# Data formats COLLAB's site is static, so a handful of files carry everything it needs besides the chain: the configuration, the site settings, the deployment record, the deploy bundle, and the cache files the server's prerender job publishes. This page gives each one's schema, an example, its size limits, and which tool writes it and which code reads it. It is for developers who generate, check or consume these files; operators will find what each setting does in [Site settings](site-settings.md) and what the prerender writes when in [Static pages, data files and prices](prerender.md). ## Files at a glance | File | Where | Written by | Read by | Limit | |---|---|---|---|---| | `config.js` | `/config.js`: `shared/config.js` on a server, `web/config.js` on a static host | `tools/write_web_config.py` (the admin service and the installer use it) | `web/js/core/env.js`, `tools/prerender.py`, `collab apply` | | | `site.json` | `shared/site.json` | the admin service (`POST site`), the installer (defaults) | `write_web_config.check_site()` | 65,536 bytes normalized | | `deployments/.json` | `deployments/` in the repository, `shared/deployments/` on a server | `script/Deploy.s.sol`, the admin page's Deploy tab (download) | `write_web_config.py`, `prerender.py`, the admin service | 64 keys | | `collab-protocol.json` | `web/assets/deploy/` | `tools/export_deploy_artifacts.py` | the admin page's Deploy and Check tabs | | | `price.json` | `/data/price.json` | the prerender | `web/js/core/price.js` | 10 KB | | `tokens.json` | `/data/tokens.json` | the prerender (`tools/seo/tokens.py`) | `web/js/descifi/market.js`, `web/js/core/search.js` | 4 MiB | | logos and texts | `/data/logos/.png`, `/data/texts/.txt` | the prerender | `web/js/core/daoprofile.js` | 524,288 and 262,144 bytes | | `network.json` | `/og/network.json` | the prerender (`tools/seo/network.py`) | `web/js/core/directory.js` | 512 KB | | `BUILD.json` | `web/BUILD.json` in a release tree | `tools/version_assets.py` | `tools/shell_html.py`, `server/install.sh` | | On a server the files under `/data/` and `/og/` are written by the user `collab-prerender`; a `/data/` file or `og/network.json` that is not there yet answers 204, and pages then read the chain. Every file the browser reads is checked before use, and anything named by a hash is verified against the hash the chain reports. ## Site configuration `config.js` is the only deployment-specific file of the site. It is a classic script, loaded by every page with `
