Topic 1: tagged-template

Concept

soda-gql supports tagged template syntax for writing GraphQL fragments and operations. Only gql is exported from the generated runtime:

import { gql } from "<outdir-path>"; // e.g. "@/graphql-system"
// Fragment with tagged template
const userFragment = gql.default(({ fragment }) =>
  fragment("UserFields", "User")`{
    id
    name
    email
  }`(),
);
// Operation with tagged template
const getUserQuery = gql.default(({ query }) =>
  query("GetUser")`($id: ID!) {
    user(id: $id) {
      id
      name
    }
  }`(),
);

When to Use Tagged Template vs Callback Builder

Decision Tree:

1. Fragment definition:

• ✅ Use tagged template: Simple field selection, no aliases
• ❌ Use callback builder: Field aliases needed

1. Fragment spreading (Fragment → Fragment):

• ✅ Use tagged template interpolation: ...${otherFragment}

1. Operation definition:

• ✅ Use tagged template: No fragment spreads via .spread(), no aliases, no $colocate
• ❌ Use callback builder: Has fragment spreads via .spread(), aliases, or $colocate

1. Special features:

• Metadata callbacks with variable access → callback builder only
• Operations with .spread() → callback builder only

Key Constraint

Both tagged templates reject interpolation with values:

• fragment("Name", "Type")\${value}\`` → ❌ Throws error
• query("Name")\{ field(id: ${id}) }\`` → ❌ Throws error

The only valid interpolation is fragment-to-fragment spreading: fragment("Name", "Type")\...${otherFragment} ...\``.

Operations with fragment spreads MUST use callback builder syntax with .spread() instead of tagged template interpolation.

Documentation References

• Callback-only features: playgrounds/vite-react/src/graphql/callback-builder-features.ts
• Fragment patterns: playgrounds/vite-react/src/graphql/fragment-spread-patterns.md

Code Examples

Tagged template fragment:

// playgrounds/vite-react/src/graphql/fragments.ts
const userFields = gql.default(({ fragment }) =>
  fragment("UserFields", "User")`{
    id
    name
    email
    createdAt
  }`(),
);

Tagged template operation (no spreads):

// playgrounds/vite-react/src/graphql/operations.ts
const simpleQuery = gql.default(({ query }) =>
  query("GetUsers")`{
    users {
      id
      name
    }
  }`(),
);

Callback builder operation (with spreads):

// playgrounds/vite-react/src/graphql/callback-builder-features.ts
const userQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: {
      ...$var("id").ID("!"),
    },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...userFields.spread(),
      })),
    }),
  }),
);

Common Patterns

✅ Simple fragment with tagged template:

const fields = gql.default(({ fragment }) =>
  fragment("UserBasic", "User")`{
    id
    name
    email
  }`(),
);

✅ Fragment spreading another fragment (tagged template):

const extendedFields = gql.default(({ fragment }) =>
  fragment("ExtendedUser", "User")`{
    ...${userFields}
    createdAt
    updatedAt
  }`(),
);

❌ Operation with fragment spread (WRONG - tagged template):

// This will FAIL - cannot use tagged template interpolation for fragment spreads in operations
const badQuery = gql.default(({ query }) =>
  query("BadQuery")`{
    user {
      ${userFields}
    }
  }`(),
);

✅ Operation with fragment spread (CORRECT - callback builder):

const userQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: { ...$var("id").ID("!") },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...userFields.spread(),
      })),
    }),
  }),
);

Topic 2: fragment

Concept

Fragments define reusable field selections with type safety. They can be spread into operations or composed into other fragments.

