sqliteBuilder: Opinionated safe(r) query builder using tagged templates import { Statement } from "https://esm.town/v/postpostscript/sqliteBuilder"; const unsafeId = "1234 or TRUE" console.log(Statement` SELECT * FROM table WHERE id = ${unsafeId} ${Statement`AND other_`} `) // StatementInstance { // sql: "\nSELECT *\nFROM table\nWHERE id = ?\nAND otherCondition\n", // args: [ "1234 or TRUE" ], // log: false // } const results = await Statement`SELECT ...`.execute() // [ { key: "value", anotherKey: "anotherValue" }, ... ] Or you can pass it directly to @std/sqlite.execute : import { sqlite } from "https://esm.town/v/std/sqlite" await sqlite.execute(Statement`Select ...`) You can combine multiple statements using Statement.prototype.combineWith : Statement`...`.combineWith(Statement`...`, " AND ") [ Statement`fieldA`, Statement`fieldB`, Statement`fieldC`, ].reduce((a, b) => a.combineWith(b, ", "))

Query All Public Vals Example: val town leaderboard import { zip } from "https://esm.town/v/pomdtr/sql"; import { db } from "https://esm.town/v/sqlite/db"; const res = await db.execute("SELECT author_username, COUNT(*) AS val_count FROM vals GROUP BY author_username ORDER BY 2 DESC LIMIT 10"); console.table(zip(res));

sqliteUniverse: make queries against multiple vals or endpoints at the same time! Example: @postpostscript/sqliteUniverseExample Todo [ ] tests‼️ [ ] update to support following syntax: SELECT * FROM "@example/endpoint".someTable or SELECT * FROM "@example/endpoint:::someTable"

SQLite Table Export Utils This allows for a val.town-hosted SQLite table to be exported as: JSON ( Record<string, unknown>[] ) Arrow IPC ( Uint8Array ) TODO: Others? This can then be used by a HTTP endpoint, like so: import { exportSQLiteTable, SQLiteTableExportFormat } from "https://esm.town/v/rlesser/sqliteTableExportUtils"; export default async function(req: Request): Promise<Response> { const tableName = new URL(req.url).searchParams.get("table"); if (!tableName) { return new Response("Table name is required", { status: 400 }); } const format = (new URL(req.url).searchParams.get("format") || "arrowIPC") as SQLiteTableExportFormat; const data = await exportSQLiteTable(tableName, format); if (data instanceof Uint8Array) { return new Response(data, { headers: { "Content-Type": "application/octet-stream" }, }); } else { return Response.json(data); } } TODO Specify limit and offset of export, for pagination Smart assessment of if the export is going to be over the val.town limit of 10MB, adjust to paginated of so. Support other export formats. PRs welcome!
