getJSXProps(), .checkForRedux() methods
• [ ] https://github.com/oslabs-beta/sapling/issues/107
• [ ] Nested Import CallExpression in ArrowFunctionExpression body.

const foo = React.lazy(() => import('./module'));

2. Tree

• [ ] Consolidate Tree and Node data class/interfaces for parser, serialized workspace cache, and webview.
• [ ] Encapsulation for class members