Fragment Types

1. Tagged template fragment — Simple field selection
2. Callback builder fragment — Aliases, nested spreads, metadata
3. Fragment spreading — Composing fragments together

Variable Declaration Pattern

"Fragments declare requirements; operations declare contract"

• Fragments can declare variables they need in the GraphQL definition
• Operations must explicitly declare ALL variables, including fragment requirements
• No auto-merge: operation variables are the source of truth

Documentation References

• Spread patterns: playgrounds/vite-react/src/graphql/fragment-spread-patterns.md
• Nested spreads: playgrounds/vite-react/src/graphql/nested-fragment-verification.ts

Code Examples

Simple fragment:

const userBasic = gql.default(({ fragment }) =>
  fragment("UserBasic", "User")`{
    id
    name
    email
  }`(),
);

Fragment with variables:

const userConditional = gql.default(({ fragment }) =>
  fragment("ConditionalUser", "User")`($includeEmail: Boolean!) {
    id
    name
    email @include(if: $includeEmail)
  }`(),
);

Fragment spreading (Fragment → Fragment):

const userExtended = gql.default(({ fragment }) =>
  fragment("ExtendedUser", "User")`{
    ...${userBasic}
    createdAt
    updatedAt
  }`(),
);

Operation spreading fragment (callback builder):

const getUserQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: {
      ...$var("id").ID("!"),
      ...$var("includeEmail").Boolean("!"),
    },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...userConditional.spread({ includeEmail: $.includeEmail }),
      })),
    }),
  }),
);

Common Patterns

✅ Fragment composition via tagged template:

const baseFields = gql.default(({ fragment }) =>
  fragment("UserBase", "User")`{ id name }`(),
);
const extendedFields = gql.default(({ fragment }) =>
  fragment("UserExtended", "User")`{
    ...${baseFields}
    email
  }`(),
);

✅ Operation declares all variables:

const getUserQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: {
      ...$var("id").ID("!"),
      ...$var("includeEmail").Boolean("!"), // ALL variables, including fragment requirements
    },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...userConditional.spread({ includeEmail: $.includeEmail }),
      })),
    }),
  }),
);

❌ Auto-merge expectation (WRONG):

// Fragment declares $includeEmail
const frag = gql.default(({ fragment }) =>
  fragment("F", "User")`($includeEmail: Boolean!) {
    id name email @include(if: $includeEmail)
  }`(),
);
// Operation does NOT auto-inherit variables — must declare includeEmail explicitly
const badQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: { ...$var("id").ID("!") }, // Missing includeEmail!
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...frag.spread(), // Will fail — $includeEmail not in scope
      })),
    }),
  }),
);

Topic 3: operation

Concept

Operations define the GraphQL query/mutation/subscription structure with variables, arguments, and field selections.

Operation Types

1. Tagged template operation — Simple operations without fragment spreads
2. Callback builder operation — Complex operations with spreads, aliases, $colocate

Variable Handling

Operations declare the contract:

• All variables must be declared at operation level
• Fragment variables are NOT auto-merged
• In callback builder, use $var("name").Type("!") to declare variables

Documentation References

• Examples: playgrounds/vite-react/src/graphql/operations.ts
• Callback-only features: playgrounds/vite-react/src/graphql/callback-builder-features.ts

Code Examples

Simple query (tagged template):

const getUsers = gql.default(({ query }) =>
  query("GetUsers")`{
    users {
      id
      name
    }
  }`(),
);

Query with variables (tagged template):

const getUser = gql.default(({ query }) =>
  query("GetUser")`($id: ID!) {
    user(id: $id) {
      id
      name
      email
    }
  }`(),
);

Query with fragment spread (callback builder):

const getUserWithFragment = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUserWithFragment",
    variables: {
      ...$var("id").ID("!"),
    },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...userFields.spread(),
      })),
    }),
  }),
);

Mutation (tagged template):

const createUser = gql.default(({ mutation }) =>
  mutation("CreateUser")`($input: CreateUserInput!) {
    createUser(input: $input) {
      id
      name
    }
  }`(),
);

Common Patterns

✅ Simple query (tagged template):

const getUserQuery = gql.default(({ query }) =>
  query("GetUser")`($id: ID!) {
    user(id: $id) {
      id
      name
      posts {
        id
        title
      }
    }
  }`(),
);

✅ Operation with multiple variables (callback builder):

const getUserPosts = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUserPosts",
    variables: {
      ...$var("id").ID("!"),
      ...$var("limit").Int(),
      ...$var("offset").Int(),
    },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...f.posts({ limit: $.limit, offset: $.offset })(({ f }) => ({
          id: f.id,
          title: f.title,
        })),
      })),
    }),
  }),
);

Topic 4: union

Concept

Union types in GraphQL represent a value that could be one of several types. soda-gql handles union types using standard GraphQL inline fragment syntax in tagged templates.

