XML to Flow Converter

Generate Flow type aliases from XML samples when your JavaScript codebase still relies on Flow for typed XML integrations instead of moving the project to TypeScript.

How to use

  1. Paste a representative XML document that matches the nested elements and repeated nodes your app actually parses.
  2. Review the generated Flow aliases for object nesting, list-like XML structures, and optional properties inferred from the parsed XML shape.
  3. Copy the aliases into your Flow-checked module and refine naming or helper wrappers that fit your existing XML parsing layer.

Benefits

  • Brings XML-derived payloads into Flow-checked JavaScript projects without forcing a TypeScript rewrite.
  • Turns repeated XML nodes into reusable alias shapes that are easier to maintain than ad hoc object comments.
  • Keeps typed XML integration work in the same browser-side generation workflow as the JSON Flow route.

Best use cases

  • Legacy JavaScript apps consuming XML APIs while still using Flow for static checking.
  • Migration-period codebases that need typed XML contracts before a broader tooling shift.
  • Teams generating Flow aliases for parser output shared across service and UI layers.

XML Flow tips

  • Use realistic XML samples so repeated nodes and optional elements are inferred in a way that matches production data.
  • Compare the generated alias names with your parser output shape before wiring them into a shared client module.
  • Switch to XML-to-TypeScript when the surrounding project ecosystem or package consumers have standardized on TS instead of Flow.

Implementation tips

  • Choose this route when your current toolchain already uses Flow for static checks.
  • Review optional properties against real payload variability before treating generated aliases as stable contracts.
  • Switch to TypeScript routes instead when downstream consumers expect TS-native tooling, declaration emit, or schema inference.

Sample XML

<user>
  <id>101</id>
  <name>Ada Lovelace</name>
  <active>true</active>
  <roles>
    <role>admin</role>
    <role>editor</role>
  </roles>
  <profile>
    <email>ada@example.com</email>
    <score>9.8</score>
  </profile>
</user>

Sample output

export type UserModel = {
  id: number,
  name: string,
  active: boolean,
  roles: Array<string>,
  profile: Profile,
};

export type Profile = {
  email: string,
  score: number,
};

FAQ

Why choose the XML Flow route instead of XML to TypeScript?

Choose XML to Flow when the current JavaScript project already uses Flow and you need typed XML contracts without changing the checker. Choose XML to TypeScript when the broader app or shared packages are TypeScript-first.

Can the XML Flow route handle nested and repeated XML nodes?

Yes. Nested XML elements become child Flow aliases, and repeated nodes are inferred into array-like field types based on the parsed XML structure.
