For additional commentary on this release, see [Datasette 0.54, the annotated release notes](https://simonwillison.net/2021/Jan/25/datasette/). ### The _internal database As part of ongoing work to help Datasette handle much larger numbers of connected databases and tables (see [Datasette Library](https://github.com/simonw/datasette/issues/417)) Datasette now maintains an in-memory SQLite database with details of all of the attached databases, tables, columns, indexes and foreign keys. ([#1150](https://github.com/simonw/datasette/issues/1150)) This will support future improvements such as a searchable, paginated homepage of all available tables. You can explore an example of this database by [signing in as root](https://latest.datasette.io/login-as-root) to the `latest.datasette.io` demo instance and then navigating to [latest.datasette.io/_internal](https://latest.datasette.io/_internal). Plugins can use these tables to introspect attached data in an efficient way. Plugin authors should note that this is not yet considered a stable interface, so any plugins that use this may need to make changes prior to Datasette 1.0 if the `_internal` table schemas change. ### Named in-memory database support As part of the work building the `_internal` database, Datasette now supports named in-memory databases that can be shared across multiple connections. This allows plugins to create in-memory databases which will persist data for the lifetime of the Datasette server process. ([#1151](https://github.com/simonw/datasette/issues/1151)) The new `memory_name=` parameter to the [Database class](https://docs.datasette.io/en/stable/internals.html#internals-database) can be used to create named, shared in-memory databases. ### JavaScript modules [JavaScript modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) were introduced in ECMAScript 2015 and provide native browser support for the `import` and `export` keywords. To use modules, JavaScript needs to be included in `