Union Member Selection

Union handling uses standard GraphQL inline fragment syntax (... on TypeName { fields }). Always include __typename for type discrimination:

const searchQuery = gql.default(({ query }) =>
  query("Search")`($term: String!) {
    search(term: $term) {
      __typename
      ... on User {
        id
        name
      }
      ... on Organization {
        id
        name
        members
      }
    }
  }`(),
);

Documentation References

• Union verification: playgrounds/vite-react/src/graphql/union-type-verification.ts
• Callback-only features: playgrounds/vite-react/src/graphql/callback-builder-features.ts

Code Examples

Union field selection (tagged template):

const searchQuery = gql.default(({ query }) =>
  query("Search")`($term: String!) {
    search(term: $term) {
      __typename
      ... on User {
        id
        name
        email
      }
      ... on Post {
        id
        title
        content
      }
    }
  }`(),
);

Union with fragment spread (callback builder):

const userFields = gql.default(({ fragment }) =>
  fragment("UserFields", "User")`{ id name email }`(),
);
const postFields = gql.default(({ fragment }) =>
  fragment("PostFields", "Post")`{ id title content }`(),
);
const searchQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "Search",
    variables: { ...$var("term").String("!") },
    fields: ({ f, $ }) => ({
      ...f.search({ term: $.term })(({ f }) => ({
        __typename: f.__typename,
        ...userFields.spread(),
        ...postFields.spread(),
      })),
    }),
  }),
);

Common Patterns

✅ Always include __typename:

const q = gql.default(({ query }) =>
  query("Search")`($term: String!) {
    search(term: $term) {
      __typename
      ... on TypeA { id fieldA }
      ... on TypeB { id fieldB }
    }
  }`(),
);

✅ Exhaustive member handling:

const q = gql.default(({ query }) =>
  query("SearchAll")`($term: String!) {
    search(term: $term) {
      __typename
      ... on User { id name }
      ... on Organization { id name }
      ... on Bot { id label }
    }
  }`(),
);

Topic 5: directive

Concept

GraphQL directives modify field behavior (@include, @skip) or provide metadata for tools. soda-gql supports standard and custom directives.

Directive Types

1. Standard directives: @include(if: Boolean), @skip(if: Boolean)
2. Custom directives: Defined in schema, used for metadata or tooling

Directive Syntax

Tagged template with static values:

gql.default(({ fragment }) =>
  fragment("UserFields", "User")`{
    id
    name
    email @include(if: true)
  }`(),
);

Tagged template with variables:

gql.default(({ fragment }) =>
  fragment("ConditionalUser", "User")`($includeEmail: Boolean!) {
    id
    name
    email @include(if: $includeEmail)
  }`(),
);

Documentation References

• Directive verification: playgrounds/vite-react/src/graphql/directive-verification.ts

Code Examples

@include directive:

const conditionalFields = gql.default(({ fragment }) =>
  fragment("ConditionalUser", "User")`($showEmail: Boolean!) {
    id
    name
    email @include(if: $showEmail)
  }`(),
);

@skip directive:

const fields = gql.default(({ fragment }) =>
  fragment("SkipEmail", "User")`($hideEmail: Boolean!) {
    id
    name
    email @skip(if: $hideEmail)
  }`(),
);

Custom directive:

// Assuming schema has: directive @sensitive on FIELD_DEFINITION
const userFields = gql.default(({ fragment }) =>
  fragment("SensitiveUser", "User")`{
    id
    name
    socialSecurityNumber @sensitive
  }`(),
);

Common Patterns

✅ Conditional field inclusion (callback builder with fragment spread):

const detailsFragment = gql.default(({ fragment }) =>
  fragment("UserDetails", "User")`($includeDetails: Boolean!) {
    bio @include(if: $includeDetails)
    website @include(if: $includeDetails)
  }`(),
);
const getUserQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: {
      ...$var("id").ID("!"),
      ...$var("includeDetails").Boolean("!"),
    },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        id: f.id,
        name: f.name,
        ...detailsFragment.spread({ includeDetails: $.includeDetails }),
      })),
    }),
  }),
);

• metadata — Directive metadata for tooling

Topic 6: metadata

Concept

soda-gql allows attaching metadata to fragments and operations for build-time processing (e.g., component mapping, documentation generation). Metadata is passed as an argument to the template call.

