Package Exports
- estraverse
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (estraverse) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Estraverse 
Estraverse (estraverse) is ECMAScript traversal functions from esmangle project.
Example Usage
The following code will output all variables declared at the root of a file.
estraverse.traverse(ast, {
enter: function (node, parent) {
if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
return estraverse.VisitorOption.Skip;
},
leave: function (node, parent) {
if (node.type == 'VariableDeclarator')
console.log(node.id.name);
}
});We can use this.skip and this.break functions instead of using Skip and Break.
estraverse.traverse(ast, {
enter: function (node) {
this.break();
}
});And estraverse provides estraverse.replace function. When returning node from enter/leave, current node is replaced with it.
result = estraverse.replace(tree, {
enter: function (node) {
// Replace it with replaced.
if (node.type === 'Literal')
return replaced;
}
});License
