odbc vs xfun
A side-by-side editorial comparison of odbc and xfun — release velocity, themes, recent moves, and the top alternatives to consider.
odbc vs xfun: at a glance
What is odbc?
odbc keeps turning into an authentication broker with a database driver attached.
odbc is DBI's ODBC backend, and the releases in view are dominated by three vendors. Databricks, Snowflake and Redshift each got a dedicated connection helper, and the work since has been almost entirely about credentials: OAuth, viewer-based identity on Posit Connect, service principals, workload identity federation, private keys passed from memory. The plain driver work — DATETIMEOFFSET on SQL Server, DB2 XML, Oracle date writes, an interrupt that no longer crashes — runs underneath in a steady stream of point releases.
What is xfun?
Yihui's utility grab-bag is quietly growing a web server and a headless browser.
xfun is the shared utility layer under knitr, rmarkdown, bookdown and litedown, and its recent releases cluster in three places: the record() function that captures code output for litedown, a local app-serving stack built on R's internal httpd, and a headless-browser toolkit. Version 0.58 replaced direct httpd routing with a proxy and added serve_dir() and random_port(); 0.55 added browser_print() and 0.60 added browser_dom(), which runs JavaScript on a page and returns the rendered DOM.

odbc keeps turning into an authentication broker with a database driver attached.
◆ Current state
odbc is DBI's ODBC backend, and the releases in view are dominated by three vendors. Databricks, Snowflake and Redshift each got a dedicated connection helper, and the work since has been almost entirely about credentials: OAuth, viewer-based identity on Posit Connect, service principals, workload identity federation, private keys passed from memory. The plain driver work — DATETIMEOFFSET on SQL Server, DB2 XML, Oracle date writes, an interrupt that no longer crashes — runs underneath in a steady stream of point releases.
◆ Where it's heading
The centre of the package has moved from talking to a database to proving who you are to a warehouse. Version 1.7.0 makes that explicit by handing Snowflake connection resolution to the snowflakeauth package so odbc reads the vendor's own connections.toml rather than defining its own parameter set. That is a pattern worth watching: as each warehouse standardises its config across CLI, Python and R, odbc's job shifts from inventing an interface to conforming to one.
◆ Prediction
Expect Databricks to get the same treatment Snowflake just received — configuration resolved from the vendor's own config files rather than from odbc arguments — and expect the deprecated odbcConnection* functions to be removed outright.
xfun
0.0DEVOPS
Yihui's utility grab-bag is quietly growing a web server and a headless browser.
◆ Current state
xfun is the shared utility layer under knitr, rmarkdown, bookdown and litedown, and its recent releases cluster in three places: the record() function that captures code output for litedown, a local app-serving stack built on R's internal httpd, and a headless-browser toolkit. Version 0.58 replaced direct httpd routing with a proxy and added serve_dir() and random_port(); 0.55 added browser_print() and 0.60 added browser_dom(), which runs JavaScript on a page and returns the rendered DOM.
◆ Where it's heading
The package is accreting the infrastructure Yihui's publishing tools need rather than staying a pile of small helpers. Serving directories, allocating ports, proxying the help server, driving a headless browser and printing to PDF are all pieces of one pipeline: render R output to HTML, then get it onto a screen or into a static file without a heavyweight dependency. The rest of the release stream is release-automation tooling for the author's own CRAN workflow and a long tail of parser bug fixes in taml_load().
◆ Prediction
Expect the browser functions to consolidate into a documented interface used directly by litedown, and expect cache_rds() to be fully retired in favour of cache_exec() now that it is no longer recommended.