Metadata APIs

Static metadata — passed as argument to the template call:

const frag = gql.default(({ fragment }) =>
  fragment("UserFields", "User")`{
    id
    name
  }`({
    metadata: { component: "UserCard" },
  }),
);

Callback metadata — receives variables for dynamic values:

const frag = gql.default(({ fragment }) =>
  fragment("UserFields", "User")`($userId: ID!) {
    id
    name
  }`({
    metadata: ({ $ }: { $: { userId: string } }) => ({
      cacheKey: `user:${$.userId}`,
    }),
  }),
);

Documentation References

• Callback-only features: playgrounds/vite-react/src/graphql/callback-builder-features.ts
• Metadata verification: playgrounds/vite-react/src/graphql/metadata-verification.ts

Code Examples

Static fragment metadata:

const userFragment = gql.default(({ fragment }) =>
  fragment("UserCard", "User")`{
    id
    name
    email
  }`({
    metadata: { component: "UserCard", description: "User profile data" },
  }),
);

Callback metadata with variables:

const userFragment = gql.default(({ fragment }) =>
  fragment("CachedUser", "User")`($userId: ID!) {
    id
    name
    email
  }`({
    metadata: ({ $ }: { $: { userId: string } }) => ({
      cacheKey: `user:${$.userId}`,
    }),
  }),
);

Callback builder operation with metadata:

const q = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: { ...$var("id").ID("!") },
    metadata: ({ $, fragmentMetadata }) => ({
      entityId: $.id,
      fragmentCount: fragmentMetadata?.length ?? 0,
    }),
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...userFragment.spread(),
      })),
    }),
  }),
);

Common Patterns

✅ Component mapping:

gql.default(({ fragment }) =>
  fragment("UserProfile", "User")`{ id name }`({
    metadata: { component: "UserProfile" },
  }),
);

✅ Dynamic cache key:

gql.default(({ fragment }) =>
  fragment("CachedUser", "User")`($id: ID!) { id name }`({
    metadata: ({ $ }: { $: { id: string } }) => ({
      cacheKey: `user:${$.id}`,
    }),
  }),
);

Topic 7: setup

Concept

Setting up a new soda-gql project involves config file creation, schema setup, and initial codegen.

Setup Steps

1. Install dependencies:

``bash bun add @soda-gql/core @soda-gql/builder bun add -d @soda-gql/cli ``

1. Add framework plugin (optional but recommended):

``bash # For Vite bun add -d @soda-gql/vite-plugin # For Next.js bun add -d @soda-gql/next-plugin ``

1. Create config file (`soda-gql.config.ts`):

```typescript import { defineConfig } from '@soda-gql/config';

export default defineConfig({ outdir: './src/graphql/generated', schemas: { default: { schemaFiles: ['./schema.graphql'], }, }, }); ```

1. Run initial codegen:

``bash bun run soda-gql codegen schema ``

1. Configure build plugin (Vite example):

```typescript // vite.config.ts import { sodaGql } from '@soda-gql/vite-plugin';

export default { plugins: [sodaGql()], }; ```

Documentation References

• Main README: README.md — Installation and quick start
• Playground examples: playgrounds/vite-react/src/graphql/ — Working examples of all features

Common Issues

Issue: codegen fails with "config not found"

• Check config file is named correctly: soda-gql.config.{ts,js,mjs}
• Check config exports with export default

Issue: "Cannot find module '@soda-gql/core'"

• Run bun install to install dependencies
• Check package.json includes @soda-gql packages

Issue: Types not updating in editor

• Restart TypeScript server
• Check outdir matches tsconfig include paths

• lsp — Editor integration

Topic 8: lsp

Concept

soda-gql provides LSP (Language Server Protocol) integration for real-time diagnostics, autocomplete, and hover information in editors.

