 # sqliteviz
 
-**Note: This is a work-in-progress project.**
+Sqliteviz is a single-page offline-first PWA for fully client-side visualisation
+of SQLite databases, CSV, JSON or NDJSON files.
+
+With sqliteviz you can:
+
+- run SQL queries against a SQLite database and create [Plotly][11] charts and pivot tables based on the result sets
+- import a CSV/JSON/NDJSON file into a SQLite database and visualize imported data
+- export result set to CSV file
+- manage inquiries and run them against different databases
+- import/export inquiries from/to a JSON file
+- export a modified SQLite database
+- use it offline from your OS application menu like any other desktop app
+
+https://user-images.githubusercontent.com/24638357/128249848-f8fab0f5-9add-46e0-a9c1-dd5085a8623e.mp4
+
+## Quickstart
+
+The latest release of sqliteviz is deployed on [sqliteviz.com/app][6].
+
+## Wiki
+
+For user documentation, check out sqliteviz [documentation][7].
+
+## Motivation
 
-Sqliteviz is a single-page application for fully client-side visualisation of SQLite databases.
 It's a kind of middleground between [Plotly Falcon][1] and [Redash][2].
-It is built on top of [react-chart-editor][3] and [sql.js][4] in [Vue.js][5]. 
 
-## Features
+## Components
 
-1. Ad-hoc and prepared visualisation of a SQLite database using flexibility
-   of SQL and richness of Plotly's `react-chart-editor` 
-2. Visualisation pallete, SQL and chart definitions, kept in local
-   storage with import/export
-3. Integration-side provided pallete
+It is built on top of [react-chart-editor][3], [PivotTable.js][12], [sql.js][4] and [Vue-Codemirror][8] in [Vue.js][5]. CSV parsing is performed with [Papa Parse][9].

+# 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
+2. [FTS3/FTS4][15] -- older virtual table modules for full-text search
+3. [JSON1][16] -- scalar, aggregate and table-valued functions for managing JSON data
+
+SQLite [contribution extensions][17]:
+
+1. [extension-functions][18] -- mathematical and string extension functions for SQL queries.
+
+   Math: `acos`, `asin`, `atan`, `atn2`, `atan2`, `acosh`, `asinh`, `atanh`, `difference`,
+   `degrees`, `radians`, `cos`, `sin`, `tan`, `cot`, `cosh`, `sinh`, `tanh`, `coth`,
+   `exp`, `log`, `log10`, `power`, `sign`, `sqrt`, `square`, `ceil`, `floor`, `pi`.
+
+   String: `replicate`, `charindex`, `leftstr`, `rightstr`, `ltrim`, `rtrim`, `trim`,
+   `replace`, `reverse`, `proper`, `padl`, `padr`, `padc`, `strfilter`.
+
+   Aggregate: `stdev`, `variance`, `mode`, `median`, `lower_quartile`, `upper_quartile`.
+
+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])
+5. `percentile` function ([percentile.c][13])
+6. `decimal`, `decimal_cmp`, `decimal_add`, `decimal_sub` and `decimal_mul` functions
+   ([decimal.c][14])
+
+SQLite 3rd party extensions included:
+
+1. [pivot_vtab][5] -- a pivot virtual table
+2. `pearson` correlation coefficient function extension from [sqlean][21]
+   (which is part of [squib][20])
+3. [sqlitelua][22] -- a virtual table `luafunctions` which allows to define custom scalar,
+   aggregate and table-valued functions in Lua
+
+To ease the step to have working clone locally, the build is committed into
+the repository.
+
+Examples of queries involving these extensions can be found in the test suite in
+[sqliteExtensions.spec.js][19].
+
+## 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 read and write SQL queries, run from `make.sh` script. If
+the script has permission to `nice` processes and [Procpath][1] is installed,
+e.g. it is run with `sudo -E env PATH=$PATH ./make.sh`, it'll `renice` all
+processes running inside the benchmark containers. It can also serve as a smoke
+test (e.g. for memory leaks).
+
+The benchmark operates on a set of SQLite WebAssembly builds expected in
+`lib/build-$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 produces the following per each build:
+
+- `build-$NAME-result.json`
+- `build-$NAME.sqlite` (if Procpath is installed)
+- `build-$NAME.svg` (if Procpath is installed)
+
+These files can be analysed using `result-analysis.ipynb` Jupyter notebook.
+The SVG is a chart with CPU and RSS usage of each test container (i.e. Chromium
+run, then Firefox run per container).
