var ErrNoTests = errors.New("no tests found")

ErrNoTests is reported by TestSpec when there aren't any tests to run.

	"encore_local",

Types

type ArtifactString

type ArtifactString string

func (ArtifactString) Expand

func (a ArtifactString) Expand(artifactDir paths.FS) string

func (ArtifactString) Join

func (a ArtifactString) Join(strs ...string) ArtifactString

type ArtifactStrings

type ArtifactStrings []ArtifactString

func (ArtifactStrings) Expand

func (a ArtifactStrings) Expand(artifactDir paths.FS) []string

type BuildInfo

type BuildInfo struct {
	BuildTags          []string
	CgoEnabled         bool
	StaticLink         bool
	Debug              bool
	GOOS, GOARCH       string
	KeepOutput         bool
	Revision           string
	UncommittedChanges bool

	// MainPkg is the path to the existing main package to use, if any.
	MainPkg option.Option[paths.Pkg]

	// Overrides to explicitly set the GoRoot and EncoreRuntime paths.
	// if not set, they will be inferred from the current executable.
	GoRoot         option.Option[paths.FS]
	EncoreRuntimes option.Option[paths.FS]

	// UseLocalJSRuntime specifies whether to override the installed Encore version
	// with the local JS runtime.
	UseLocalJSRuntime bool

	// Logger allows a custom logger to be used by the various phases of the builder.
	Logger option.Option[zerolog.Logger]
}

func DefaultBuildInfo

func DefaultBuildInfo() BuildInfo

DefaultBuildInfo returns a BuildInfo with default values. It can be modified afterwards.

type BuildOutput

type BuildOutput interface {
	GetArtifactDir() paths.FS
	GetEntrypoints() []Entrypoint
}

type Cmd

type Cmd struct {
	// The command to execute, with arguments.
	Command []string

	// Additional env variables to pass in.
	Env []string
}

Cmd defines a command to run. It's like CmdSpec, but uses expanded paths instead of ArtifactStrings. A CmdSpec can be turned into a Cmd using Expand.

type CmdSpec

type CmdSpec struct {
	// The command to execute. Can either be a filesystem path
	// or a path to a binary (using "${ARTIFACT_DIR}" as a placeholder).
	Command ArtifactStrings `json:"command"`

	// Additional env variables to pass in.
	Env ArtifactStrings `json:"env"`

	// PrioritizedFiles are file paths that should be prioritized when
	// building a streamable docker image.
	PrioritizedFiles ArtifactStrings `json:"prioritized_files"`
}

CmdSpec is a specification for a command to run.

The fields can refer to file paths within the artifact directory using the "${ARTIFACT_DIR}" placeholder (substituted with os.ExpandEnv). This is necessary when building docker images, as otherwise the file paths will refer to the wrong filesystem location in the built docker image.

func (*CmdSpec) Expand

func (s *CmdSpec) Expand(artifactDir paths.FS) Cmd

type CompileParams

type CompileParams struct {
	Build       BuildInfo

	WorkingDir  string

	// Override to explicitly allow the Encore version to be set.
	EncoreVersion option.Option[string]
}

type CompileResult

type CompileResult struct {
	Outputs []BuildOutput
}

type Entrypoint

type Entrypoint struct {
	// How to run this entrypoint.
	Cmd CmdSpec `json:"cmd"`
	// Services hosted by this entrypoint.
	Services []string `json:"services"`
	// Gateways hosted by this entrypoint.

	// These artifacts are assumed to be relocatable.
	ArtifactDir paths.FS `json:"artifact_dir"`

	// The entrypoints that are part of this build output.
	Entrypoints []Entrypoint `json:"entrypoints"`
}

	GenUserFacing(context.Context, GenUserFacingParams) error
	UseNewRuntimeConfig() bool
	NeedsMeta() bool
	Close() error
}

type JSBuildOutput

type JSBuildOutput struct {
	// NodeModules are the node modules that the build artifacts rely on.
	// It's None if the artifacts don't rely on any node modules.
	NodeModules option.Option[paths.FS] `json:"node_modules"`

	// The folder containing the build artifacts.
	// These artifacts are assumed to be relocatable.
	ArtifactDir paths.FS `json:"artifact_dir"`

	// PackageJson is the path to the package.json file to use.
	PackageJson paths.FS `json:"package_json"`

	// The entrypoints that are part of this build output.
	Entrypoints []Entrypoint `json:"entrypoints"`

	// Whether the build output uses the local runtime on the builder,
	// as opposed to installing a published release via e.g. 'npm install'.
	UsesLocalRuntime bool `json:"uses_local_runtime"`
