# Architecture
|
|
|
|
Network Tools is a static React/Vite application wrapped in the shared Toolbox shell. `Workbench.tsx` owns only transient view state and delegates to small pure modules:
|
|
|
|
- `network/url.ts` resolves and decomposes URLs with the platform `URL` parser and returns a password-redacted display value.
|
|
- `network/vlsm.ts` parses bounded `name,hosts` requirements, sorts largest-first and allocates aligned IPv4 blocks atomically inside one parsed base CIDR.
|
|
- `network/dns.ts` constructs one bounded zone-file record and inertly parses complete pasted zone text. The zone parser joins bounded parenthesized records, honours local `$ORIGIN`/`$TTL`, validates common RDATA and retains unsupported record types as clearly marked syntax-only data. It rejects rather than follows external/generative directives such as `$INCLUDE`.
|
|
- `network/http.ts` parses a pasted header block, analyses a deployed CSP plus baseline response-header protections, and constructs an explicit CSP from source tokens.
|
|
- `network/mime.ts` is a project-authored offline reference table.
|
|
|
|
All operations are short, bounded and synchronous, so the app does not create a worker. VLSM is capped at 1,024 requirements; zone text at 2 MiB/50,000 physical lines/20,000 records; headers at 256 KiB/2,048 fields and CSP at 128 KiB. There is no server API, persistence layer or runtime lookup. Relative entry and asset URLs keep the production build relocatable below a nested portal path.
