Overview

follow file imports using pabel ast parsing to find the file where an imported keyword was exported from (and is defined in).

Installation

$ npm install @component-controls/follow-imports --save-dev

API

properties

| Name | Type | Parent | Default | Description | | -------------------------------- | ------------------------------------------- | --------------- | ---------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | allowImportExportEverywhere | boolean | ParserOptions | | By default, import and export declarations can only appear at a program's top level. Setting this option to true allows them anywhere where a statement is allowed. | | allowAwaitOutsideFunction | boolean | ParserOptions | | By default, await use is not allowed outside of an async function. Set this to true to accept such code. | | allowReturnOutsideFunction | boolean | ParserOptions | | By default, a return statement at the top level raises an error. Set this to true to accept such code. | | allowSuperOutsideMethod | boolean | ParserOptions | | | | allowUndeclaredExports | boolean | ParserOptions | | By default, exported identifiers must refer to a declared variable. Set this to true to allow export statements to reference undeclared variables. | | attachComment | boolean | ParserOptions | | By default, Babel attaches comments to adjacent AST nodes. When this option is set to false, comments are not attached. It can provide up to 30% performance improvement when the input code has many comments. | | errorRecovery | boolean | ParserOptions | | By default, Babel always throws an error when it finds some invalid code. When this option is set to true, it will store the parsing error and try to continue parsing the invalid input file. | | sourceType | "script" | "module" | "unambiguous" | ParserOptions | "module" | Indicate the mode the code should be parsed in. Can be one of "script", "module", or "unambiguous". Defaults to "script". "unambiguous" will make @babel/parser attempt to guess, based on the presence of ES6 import or export statements. Files with ES6 imports and exports are considered "module" and are otherwise "script". | | sourceFilename | string | ParserOptions | | Correlate output AST nodes with their source filename. Useful when generating code and source maps from the ASTs of multiple input files. | | startLine | number | ParserOptions | | By default, the first line of code parsed is treated as line 1. You can provide a line number to alternatively start with. Useful for integration with other source tools. | | plugins | ParserPlugin[] | ParserOptions | | Array containing the plugins that you want to enable. | | strictMode | boolean | ParserOptions | | Should the parser work in strict mode. Defaults to true if sourceType === 'module'. Otherwise, false. | | ranges | boolean | ParserOptions | | Adds a ranges property to each node: [node.start, node.end] | | tokens | boolean | ParserOptions | | Adds all parsed tokens to a tokens property on the File node. | | createParenthesizedExpressions | boolean | ParserOptions | | By default, the parser adds information about parentheses by setting extra.parenthesized to true as needed. When this option is true the parser creates ParenthesizedExpression AST nodes instead of using the extra property. |

(default to 'node_modules') | | preserveSymlinks | boolean | Opts | | if true, doesn't resolve basedir to real path before resolving. This is the way Node resolves dependencies when executed with the --preserve-symlinks flag. Note: this property is currently true by default but it will be changed to false in the next major version because Node's resolution algorithm does not preserve symlinks by default. |
