@edgedb/generate
: Code generation tools for EdgeDB
The @edgedb/generate
package implements a set of code generation tools that are useful when developing an EdgeDB-backed applications with TypeScript/JavaScript.
Installation
If you're using Deno, you can skip this step.
Install the edgedb
package.
$ npm install edgedb # npm users
$ yarn add edgedb # yarn users
Then install @edgedb/generate
as a dev dependency.
$ npm install @edgedb/generate --save-dev # npm users
$ yarn add @edgedb/generate --dev # yarn users
Run a generator
Run a generator with the following command.
Node.js
$ npx @edgedb/generate <generator> [options]
Deno
$ deno run --allow-all --unstable https://deno.land/x/edgedb/generate.ts <generator> [options]
The value of <generator>
should be one of the following.
queries
: This generator scans your project for*.edgeql
files and generates a file containing a strongly-typed function for each.edgeql-js
: This generator introspects your database schema and generates a query builder.interfaces
: This generator introspects your database schema and generates TypeScript interfaces for each object type.
Third-party generators
✨ If you build a code generator for EdgeDB, ping us or open a PR and we'll list it here! ✨
The edgedb
package exports a set of utilities to introspect the schema and analyze queries. We use this same set of tools to implement the first-party generators.
import {createClient, $} from "edgedb";
const client = createClient();
const types = await $.introspect.types(client);
// Map<string, Type>
const queryData = await $.analyzeQuery(client, `select 2 + 2`);
// {args: string; result: string; ...}
Contributing
If you want to implement a code generator, please open an issue first. This package only contains first-party generators with widespread appeal. From the root directory:
yarn
yarn workspaces run build # build all packages
Navigate into packages/generate
:
Build @edgedb/generate
yarn build
Build without typechecking (uses esbuild
):
yarn build:fast
Run a generator:
npx @edgedb/generate edgeql-js # query builder
npx @edgedb/generate queries # query files
Execute playground.ts
(uses tsx
). Useful for testing things quickly in development:
yarn play
⚠️ All imports from
"edgedb"
resolve to the local build version of the driver inpackages/driver/dist
. This imports the built library, not the so you need to re-runyarn workspace edgedb build
for changes to be reflected in your playground code. Runyarn dev
watcher insidepackages/driver
to rebuild the project anytime you make a change.
Run commands in watch mode. Useful when in development. The following command rebuilds the package and executes the playground whenever a file change is detected.
yarn watch 'yarn build:fast && yarn play`
Run tests. All test:*
scripts are self-contained, in that they execute any prerequisite generation steps before running any tests.
yarn test # runs all tests (listed below)
yarn test:ts
yarn test:esm
yarn test:cjs
yarn test:mts
yarn test:deno