LSP Features

1. Real-time diagnostics: Type errors, invalid fields, syntax errors
2. Autocomplete: Field names, types, directives
3. Hover information: Type info, documentation
4. Go to definition: Jump to schema type definitions

Editor Setup

VS Code:

1. Install LSP extension (if available)
2. Configure workspace settings:

``json { "soda-gql.configPath": "./soda-gql.config.ts" } ``

Other editors:

• Use language server client compatible with your editor
• Point to soda-gql LSP server

LSP Diagnostics

The LSP validates:

• Field existence on types
• Argument types and required args
• Fragment type compatibility
• Variable types
• Directive usage

Common Issues

Issue: LSP not providing diagnostics

• Check config file is found (found: true in project detection)
• Restart editor/LSP server
• Check LSP logs for errors

Issue: False positive errors

• Run bun run soda-gql codegen schema to sync generated types
• Check schema files are up to date

Related Topics

• codegen — Keeping LSP in sync with schema

Topic 9: codegen

Concept

soda-gql codegen generates TypeScript types from GraphQL schemas (schema codegen) and validates/generates types from tagged templates (typegen).

Codegen Commands

1. Schema codegen:

``bash bun run soda-gql codegen schema ``

• Reads schema files from config
• Generates runtime type system in outdir
• Creates fragment and query builder types

1. Type generation (typegen):

``bash bun run soda-gql typegen ``

• Scans codebase for tagged templates
• Validates field selections against schema
• Generates TypeScript types for fragments/operations

Build Integration

Development workflow:

1. Edit schema files
2. Run bun run soda-gql codegen schema
3. Edit fragments/operations
4. Build plugin auto-runs typegen during build

Watch mode (if supported):

bun run soda-gql codegen schema --watch

Documentation References

• Monorepo infrastructure: docs/guides/monorepo-infrastructure.md — Build system

Common Issues

Issue: "Schema file not found"

• Check schemaFiles paths in config are relative to config file
• Use Read tool to verify file exists at expected path

Issue: Typegen shows "unknown field"

• Run schema codegen first: bun run soda-gql codegen schema
• Check field name spelling matches schema

Issue: Generated types not updating

• Delete generated directory and re-run codegen
• Check outdir in config matches import paths

• lsp — Real-time validation vs build-time codegen

Topic 10: colocation

Concept

Fragment colocation places fragment definitions near the components that use them, improving code organization and enabling build-time optimizations.

Colocation Patterns

$colocate in callback builder spread:

const userQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUser",
    variables: { ...$var("id").ID("!") },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        id: f.id,
        ...userFragment.spread({ $colocate: true }),
      })),
    }),
  }),
);

Component colocation:

// UserCard.tsx
export const userCardFragment = gql.default(({ fragment }) =>
  fragment("UserCardFields", "User")`{
    id
    name
    email
    avatarUrl
  }`(),
);
export function UserCard({ user }) {
  // Component uses fragment data
}

Build-Time Processing

Colocation enables:

• Dead code elimination (unused fragments removed)
• Component-fragment association tracking
• Automatic fragment composition

Documentation References

• Callback-only features: playgrounds/vite-react/src/graphql/callback-builder-features.ts — $colocate examples

Common Patterns

✅ Component-fragment pair:

// UserProfile.tsx
const userProfileFragment = gql.default(({ fragment }) =>
  fragment("UserProfile", "User")`{
    id
    name
    email
    bio
  }`(),
);
function UserProfile({ data }) {
  // Use fragment data
}

✅ Fragment composition with colocation:

const parentQuery = gql.default(({ query, $var }) =>
  query.operation({
    name: "GetUserPage",
    variables: { ...$var("id").ID("!") },
    fields: ({ f, $ }) => ({
      ...f.user({ id: $.id })(({ f }) => ({
        ...profileFragment.spread({ $colocate: true }),
        ...settingsFragment.spread({ $colocate: true }),
      })),
    }),
  }),
);

2. Use Grep to search docs/guides/ and playgrounds/
3. Read matching files and synthesize answer
4. Reference specific documentation sections

Example: User asks "How do I add pagination?"

1. Grep for "pagination" in docs and playground
2. If not found, explain general approach:

• Add limit/offset arguments to field
• Use variables in operation
• Show example with args

1. Suggest related topics: operation, fragment
