 Sqliteviz is a single-page offline-first PWA for fully client-side visualisation of SQLite databases or CSV files.

 With sqliteviz you can:
- run SQL queries against a SQLite database and create [Plotly][11] charts based on the result sets
+- run SQL queries against a SQLite database and create [Plotly][11] charts and pivot tables based on the result sets
 - import a CSV file into a SQLite database and visualize imported data
- manage queries and chart settings and run them against different databases
- import/export queries and chart settings to/from a JSON file
+- manage inquiries and run them against different databases
+- import/export inquiries to/from a JSON file
 - export a modified SQLite database
 - use it offline from your OS application menu like any other desktop app

+# SQLite WebAssembly build
+
+This directory contains Docker-based build script, `make.sh`, that builds
+a custom version of [sql.js][1]. It allows sqliteviz to have more recent
+version of SQLite build with a number of useful extensions.
+
+`Makefile` from [sql.js][1] is rewritten as more comprehensible `configure.py`
+ and `build.py` Python scripts that run in `emscripten/emsdk` Docker container.
+
+## Extension
+
+SQLite [amalgamation][2] extensions included:
+
+1. [FTS5][4] -- virtual table module that provides full-text search
+   functionality
+
+SQLite [miscellaneous extensions][3] included:
+
+1. `generate_series` table-valued [series function][6] ([series.c][7])
+2. `transitive_closure` virtual table for
+   [Querying Tree Structures in SQLite][11] ([closure.c][8])
+3. `uuid`, `uuid_str` and `uuid_blob` RFC-4122 UUID functions ([uuid.c][9])
+4. `regexp` (hence `REGEXP` operator) and `regexpi` functions ([regexp.c][10])
+
+SQLite 3rd party extensions included:
+
+1. [pivot_vtab][5] -- a pivot virtual table
+
+To ease the step to have working clone locally, the build is committed into
+the repository.
+
+## Build method
+
+Basically it's extended amalgamation and `SQLITE_EXTRA_INIT` concisely
+described in [this message from SQLite Forum][12]:
+
+> Simply append it to the end of the amalgamation file. The real problem is
+> how you get the init function called. The easiest way (to me at any rate) is
+> to append a function (after the extensions you want to add are all appended)
+> that adds the init function for each extension to the auto extension list
+> for new connections, and set the pre-processor symbol SQLITE_EXTRA_INIT to
+> the name of this function. [...]
+>
+> An example `SQLITE_EXTRA_INIT` function looks like this:
+>
+> ```
+> int core_init(const char* dummy)
+> {
+>    int nErr = 0;
+>
+>    nErr += sqlite3_auto_extension((void*)sqlite3_autobusy_init);
+>    nErr += sqlite3_auto_extension((void*)sqlite3_ipaddress_init);
+>
+>    return nErr ? SQLITE_ERROR : SQLITE_OK;
+> }
+> ```
+>
+> so you would then define `SQLITE_EXTRA_INIT=core_init` when compiling the
+> amalgamation code and the extensions would thereafter be automatically
+> initialized on each connection.

+# SQLite WebAssembly build micro-benchmark
+
+This directory contains a micro-benchmark for evaluating SQLite
+WebAssembly builds performance on typical SQL queries, run from
+`make.sh` script. It can also serve as a smoke test.
+
+The benchmark operates on a set of SQLite WebAssembly builds expected
+in `lib/build-$NAME` directories each containing `sql-wasm.js` and
+`sql-wasm.wasm`. Then it creates a Docker image for each, and runs
+the benchmark in Firefox and Chromium using Karma in the container.
+
+After successful run, the benchmark result of each build is contained
+in `build-$NAME-result.json`. The JSON result files can be analysed
+using `result-analysis.ipynb` Jupyter notebook.
